[0044] The embodiments of the present application provide a magnetic levitation linear motor, which can drive an external device to perform linear motion and can be applied to various processing equipment.

[0045] Figure 1 A schematic diagram of the structure of a magnetic levitation linear motor provided in one embodiment of the present application. Figure 2 A schematic structural diagram of a mover of a magnetic levitation linear motor provided in one embodiment of the present application. Figure 3 This is a schematic diagram of the structure of the stator of a magnetic suspension linear motor provided in one embodiment of the present application. Figures 1 to 3 The magnetic suspension linear motor provided in the embodiment of the present application includes a mover 100, a stator 200, a magnetic attraction component 7, a first magnetic conductive component 8, and a coil winding 10.

[0046] The mover 100 comprises a non-magnetic mover housing 1 and a magnetic mover pole.

[0047] The mover 100 can move along a defined path relative to the stator 200 .

[0048] The non-magnetic conductive rotor housing 1 is a frame structure of the rotor 100. The non-magnetic conductive rotor housing 1 is a housing made of non-magnetic conductive material and is basically not magnetized.

[0049] The aforementioned non-magnetic conductive material may specifically be a non-magnetic conductive metal material or a non-metallic material; the aforementioned non-magnetic conductive metal material may specifically be aluminum or copper, etc.; the aforementioned non-metallic material may specifically be plastic or ceramic, etc.

[0050] The shape of the non-magnetic conductive mover housing 1 can be arc-shaped to reduce wind resistance. Of course, according to actual needs, the shape of the non-magnetic conductive mover housing 1 can also be triangular or square.

[0051] The movable magnetic poles can be magnetized. The movable magnetic poles 3 can be iron cores or other iron-based soft magnetic components.

[0052] The mover magnetic conductive poles 3 are arranged in the non-magnetic conductive mover housing 1 .

[0053] The number of the movable magnetizing poles can be one or more. When the number of the movable magnetizing poles is multiple (such as two, three, or four, etc.), they are divided into a first movable magnetizing pole 2 and a second movable magnetizing pole 3.

[0054] For example, the first mover magnetic conductive magnetic pole 2 is arranged on one side of the non-magnetic conductive mover housing 1, and the second mover magnetic conductive magnetic pole 3 is arranged on the other side of the non-magnetic conductive mover housing 1. If the number of the mover magnetic conductive magnetic poles is three or four, the mover magnetic conductive magnetic poles can be distributed in a circular array with the central axis of the non-magnetic conductive mover housing 1 as the center.

[0055] The stator 200 includes a non-magnetic stator support 4 and a stator magnetic pole.

[0056] The non-magnetic stator bracket 4 is a frame structure of the stator 200. The non-magnetic stator bracket 4 is a structure made of non-magnetic material and is basically not magnetized.

[0057] The stator magnetic conductive poles can be magnetized. The stator magnetic conductive poles can specifically be iron cores or other iron-based soft magnetic components.

[0058] The stator magnetic poles are arranged on the non-magnetic stator bracket 4 .

[0059] The number of the stator magnetic conductive poles may be one or more. When the number of the stator magnetic conductive poles is multiple (such as two, three, or four, etc.), it may include a first stator magnetic conductive pole 5 and a second stator magnetic conductive pole 6.

[0060] For example, the first stator magnetic conductive pole 5 is arranged on one side of the non-magnetic conductive stator bracket 4, and the second stator magnetic conductive pole 6 is arranged on the other side of the non-magnetic conductive stator bracket 4. If the number of the stator magnetic conductive poles is three or four, the stator magnetic conductive poles can be specifically distributed in a circular array with the central axis of the non-magnetic conductive stator bracket 4 as the center.

[0061] The magnetic attraction component 7 can attract other components through a magnetic field. The magnetic attraction component 7 can be a permanent magnet or an electromagnet. Among them, the electromagnet will generate a magnetic field after being energized, thereby attracting other components.

[0062] The first magnetic conductive component 8 is a component that can be magnetized and can be an iron core or other iron-based soft magnetic components.

[0063] One of the magnetic attraction component 7 and the first magnetic conductive component 8 is disposed on the non-magnetic conductive rotor housing 1, and the other is disposed on the non-magnetic conductive stator bracket 4. The rotor 100 can move relative to the stator 200, and the non-magnetic conductive rotor housing 1 of the rotor 100 can also move relative to the non-magnetic conductive stator bracket 4 of the stator 200, and the magnetic attraction component 7 and the first magnetic conductive component 8 can also move relative to each other.

[0064] During the relative movement between the magnetic attraction component 7 and the first magnetic conductive component 8 , the magnetic attraction component 7 and the first magnetic conductive component 8 can move to face each other in the height direction H of the magnetic suspension linear motor.

[0065] In the height direction H of the magnetic levitation linear motor, there is an air gap between the first magnetic conductive component 8 and the magnetic attraction component 7 and the first magnetic conductive component 8 can be directly opposite to the magnetic attraction component 7, so that suction is generated between the first magnetic conductive component 8 and the magnetic attraction component 7 and they attract each other, thereby generating suction between the mover 100 and the stator 200 and they attract each other.

[0066] The coil winding is wound around the stator magnetic pole or the mover magnetic pole. When the coil winding is energized, the stator magnetic pole or the mover magnetic pole will be magnetized.

[0067] The number of the coil windings may be one or more. When the number of the coil windings is multiple (such as two, three, or four, etc.), a first coil winding 9 and a second coil winding 10 may be included.

[0068] The first coil winding 9 is wound around the first stator magnetizing pole 5 or the first mover magnetizing pole 2. When the first coil winding 9 is energized, the first stator magnetizing pole 5 or the first mover magnetizing pole 2 will be magnetized.

[0069] The second coil winding 10 is wound around the second stator magnetizing pole 6 or the second mover magnetizing pole 3. When the second coil winding 10 is energized, the second stator magnetizing pole 6 or the second mover magnetizing pole 3 is magnetized.

[0070] In the height direction H, the mover magnetic pole can face the stator magnetic pole with an air gap. For example, the first mover magnetic pole 2 can face the first stator magnetic pole 5, and the second mover magnetic pole 3 can face the second stator magnetic pole 6.

[0071] In the aforementioned height direction H, when the first movable magnetic pole 2 is directly opposite to the first stator magnetic pole 5, there is an air gap between the first movable magnetic pole 2 and the first stator magnetic pole 5; under the action of the first coil winding 9, the first movable magnetic pole 2 and the first stator magnetic pole 5 are magnetized; when the second movable magnetic pole 3 is directly opposite to the second stator magnetic pole 6, there is an air gap between the second movable magnetic pole 3 and the second stator magnetic pole 6; under the action of the second coil winding 10, the second movable magnetic pole 3 and the second stator magnetic pole 6 are magnetized.

[0072] The direction of the force applied by the magnetic component 7 and the first magnetic component 8 to the non-magnetic rotor housing 1 (i.e., the pulling force applied to the non-magnetic rotor housing 1 by the mutual attraction between the magnetic component 7 and the first magnetic component 8) is opposite to the direction of the force applied by the rotor's magnetic poles and the stator's magnetic poles to the non-magnetic rotor housing 1 (i.e., the pulling force applied to the non-magnetic rotor housing 1 by the mutual attraction between the rotor's magnetic poles and the stator's magnetic poles). In this way, the electromagnetic attraction between the rotor's magnetic poles and the stator's magnetic poles can overcome the attraction between the magnetic component 7 and the first magnetic component 8, so that the gravity of the rotor 100, the electromagnetic attraction, and the attraction between the magnetic component 7 and the first magnetic component 8 are balanced, thereby achieving suspension of the rotor 100.

[0073] The first rotor magnetic pole 2 is arranged on one side of the non-magnetic rotor housing 1, the second rotor magnetic pole 3 is arranged on the other side of the non-magnetic rotor housing 1, the first stator magnetic pole 5 is arranged on one side of the non-magnetic stator bracket 4, and the second stator magnetic pole 6 is arranged on the other side of the non-magnetic stator bracket 4. The rotor magnetic pole and the stator magnetic pole can be directly opposite to each other, so that the electromagnetic attraction of the poles on both sides is symmetrical about the central axis of the magnetic levitation motor, which can facilitate the suspension of the rotor 100.

[0074] According to the above content, as the mover 100 moves relative to the stator 200, in the height direction H of the magnetic suspension linear motor, the magnetic attraction component 7 will be opposite to the first magnetic conductive component 8, the first mover magnetic conductive magnetic pole 2 of the mover 100 will also be opposite to the first stator magnetic conductive magnetic pole 5 of the stator 200, and the second mover magnetic conductive magnetic pole 3 of the mover 100 will also be opposite to the second stator magnetic conductive magnetic pole 6 of the stator 200, and an attraction force will be generated between the magnetic attraction component 7 and the first magnetic conductive component 8, and the first coil winding 9 and the second coil winding 10 will be energized, so that the first mover magnetic conductive magnetic pole 2 of the mover 100 and the first stator magnetic conductive magnetic pole 5 of the stator 200 will be opposite to each other. A magnetic circuit is formed between the stator magnetic poles 5 and an electromagnetic attraction is generated, and a magnetic circuit is formed between the second mover magnetic pole 3 of the mover 100 and the second stator magnetic pole 6 of the stator 200 and an electromagnetic attraction is generated. The electromagnetic attraction can overcome the attraction between the magnetic component 7 and the first magnetic component 8 to achieve suspension of the mover 100. The suspension force can be changed by changing the current of the first coil winding 9 and the second coil winding 10, so that the air gap between the magnetic component 7 and the first magnetic component 8 can be adjusted, thereby achieving stable tension output control of the linear motor and stable tension output.

[0075] refer to Figure 1 If the magnetic attraction component 7 is arranged on the non-magnetic rotor shell 1 of the mover 100, in the aforementioned height direction, there is a certain distance between the magnetic attraction component 7 and the magnetic poles (such as the first mover magnetic pole 2 and the second mover magnetic pole 3), and they are connected through the non-magnetic rotor shell 1, which can reduce the magnetic circuit coupling. Figure 4 A magnetic density cloud diagram of a state of a magnetic suspension linear motor provided by an embodiment of the present application. Figure 4 Through the analysis of the magnetic density cloud map, the coupling between the magnetic circuit above the magnetic levitation motor provided by the embodiment of the present application (including the magnetic circuit formed by the magnetic attraction component 7 and the first magnetic conductive component 8) and the magnetic circuit formed by the magnetic poles on both sides (including the magnetic circuit formed by the first movable magnetic pole 2 and the first stator magnetic conductive pole 5, and the magnetic circuit formed by the second movable magnetic pole 3 and the second stator magnetic conductive pole 6) is very small, which is conducive to the decoupling and precise control of the levitation force.

[0076] Figure 5 A magnetic density cloud diagram of another state of a magnetic suspension linear motor provided by an embodiment of the present application. Figure 5 When the mover 100 is displaced to the left, the magnetic poles of the magnetic suspension linear motor will generate a rightward magnetic pulling force, causing the mover 100 to return to the center position. Figure 6 This is a magnetic density cloud diagram of another state of the magnetic suspension linear motor provided by an embodiment of the present application. Figure 6 When the mover 100 of the magnetic levitation linear motor is displaced to the right, the magnetic poles of the magnetic levitation linear motor will generate a leftward magnetic pulling force, so that the mover 100 returns to the center position, thereby realizing the left and right passive suspension of the magnetic levitation linear motor and keeping the output pulling force basically stable.

[0077] refer to Figure 1 The above-mentioned magnetic levitation linear motor may further include a second magnetic conductive component 11.

[0078] The second magnetic conductive component 11 is a component that can be magnetized and can be an iron core or other iron-based soft magnetic components.

[0079] The second magnetic conductive component 11 is connected to the magnetic attraction component 7 so as to install the magnetic attraction component 7 on the non-magnetic conductive mover housing 1 or the non-magnetic conductive stator bracket 4 .

[0080] Since the magnetic attraction component 7 can attract other components through the magnetic field, the second magnetic conductive component 11 is specifically connected to the magnetic attraction component 7 through magnetic attraction. Specifically, the second magnetic conductive component 11 is fixedly installed on the non-magnetic conductive rotor housing 1 or the non-magnetic conductive stator bracket 4, and the magnetic attraction component 7 attracts the second magnetic conductive component 11 through magnetic attraction and is fixed to the second magnetic conductive component 11.

[0081] The second magnetic conductive component 11 can be specifically disposed in the middle of the inner top of the non-magnetic conductive mover housing 1 , or in the middle of the outer top of the non-magnetic conductive mover housing 1 .

[0082] As mentioned above, the magnetic attraction component 7 can be a permanent magnet or an electromagnet. If the magnetic attraction component 7 is disposed in the non-magnetic rotor housing 1, it can move with the rotor 100 relative to the stator 200. The first magnetic conductive component 11 is disposed in the non-magnetic stator bracket 4.

[0083] When the magnetic attraction component 7 is a permanent magnet, the magnetic attraction component 7 is arranged on the non-magnetic conductive rotor housing 1 and moves with the rotor 100 relative to the stator 200. It is only necessary to install the permanent magnet on the rotor 100, which can reduce the number of permanent magnets used.

[0084] refer to Figure 1 The first coil winding 9 is wound around the first stator magnetic pole 5, and the second coil winding 10 is wound around the second stator magnetic pole 6 (i.e., the coil winding is wound around the stator magnetic pole), which can achieve the first coil winding 9 and the second coil winding 10 being stationary relative to the non-magnetic stator bracket 4, making it convenient to supply power to the first coil winding 9 and the second coil winding 10 and simplifying the structure.

[0085] refer to Figure 1 In the width direction W of the magnetic suspension linear motor, the width of the magnetic attraction component 7 is greater than the width of the first magnetic conductive component 11.

[0086] As mentioned above, one of the magnetic attraction component 7 and the first magnetic conductive component 8 is arranged on the non-magnetic rotor housing 1 of the mover 100, and the other is arranged on the non-magnetic stator bracket 4 of the stator 200; in the width direction of the magnetic levitation linear motor, since the width of the magnetic attraction component 7 is greater than the width of the first magnetic conductive component 11 between the mover 100 and the stator 200 of the motor, when the mover 100 of the magnetic levitation linear motor is displaced left and right, the part of the width of the magnetic attraction component 7 that is greater than the width of the first magnetic conductive component 11 is greater than the left and right displacement value of the mover 100, and the effective length of the magnetic levitation linear motor remains basically unchanged, which can make the output of the magnetic levitation motor relatively stable.

[0087] refer to Figure 1 In some embodiments, the stator magnetic poles are located inside the non-magnetic rotor housing 1, for example, the first stator magnetic poles 5 and the second stator magnetic poles 6 are located inside the non-magnetic rotor housing 1, which can fully utilize the internal space of the non-magnetic rotor housing 1.

[0088] refer to Figure 1 In some embodiments, the mover magnetic conductive poles are arranged inside the non-magnetic mover housing 1, for example, the first mover magnetic conductive poles 2 are arranged on one side inside the non-magnetic mover housing 1, and the second mover magnetic conductive poles 3 are arranged on the other side inside the non-magnetic mover housing 1. In this way, the mover magnetic conductive poles and the stator magnetic conductive poles are located inside the non-magnetic mover housing 1, which can reduce the wind resistance of the mover 100.

[0089] refer to Figure 1 In the aforementioned height direction H, the top angles of the stator magnetizing poles are rounded, for example, the top angles of the first stator magnetizing pole 5 and the second stator magnetizing pole 6 are rounded.

[0090] refer to Figure 1 In some embodiments, the top angle of the stator magnetic pole can support the inner side surface of the non-magnetic rotor housing 1, for example: the top angle of the first stator magnetic pole 5 can support the inner side surface of one side of the non-magnetic rotor housing 1, and the top angle of the second stator magnetic pole 6 can support the inner side surface of the other side of the non-magnetic rotor housing 1; the inner side surface of the non-magnetic rotor housing 1 is an arc surface, for example: the inner side surface of one side and the inner side surface of the other side of the non-magnetic rotor housing 1 are arc surfaces.

[0091] The inner side surface of the non-magnetic rotor housing 1 is an arc surface, which is relatively smooth, and can facilitate the rounded vertices of the first stator magnetic pole 5 and the second stator magnetic pole 6 to support the entire non-magnetic rotor housing 1 (for example, supporting the entire non-magnetic rotor housing 1 in a non-magnetic suspension state), and the rounded corners can increase the support area of ​​the arc surface on the inner side of the non-magnetic rotor housing 1, which can prevent damage to the non-magnetic rotor housing 1 and the magnetic poles, and can protect the non-magnetic rotor housing 1 and the magnetic poles.

[0092] refer to Figure 1In some embodiments, the first mover magnetic conductive pole 2 and the second mover magnetic conductive pole 3 are U-shaped structures; the first stator magnetic conductive pole 5 and the second stator magnetic conductive pole 6 are U-shaped structures.

[0093] In the aforementioned width direction H, the first coil winding 9 is wound around the portion of the first stator magnetic pole 5 close to the non-magnetic stator bracket 4 , and the second coil winding 10 is wound around the portion of the second stator magnetic pole 6 close to the non-magnetic stator bracket 4 .

[0094] The first stator magnetic pole 5 and the second stator magnetic pole 6 are U-shaped structures. The part of the first stator magnetic pole 5 close to the non-magnetic stator bracket 4 has a relatively large space, which can facilitate the installation of each coil winding, prevent the friction damage of each coil winding and cause insulation damage, and better protect each coil winding.

[0095] The magnetic levitation linear motor provided in the embodiment of the present application can achieve stable tension output control of the linear motor, can achieve stable tension output, can reduce magnetic circuit coupling, can achieve decoupling and precise control of the levitation force, and can ensure stable motor output.

[0096] The embodiment of the present application further provides a processing device, which includes the magnetic suspension linear motor provided by any of the above embodiments. The processing device can specifically be a laser processing device or a machining device.

[0097] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
