Description

Technical Field

[0001] This utility model belongs to the field of motor, generator, electric vehicle and mechanical technology, and in particular relates to a stator, rotor, motor, generator and electric vehicle. Background Technology

[0002] Electric vehicles are vehicles that use onboard power sources to drive their wheels with electric motors and meet all road traffic and safety regulations. Generators are devices that convert mechanical energy into electrical energy; electric motors are devices that convert electrical energy into mechanical energy.

[0003] In the existing technology, an insulating layer is set in the groove of the stator or rotor. The insulating layer is mostly made of insulating paper or insulating glue. That is, the insulating paper or insulating glue is used separately. After the insulating glue is filled into the groove and solidifies, it is inconvenient for later maintenance, that is, it is inconvenient to remove the coil or flat wire in the groove. The insulating paper is set in the groove, which is not conducive to long-term use, that is, the insulation effect is poor after long-term use.

[0004] Therefore, it is necessary to make changes. Summary of the Invention

[0005] The purpose of this invention is to provide a stator, rotor, motor, generator, or electric vehicle to solve the problems of poor insulation and inconvenient maintenance in the existing technology.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a stator, comprising: mounting through holes evenly distributed around the axis of the stator; an insulating layer disposed within the mounting through holes, the insulating layer comprising a first insulating layer and a second insulating layer, the first insulating layer and the second insulating layer being disposed adjacent to each other, wherein the second insulating layer is in contact with the inner wall of the mounting through holes; the first insulating layer is insulating paper, and the second insulating layer is insulating adhesive. The first insulating layer, i.e., the insulating paper, is installed on the coil or flat wire, and the flat wire or coil and the first insulating layer, i.e., the insulating paper, are installed within the mounting through holes, leaving a gap between the insulating paper and the interior of the mounting through holes. The second insulating layer, i.e., the insulating adhesive, is then filled into the gap between the insulating paper and the mounting through holes. The insulating paper and the insulating adhesive provide double-layer protection for the coil or flat wire, improving the insulation isolation effect between the coil or flat wire and the stator. After the insulating adhesive, insulating paper, and stator solidify, it does not affect the subsequent removal of the coil or flat wire; that is, the coil or flat wire is in contact with the insulating paper, facilitating removal.

[0007] Preferably, the insulating layer further includes a third insulating layer, with the second insulating layer disposed between the first and third insulating layers. The third insulating layer contacts the inner wall of the mounting through hole, and the third insulating layer is insulating paper. A second insulating layer, i.e., insulating adhesive, is disposed between the first insulating layer (i.e., insulating paper) and the third insulating layer (i.e., insulating paper). The coil or flat wire contacts the first insulating layer (i.e., insulating paper), facilitating later removal of the flat wire or coil. Since the insulating paper does not contact the coil or flat wire or the stator, it facilitates later removal of the coil or flat wire.

[0008] Preferably, the stator further includes a conductive block disposed within the mounting through hole. The outer contour of the conductive block matches the mounting through hole and is detachably disposed within the mounting through hole. The insulating layer is located in the gap between the conductive block and the mounting through hole. The conductive block is a material that generates a magnetic field when the input current is applied. This arrangement allows for motor configuration according to customer needs, such as using aluminum or copper materials to manufacture the stator. The conductive block replaces multiple windings or multiple flat wires in the prior art, facilitating installation and subsequent maintenance, and preventing damage to the insulation layer during installation.

[0009] Preferably, the conductive block is a copper block. Using pure copper material to manufacture the stator and install it on the motor makes the motor more durable, the pure copper core motor is quieter, and the pure copper motor is more energy-efficient, i.e., it generates less heat, allows for smooth current flow, does not waste heat, and saves more electricity.

[0010] Another objective of this invention is to provide a rotor comprising: mounting through holes evenly distributed around the rotor's axis; and an insulating layer disposed within the mounting through holes. The insulating layer includes a first insulating layer and a second insulating layer, arranged adjacent to each other. The second insulating layer contacts the inner wall of the mounting through holes. The first insulating layer is insulating paper, and the second insulating layer is insulating adhesive. A coil or flat wire is mounted on the first insulating layer (insulating paper). The flat wire or coil and the first insulating layer (insulating paper) are installed within the mounting through holes, leaving a gap between the insulating paper and the inside of the mounting through holes. The second insulating layer (insulating adhesive) is then filled into the gap between the insulating paper and the mounting through holes. The insulating paper and insulating adhesive provide double-layer protection for the coil or flat wire, improving the insulation isolation effect between the coil or flat wire and the rotor. After the insulating adhesive, insulating paper, and rotor solidify, it does not affect the subsequent removal of the coil or flat wire; that is, the coil or flat wire is in contact with the insulating paper, facilitating removal.

[0011] Preferably, the insulating layer further includes a third insulating layer, with the second insulating layer disposed between the first and third insulating layers. The third insulating layer contacts the inner wall of the mounting through hole, and the third insulating layer is insulating paper. A second insulating layer, i.e., insulating adhesive, is disposed between the first insulating layer (i.e., insulating paper) and the third insulating layer (i.e., insulating paper). The coil or flat wire contacts the first insulating layer (i.e., insulating paper), facilitating later removal of the flat wire or coil. Since the insulating paper does not contact the coil or flat wire or the rotor, it facilitates later removal of the coil or flat wire.

[0012] Preferably, the rotor further includes a conductive block disposed within the mounting through hole. The outer contour of the conductive block matches the mounting through hole and is detachably disposed within it. The insulating layer is located in the gap between the conductive block and the mounting through hole. The conductive block is a material that generates a magnetic field when the input current is applied. This arrangement allows for motor configuration according to customer needs, such as using aluminum or copper to manufacture the rotor. The conductive block replaces multiple windings or flat wires in existing technologies, facilitating installation and subsequent maintenance, and preventing damage to the insulating layer during installation.

[0013] Preferably, the conductive block is a copper block. Using pure copper material to manufacture the rotor and installing it on the motor makes the motor more durable, the pure copper core motor is quieter, and the pure copper motor is more energy-efficient, i.e., it generates less heat, allows for smooth current flow, does not waste heat, and saves more electricity.

[0014] Another objective of this invention is to provide an electric motor equipped with the stator and / or rotor described in this invention. The stator or rotor provided by this invention is used on the motor, and the coil or flat wire is double-protected by insulating paper and insulating adhesive on the stator or rotor, improving the insulation isolation effect between the coil or flat wire and the stator. After the insulating adhesive, insulating paper, and stator and / or rotor solidify, it does not affect the subsequent removal of the coil or flat wire; that is, the coil or flat wire is in contact with the insulating paper, facilitating removal.

[0015] Another objective of this invention is to provide a generator equipped with the stator and / or rotor described herein. The generator motor uses the stator or rotor provided by this invention, with insulating paper and insulating adhesive providing double-layer protection for the coils or flat wires, improving the insulation isolation between the coils or flat wires and the stator. After the insulating adhesive, insulating paper, and stator and / or rotor solidify, it does not affect the subsequent removal of the coils or flat wires; that is, the coils or flat wires are in contact with the insulating paper, facilitating removal.

[0016] Another objective of this invention is to provide an electric vehicle equipped with the motor and / or generator described in this invention.

[0017] This utility model has the following advantages compared with the prior art:

[0018] This invention replaces the grooves on the stator and / or rotor with through holes for installation. The conductive block can be inserted into the through hole to complete the installation. This design avoids damage to the coil or flat wire and the insulation layer of the conductive block, while also facilitating installation and subsequent maintenance.

[0019] This invention provides a first insulating layer, i.e., insulating paper, which is installed on the coil or flat wire conductive block. The coil or flat wire, the conductive block, and the first insulating layer (i.e., insulating paper) are installed inside a mounting through hole, leaving a gap between the insulating paper and the inside of the mounting through hole. A second insulating layer, i.e., insulating adhesive, is then filled into the gap between the insulating paper and the mounting through hole. The insulating paper and insulating adhesive provide double-layer protection for the coil or flat wire and the conductive block, improving the insulation isolation effect between the coil or flat wire and the conductive block and the stator or rotor. After the insulating adhesive, insulating paper, and stator or rotor solidify, it does not affect the subsequent removal of the coil or flat wire and the conductive block; that is, the coil or flat wire and the conductive block are in contact with the insulating paper, facilitating removal.

[0020] This invention provides a first insulating layer, i.e., insulating paper, that is, mounted on a coil or flat wire conductive block.

A third insulating layer is installed inside the mounting through hole and contacts the inner wall of the mounting through hole. A gap is left between the first and third insulating layers. A second insulating layer, i.e., insulating adhesive, is filled into the gap between the first and second insulating layers. The insulating paper and insulating adhesive provide double protection for the coil or flat wire conductive block, improving the insulation isolation effect between the coil or flat wire conductive block and the stator or rotor.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0041] like Figure 1 , Figure 4 , Figure 16 As shown, a stator 1 includes mounting through holes and an insulating layer 2. The mounting through holes are evenly distributed around the axis of the stator 1. The insulating layer 2 is disposed within the mounting through holes. The insulating layer 2 includes a first insulating layer 2-1 and a second insulating layer 2-2, which are disposed adjacent to each other. The second insulating layer 2-2 is in contact with the inner wall of the mounting through hole. The first insulating layer 2-1 is insulating paper, and the second insulating layer 2-2 is insulating adhesive. The first insulating layer 2-1, i.e., insulating paper, is installed on the flat wire and / or conductive block 3, or the flat wire and / or conductive block 3 and the first insulating layer 2-1, i.e., insulating paper, are installed inside the mounting through hole of the stator 1. A gap is left between the insulating paper and the inner wall of the mounting through hole on the stator 1. The second insulating layer 2-2, i.e., insulating adhesive, is filled into the gap between the insulating paper and the inner wall of the mounting through hole. The insulating paper and insulating adhesive provide double-layer insulation protection for the flat wire and / or conductive block 3, improving the insulation effect between the flat wire and / or conductive block 3 and the stator 1. Since the flat wire and / or conductive block 3 does not come into contact with the insulating adhesive, it is convenient to remove the coil, flat wire, and conductive block 3 from the stator 1.

[0042] Existing technology uses grooves on the stator, which can easily damage the insulation layer during the installation of coil windings or flat wires. This is because if the slot opening in stator 1 is too small, it makes wire unloading difficult; if the slot opening is too large, it leads to uneven air gap magnetic flux distribution and increased tooth harmonics. This product improves upon the grooves on stator 1 by replacing them with through holes. The conductive block 3 can be directly inserted into the through hole for installation, thus avoiding damage to the surface insulation layer of the conductive block 3. The through hole itself does not have a slot design, preventing uneven air gap magnetic flux distribution and increased tooth harmonics.

[0043] Continue as Figure 1 , Figure 4 , Figure 16As shown, the first insulating layer 2-1 is RMR motor insulating paper, which is a general term for electrical insulating paper. It is used as an insulating material for cables, coils, and other electrical equipment. The second insulating layer 2-2 is inorganic adhesive 5032, which is a composite adhesive with good electrical insulation properties. It can be used for casting cable joints, impregnating motor, electrical appliance, and generator windings, as well as for sealing insulation of transformers, capacitors, or radio devices, and as a surface protective layer for electrical and electronic components. The insulating paper isolates the coil or flat wire from direct contact with the insulating adhesive. This way, after the insulating adhesive, insulating paper, and stator solidify, it does not affect the subsequent removal of the coil or flat wire. That is, the coil or flat wire is in contact with the insulating paper, and the insulating paper is in contact with the coil or flat wire, making it easy to remove.

[0044] Continue as Figure 1 , Figure 4 , Figure 16 As shown, in specific use: the first insulating layer 2-1 is folded into a ring shape, and the ring-shaped insulating paper is installed in the groove of the stator 1. A gap is left between the outer surface of the ring-shaped insulating paper and the inner wall of the groove. Flat wires and / or conductive blocks 3 are installed in the internal space of the first insulating layer 2-1, i.e., the ring-shaped insulating paper. After the flat wires and / or conductive blocks 3 are installed, the second insulating layer 2-2, i.e., insulating adhesive, is filled into the gap between the outer surface of the ring-shaped insulating paper and the groove.

[0045] like Figure 1 , Figure 3 , Figure 13 As shown, the insulation layer also includes a third insulation layer 2-3. A second insulation layer 2-2 is positioned between the first insulation layer 2-1 and the third insulation layer 2-3. The third insulation layer 2-3 contacts the inner wall of the mounting through-hole and is insulating paper. The second insulation layer 2-2 (insulating adhesive) is positioned between the first insulation layer 2-1 (insulating paper) and the third insulation layer 2-3 (insulating paper). The flat wire contacts the first insulation layer 2-1 (insulating paper), facilitating its later removal. Since the insulating paper does not contact the flat wire or the stator 1, it is easy to remove the flat wire later. This design, with the insulating adhesive positioned between the two insulating papers, prevents the insulation layer from directly contacting the flat wire in the stator 1 groove, making it convenient to remove the flat wire from the groove.

[0046] like Figure 1 , Figure 3As shown, in specific use: The first insulating layer 2-1 is folded into a ring shape, and the ring-shaped insulating paper is installed in the groove of the stator 1, with the outer surface of the ring-shaped insulating paper in contact with the inside of the groove. The third insulating layer 2-3 is folded into a ring shape, and the ring-shaped insulating paper is installed inside the folded ring shape of the first insulating layer 2-1. A space is left inside the third insulating paper 2-3, and a flat wire is installed in the space inside the ring-shaped insulating paper of the first insulating layer 2-1. A gap is left between the first insulating paper 2-1 and the third insulating paper 2-3; this gap is used to fill the second insulating paper 2-2, i.e., insulating adhesive. After the coil is installed, the second insulating layer 2-2, i.e., the insulating adhesive, is installed in the gap between the first insulating paper 2-1 and the third insulating paper 2-3, that is, the insulating adhesive is filled into the gap between the first insulating paper 2-1 and the third insulating paper 2-3.

[0047] like Figure 2 and Figure 5 As shown, a conductive block 3 is installed within a mounting through hole on the stator 1. The outer contour of the conductive block 3 matches the mounting through hole and is detachably installed within it. The insulating layer 2 is located in the gap between the conductive block 3 and the mounting through hole. The conductive block 3 is made of a material that generates a magnetic field for the input current. This allows the stator 1 to be matched according to customer requirements, and the stator can be made of aluminum or copper. The conductive block 3 replaces the multiple windings or multiple flat wires in the prior art, facilitating installation and subsequent maintenance, and preventing damage to the insulation layer during installation.

[0048] In practical application, the first insulating layer 2-1 is folded into a ring shape, and the ring-shaped insulating paper is installed inside the mounting through hole of the stator 1. A gap is left between the outer surface of the ring-shaped insulating paper and the mounting through hole. A conductive block 3 is installed inside the space of the ring-shaped insulating paper of the first insulating layer 2-1. After the conductive block 3 is installed, the second insulating layer 2-2 is installed in the gap between the ring-shaped insulating paper and the inner wall of the mounting through hole, that is, insulating glue is filled into the gap between the outer surface of the ring-shaped insulating paper and the mounting through hole.

[0049] like Figure 3 , Figure 13 As shown, the insulating layer 2 further includes a third insulating layer 203. The second insulating layer 203 is disposed between the first insulating layer 201 and the third insulating layer 203. The third insulating layer 203 is in contact with the inner wall of the mounting through hole and is made of insulating paper. The purpose of designing the third insulating layer 203 is to further improve the insulation effect between the conductive block 3 and the stator 1.

[0050] like Figure 2 , Figure 3 , Figure 5 , Figure 13As shown, the first insulating layer 2-1 is folded into a ring shape, and the ring-shaped insulating paper is installed in the mounting through hole of the stator 1. A gap is left between the outer surface of the ring-shaped insulating paper and the inner wall of the mounting through hole. The third insulating layer 2-3 is folded into a ring shape, and the ring-shaped insulating paper is also installed in the mounting through hole of the stator 1 and sleeved on the first insulating layer 2-1. The outer wall of the third insulating layer 2-3 contacts the inner wall of the mounting through hole of the stator 1. A gap is left between the inner wall of the third insulating layer 2-3 and the outer wall of the first insulating layer 201. A conductive block 3 is installed in the internal space of the ring-shaped insulating paper of the first insulating layer 2-1. In this way, the gap between the first insulating paper 2-1 and the third insulating paper 2-3 is filled with the second insulating layer 202, that is, the gap between the first insulating paper 2-1 and the third insulating paper 2-3 is used to fill the second insulating paper 2-2.

[0051] like Figure 2 , Figure 5 , Figure 12 As shown, the conductive block 3 on the stator 1 is a copper block or a hollow copper block. The conductive block 3 is made of pure copper material to manufacture the stator 1 and is installed on the motor to make the motor more durable. The pure copper core motor is quieter and more energy-efficient, with lower heat generation, smooth current flow, no heat waste, and greater energy saving.

[0052] like Figures 1-5 , Figure 11 , Figure 12 , Figure 13 , Figure 16 As stated, the working principle is as follows: When the motor is working, the windings undergo electromagnetic conversion through a certain voltage and current. The windings and the ground must be isolated by insulation. If the insulation is poor, it will cause winding grounding and inter-phase turn short circuits, which will prevent the motor from working properly and burn out or cause personal injury. Therefore, the motor must be insulated. The first insulating layer 2-1, i.e., insulating paper, is installed on the conductive block 3. The conductive block 3 and the first insulating layer 2-1, i.e., the insulating paper, are installed inside the mounting through hole, with a gap between the insulating paper and the inner wall of the mounting through hole. Then, the third insulating layer 203 is fitted onto the first insulating layer 2-1, with a gap between the third insulating layer 203 and the first insulating layer 2-1. This gap is used to fill the second insulating layer 202. The third insulating layer 203 is in contact with the inner wall of the mounting through hole on the stator 1. Finally, the second insulating layer 2-2, i.e., insulating adhesive, is filled into the gap between the third insulating layer 203 and the first insulating layer 2-1. In this way, the insulating paper, insulating adhesive, and insulating paper provide double-layer insulation protection for the conductive block 3, improving the insulation effect between the conductive block 3 and the stator 1. After the insulating adhesive and insulating paper solidify, it does not affect the subsequent removal of the conductive block 3. That is, the conductive block 3 is connected to the stator 1 through the insulating paper and does not directly contact the insulating adhesive, which facilitates subsequent removal and maintenance.

[0053] like Figures 1-5 , Figure 11 , Figure 12 , Figure 13 , Figure 16 The working principle is as follows: When the motor is working, the windings undergo electromagnetic conversion through a certain voltage and current. The windings and the ground must be insulated. Poor insulation will cause winding grounding and inter-phase / inter-turn short circuits, preventing the motor from working properly and potentially causing burnout or personal injury. Therefore, the motor must be insulated. The first insulating layer 2-1, i.e., insulating paper, is installed on the conductive block 3. The conductive block 3 and the first insulating layer 2-1 (insulating paper) are installed inside the mounting through hole, leaving a gap between the insulating paper and the inner wall of the mounting through hole. This gap is used to fill the second insulating layer 202. The second insulating layer 2-2 (insulating adhesive) is then filled into the gap between the first insulating layer 2-1 and the inner wall of the mounting through hole. This provides double-layer insulation protection for the conductive block 3, improving the insulation isolation between the conductive block 3 and the stator 1. After the insulating adhesive and insulating paper solidify, it does not affect the subsequent removal of the conductive block 3. The conductive block 3 is connected to the stator 1 through the insulating paper, without direct contact with the insulating adhesive, facilitating subsequent removal and maintenance.

[0054] like Figure 6 , Figure 9 , Figure 15 As shown, a rotor 4 includes mounting through holes and an insulating layer 2. The mounting through holes are evenly distributed around the axis of the rotor 4; the insulating layer 2 is disposed within the mounting through holes. The insulating layer 2 includes a first insulating layer 2-1 and a second insulating layer 2-2, which are disposed adjacent to each other. The second insulating layer 2-2 is in contact with the inner wall of the mounting through hole of the rotor 4. The first insulating layer 2-1 is insulating paper, and the second insulating layer 2-2 is insulating adhesive. The first insulating layer 2-1, i.e., insulating paper, is installed on the flat wire and / or conductive block 3. The flat wire and / or conductive block 3 and the first insulating layer 2-1, i.e., insulating paper, are installed in the mounting through hole of the rotor 4. A gap is left between the insulating paper and the inner wall of the mounting through hole. The second insulating layer 2-2, i.e., insulating adhesive, is filled into the gap between the insulating paper and the inner wall of the mounting through hole. The insulating paper and insulating adhesive provide double-layer insulation protection for the flat wire and / or conductive block 3, improving the insulation effect of the flat wire and / or conductive block 3. Since the flat wire and / or conductive block 3 do not come into contact with the insulating adhesive, it is easy to remove the flat wire and conductive block 3 from the stator 1.

[0055] Existing technology uses grooves on the rotor. These grooves can easily damage the insulation layer during the installation of coil windings or flat wires. If the rotor slot opening is too small, it's difficult to unload the wire; if the slot opening is too large, it leads to uneven air gap magnetic flux distribution and increased tooth harmonics. This product improves upon the grooves by replacing them with through holes. The conductive block 3 can be directly inserted into the through hole for installation, thus avoiding damage to the surface insulation layer of the conductive block 3. The through hole itself has no slot design, preventing uneven air gap magnetic flux distribution and increased tooth harmonics.

[0056] Continue as Figure 6 , Figure 9 , Figure 15 As shown, the first insulating layer 2-1 is RMR motor insulating paper, which is a general term for electrical insulating paper. It is used as an insulating material for cables, coils, and other electrical equipment. The second insulating layer 2-2 is inorganic adhesive 5032, which is a composite adhesive with good electrical insulation properties. It can be used for casting cable joints, impregnating motor, electrical appliance, and generator windings, as well as for sealing insulation of transformers, capacitors, or radio devices, and as a surface protective layer for electrical and electronic components. The insulating paper isolates the flat wire from direct contact with the insulating adhesive. This way, after the insulating adhesive, insulating paper, and stator solidify, it does not affect the subsequent removal of the flat wire. That is, the flat wire is in contact with the insulating paper, and the insulating paper is in contact with the flat wire, making it easy to remove.

[0057] Continue as Figure 6 , Figure 9 , Figure 15 As shown, in specific use: the first insulating layer 2-1 is folded into a ring shape, and the ring-shaped insulating paper is installed in the groove of the rotor 4. A gap is left between the outer surface of the ring-shaped insulating paper and the inner wall of the groove. Flat wires and / or conductive blocks 3 are installed in the internal space of the first insulating layer 2-1, i.e., the ring-shaped insulating paper. After the flat wires and / or conductive blocks 3 are installed, the second insulating layer 2-2, i.e., insulating adhesive, is filled into the gap between the outer surface of the ring-shaped insulating paper and the groove.

[0058] like Figure 6 , Figure 8 , Figure 14 As shown, the insulation layer also includes a third insulation layer 2-3. A second insulation layer 2-2 is positioned between the first insulation layer 2-1 and the third insulation layer 2-3. The third insulation layer 2-3 contacts the inner wall of the mounting through-hole and is insulating paper. The second insulation layer 2-2 (insulating adhesive) is positioned between the first insulation layer 2-1 (insulating paper) and the third insulation layer 2-3 (insulating paper). The flat wire contacts the first insulation layer 2-1 (insulating paper), facilitating its later removal. Since the insulating paper does not contact the flat wire or the rotor, it is easy to remove the flat wire later. This design, with the insulating adhesive positioned between the two insulating papers, prevents the insulation layer from directly contacting the rotor groove and the flat wire, making it convenient to remove the flat wire from the groove.

[0059] like Figure 8 , Figure 14As shown, in specific use: The first insulating layer 2-1 is folded into a ring shape, and the ring-shaped insulating paper is installed in the groove of the rotor 1, with the outer surface of the ring-shaped insulating paper in contact with the inner wall of the groove. The third insulating layer 2-3 is folded into a ring shape, and the ring-shaped insulating paper of the third insulating layer 2-3 is placed over the folded ring shape of the first insulating layer 2-1. A space is left inside the third insulating paper 2-3, and a coil or flat wire is installed in the space inside the ring-shaped insulating paper of the first insulating layer 2-1. A gap is left between the first insulating paper 2-1 and the third insulating paper 2-3, and this gap is used to fill the second insulating paper 2-2, i.e., insulating adhesive. After the flat wire or coil is installed, the second insulating layer 2-2, i.e., the insulating adhesive, is installed in the gap between the first insulating paper 2-1 and the third insulating paper 2-3, that is, the insulating adhesive is filled into the gap between the first insulating paper 2-1 and the third insulating paper 2-3.

[0060] like Figure 7 and Figure 10 As shown, a conductive block 3 is installed within a mounting through hole on the rotor 4. The outer contour of the conductive block 3 matches the mounting through hole and is detachably installed within it. The insulating layer 2 is located in the gap between the conductive block 3 and the mounting through hole. The conductive block 3 is made of a material that generates a magnetic field for the input current, allowing the rotor 4 to be customized according to customer needs, using either aluminum or copper materials. The conductive block 3 replaces the multiple windings or flat wires found in existing technologies, facilitating installation and subsequent maintenance, and preventing damage to the insulation layer during installation.

[0061] In practical application, the first insulating layer 2-1 is folded into a ring shape, and the ring-shaped insulating paper is installed inside the mounting through hole of the rotor 4. A gap is left between the outer surface of the ring-shaped insulating paper and the mounting through hole. A conductive block 3 is installed inside the space of the ring-shaped insulating paper of the first insulating layer 2-1. After the conductive block 3 is installed, the second insulating layer 2-2 is installed in the gap between the ring-shaped insulating paper and the inner wall of the mounting through hole, that is, insulating glue is filled into the gap between the outer surface of the ring-shaped insulating paper and the mounting through hole.

[0062] like Figure 8 , Figure 14 As shown, the insulating layer 2 further includes a third insulating layer 203. The second insulating layer 203 is disposed between the first insulating layer 201 and the third insulating layer 203. The third insulating layer 203 is in contact with the inner wall of the mounting through hole and is made of insulating paper. The purpose of designing the third insulating layer 203 is to further improve the insulation effect between the conductive block 3 and the rotor 4.

[0063] like Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 14As shown, the first insulating layer 2-1 is folded into a ring shape, and the ring-shaped insulating paper is installed in the mounting through hole of the rotor 4. A gap is left between the outer surface of the ring-shaped insulating paper and the inner wall of the mounting through hole. The third insulating layer 2-3 is folded into a ring shape, and the ring-shaped insulating paper is also installed in the mounting through hole of the stator 1 and sleeved on the first insulating layer 2-1. The outer wall of the third insulating layer 2-3 contacts the inner wall of the mounting through hole of the stator 1. A gap is left between the inner wall of the third insulating layer 2-3 and the outer wall of the first insulating layer 201. The conductive block 3 is installed in the internal space of the ring-shaped insulating paper of the first insulating layer 2-1. In this way, the gap between the first insulating paper 2-1 and the third insulating paper 2-3 is filled with the second insulating layer 202, that is, the gap between the first insulating paper 2-1 and the third insulating paper 2-3 is used to fill the second insulating paper 2-2 (insulating glue), which further improves the insulation effect between the conductive block 3 and the rotor 4.

[0064] Continue as Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 14 As shown, the conductive block 3 on the rotor 4 is a copper block, a hollow copper block. The conductive block 3 is made of pure copper material. The rotor 4 is made of pure copper material and installed on the motor, making the motor more durable. The pure copper core motor is quieter and more energy-efficient, with lower heat generation, smooth current flow, no heat waste, and greater energy saving.

[0065] like Figures 6-10 , Figure 11 , Figure 12 , Figure 14 , Figure 15 As stated, the working principle is as follows: When the motor is working, the windings undergo electromagnetic conversion through a certain voltage and current. The windings and the ground must be isolated by insulation. If the insulation is poor, it will cause winding grounding and inter-phase turn short circuits, which will prevent the motor from working properly and burn out or cause personal injury. Therefore, the motor must be insulated. The first insulating layer 2-1, i.e., insulating paper, is installed on the flat wire and conductive block 3. The flat wire, conductive block 3, and the first insulating layer 2-1 (i.e., insulating paper) are installed inside the mounting through hole, with a gap between the insulating paper and the inner wall of the mounting through hole. Then, the third insulating layer 203 is fitted onto the first insulating layer 2-1, with a gap between the third insulating layer 203 and the first insulating layer 2-1. This gap is used to fill the second insulating layer 202. The third insulating layer 203 is in contact with the inner wall of the mounting through hole on the rotor 4. Finally, the second insulating layer 2-2 (i.e., insulating adhesive) is filled into the gap between the third insulating layer 203 and the first insulating layer 2-1. In this way, the insulating paper, insulating adhesive, and insulating paper provide double-layer protection for the flat wire and conductive block 3, improving the insulation isolation effect between the flat wire and conductive block 3 and the rotor 4. After the insulating adhesive and insulating paper solidify, it does not affect the subsequent removal of the flat wire and conductive block 3. That is, the flat wire and conductive block 3 are connected to the rotor 4 through the insulating paper, without direct contact with the insulating adhesive, facilitating subsequent removal and maintenance.

[0066] like Figures 6-10 , Figure 11 , Figure 12 , Figure 14 , Figure 15 The working principle is as follows: When the motor is working, the windings undergo electromagnetic conversion through a certain voltage and current. The windings and the ground must be insulated. Poor insulation will cause winding grounding and inter-phase / inter-turn short circuits, preventing the motor from working properly and potentially causing burnout or personal injury. Therefore, the motor must be insulated. The first insulation layer 2-1, i.e., insulating paper, is installed on the flat wire and conductive block 3. The flat wire, conductive block 3, and the first insulation layer 2-1 (insulating paper) are installed inside the mounting through hole, leaving a gap between the insulating paper and the inner wall of the mounting through hole. This gap is used to fill the second insulation layer 202. The second insulation layer 2-2 (insulating adhesive) is filled into the gap between the first insulation layer 2-1 and the inner wall of the mounting through hole. In this way, the insulating paper and insulating adhesive provide double-layer insulation protection for the flat wire and conductive block 3, improving the insulation effect between the flat wire and conductive block 3 and the rotor 4. After the insulating adhesive and insulating paper solidify, it does not affect the subsequent removal of the flat wire and conductive block 3. That is, the flat wire and conductive block 3 are connected to the rotor 4 through the insulating paper, without direct contact with the insulating adhesive, facilitating subsequent removal and maintenance.

[0067] like Figure 5 and Figure 10 As shown, an electric motor is provided with the stator and / or rotor of this invention. The stator or rotor of this invention is used on the motor, and the stator or rotor provides double-layer insulation protection for the coils or flat wires and conductive blocks 3 with insulating paper and insulating adhesive, improving the insulation isolation effect between the flat wires and conductive blocks 3 and the stator and / or rotor. After the insulating adhesive, insulating paper, and stator and / or rotor solidify, it does not affect the subsequent removal of the flat wires and conductive blocks 3; that is, the flat wires and conductive blocks 3 are in contact with the insulating paper, and the insulating paper is in contact with the stator 1 and / or rotor 4 through the insulating adhesive, facilitating removal.

[0068] (Not shown in the diagram) End caps are installed at both ends of the stator or rotor. Multiple connecting wires are arranged in series within the end caps according to the motor wiring method. One end of each of the remaining wire ends is electrically connected to a conductive block 3 on the stator or rotor, and the other end is electrically connected to an external power supply line. In this way, the power supply line supplies power to the connecting wires, which in turn supply power to the conductive blocks 3 on the stator or rotor.

[0069] Existing technology uses multiple coils or a single thick flat wire protruding from both ends of the stator or rotor to electrically connect adjacent coil windings or flat wires, which wastes some coils or flat wires. This product uses connecting wires inside the end cover to power the flat wires or coils in adjacent mounting through holes and the conductive block 3. In other words, multiple coils located at both ends of the stator or rotor are connected by a single coil, saving the coils or flat wires protruding from both ends of the stator or rotor and reducing the manufacturing cost of the stator or rotor.

[0070] The end cap is also equipped with electrical connectors, which are arranged circumferentially on the cover plate. The electrical connectors are electrically connected to the flat wire or coil and the conductive block 3, and the connecting wires are electrically connected to the electrical connectors. This design is mainly to facilitate the use of flat wire motors or motors with subsequent interior flat wire motors, that is, motors that use a single wire in the stator groove, where the ends of the flat wire or coil and the conductive block 3 are directly in contact with the electrical connectors for electrical connection.

[0071] The electrical connector is a conductive cylinder, with multiple conductive cylinders evenly arranged along the axis of the cover plate. One end of each conductive cylinder is placed inside the cover plate and electrically connected to the connecting wire, while the other end of the conductive cylinder is parallel to the surface of the cover plate. This design is mainly used for flat wire motors or subsequent interior flat wire motors, that is, motors that use a single wire in the stator groove. The end of the flat wire can be directly inserted into the conductive cylinder to supply power to the flat wires in adjacent grooves.

[0072] The electrical connectors are conductive plates, with multiple conductive plates evenly arranged along the axis of the cover plate. The end faces of the conductive plates are parallel to the surface of the cover plate, and the connecting wires are electrically connected to the conductive plates. This design is mainly used for motors with coil windings, that is, motors that use multiple coils in the stator grooves. In a multi-coil winding, an electrical connection between a single coil and a conductive plate is sufficient to supply power to the coils in adjacent grooves.

[0073] The connecting wires are concealed within the cover plate, a design feature where the wires are routed according to a pre-laid layout. This design ensures a neat and aesthetically pleasing appearance at both ends of the stator or rotor. The cover plate is an insulating plate composed of GF, UP low-shrinkage additives, MD, and various auxiliaries. The cover plate allows current to flow along a specific path and also serves to extinguish arcs, dissipate heat, store energy, prevent moisture and mold, improve the potential distribution of the electric field, and protect conductors. The insulating cover plate is used to isolate the stator or rotor from the connecting wires and electrical connections.

[0074] like Figure 5 and Figure 10As shown, a generator is provided with a stator 1 and / or rotor 4 as described in this invention. The generator motor uses the stator 1 and / or rotor 4 of this invention. Insulating paper and insulating adhesive on the stator 1 and / or rotor 4 provide double-layer insulation protection for the coils or conductive blocks 3, improving the insulation isolation effect between the conductive blocks 3 and the stator and / or rotor. After the insulating adhesive, insulating paper, and stator 1 and / or rotor 4 solidify, it does not affect the subsequent removal of the coils or conductive blocks 3. That is, the flat wires and conductive blocks 3 contact the insulating paper, and the insulating paper contacts the stator 1 and / or rotor 4 through the insulating adhesive, facilitating removal.

[0075] Not shown in the diagram, each end of the stator 1 or rotor 4 has an end cover. Multiple connecting wires are installed inside the end covers, connected in series according to the generator wiring method. One end of each of the remaining wire ends is electrically connected to a conductive block 3 on the stator or rotor, while the other end is electrically connected to the outside environment. In this way, the electrical energy generated by the generator is output and used through the connecting wires.

[0076] Existing technology uses multiple coils protruding from both ends of the stator or rotor to electrically connect adjacent coil windings, which wastes some coils. This product uses connecting wires inside the end cover to power the coils or conductive blocks 3 in adjacent mounting holes. In other words, multiple coils located at both ends of the stator or rotor are connected by a single coil, saving the need for coils protruding from both ends of the stator or rotor and reducing the manufacturing cost of the stator or rotor.

[0077] The end cap is also equipped with electrical connectors, which are arranged circumferentially on the cover plate. The electrical connectors are electrically connected to the flat wire or coil and the conductive block 3, and the connecting wires are electrically connected to the electrical connectors. This design is mainly to facilitate the use of flat wire motors or motors with subsequent interior flat wire motors, that is, motors that use a single wire in the stator groove, where the ends of the flat wire or coil and the conductive block 3 are directly in contact with the electrical connectors for electrical connection.

[0078] The connecting wires are concealed within the cover plate, a design feature where the wires are routed according to a pre-laid-out circuit. This design ensures a neat and aesthetically pleasing appearance at both ends of the stator or rotor. The cover plate is an insulating plate composed of GF, UP low-shrinkage additives, MD, and various auxiliaries. The cover plate allows current to flow along a specific path and also serves to extinguish arcs, dissipate heat, store energy, prevent moisture and mold, improve the potential distribution of the electric field, and protect conductors. The insulating cover plate is used to isolate the stator or rotor from the connecting wires and electrical connections.
