Description

Technical Field

[0001] This application relates to the field of motor technology, specifically to a rotor and a synchronous reluctance motor with high heat dissipation performance. Background Technology

[0002] A synchronous reluctance motor (SRRM) is a type of motor that uses the reluctance torque generated by the difference in magnetic reluctance between the direct axis (d-axis) and the quadrature axis (q-axis) to drive the rotor and rotate the shaft. Its physical essence is that magnetic lines of force close along the path of least magnetic reluctance. The excitation magnetic field of a SRRM is generated through the stator windings; therefore, the power factor of a SRRM is lower than that of a permanent magnet motor (PMM) of the same power, and the current is also higher. For the same volume, the stator temperature rise is greater than the two types of motors mentioned above, placing higher demands on the motor's heat dissipation structure. Existing air-cooling technology has limited heat dissipation effectiveness, while liquid cooling systems suffer from the problem of excessively large pump structures that are inconvenient to install. Therefore, it is necessary to design a water pump specifically adapted to the motor to improve its heat dissipation performance while maintaining a smaller overall size.

[0003] Patent CN209908729U discloses a novel miniature diaphragm pump with a built-in one-way valve. It is compact and suitable for installation on a motor. However, it still has the following problems: it has only one umbrella head (which is actually a one-way valve) and it is directly facing the water outlet. Once the umbrella head is damaged, the one-way water outlet function will fail and the pump body will fail as a whole. Summary of the Invention

[0004] A rotor is provided with a plurality of magnetic flux barrier assemblies evenly distributed around the rotor center, each magnetic flux barrier assembly including at least two magnetic flux barriers spaced apart in the radial direction of the rotor core.

[0005] The barrier includes a bottom groove perpendicular to the Q-axis and side grooves parallel to the D-axis located on both sides of the bottom groove.

[0006] Based on the above rotor structure, this case also discloses a synchronous reluctance motor with high heat dissipation performance, including a motor body, an air cooling system disposed at the rear end of the motor body, and a liquid cooling system disposed outside the motor body.

[0007] The motor body includes at least a motor housing, a stator disposed within the motor housing, and a rotor as described in the claim rotatably disposed within the stator;

[0008] The air-cooling system includes air-cooled fan blades located at the rear end of the motor shaft and a ventilation end cover located at the rear end of the motor housing to protect the air-cooled fan blades. The ventilation end cover is densely covered with air holes.

[0009] The liquid cooling system includes a piping assembly and a drive piping assembly disposed on the outer periphery of the motor housing.

[0010] A diaphragm pump for internal coolant flow and heat sinks connected to the piping assembly;

[0011] The piping assembly includes a spiral flange formed along a spiral trajectory on the motor housing, a piping body wound around the spiral flange, and a piping sleeve disposed on the motor housing to protect the piping body.

[0012] As a further implementation, a miniature diaphragm pump more suitable for synchronous reluctance motors is proposed, the diaphragm pump including a DC motor, and further comprising:

[0013] The pump body housing includes a lower bottom shell with an opening at the upper end, a middle cylinder disposed above the lower bottom shell, and an upper cylinder formed above the middle cylinder. The middle cylinder is provided with a perforated central plate.

[0014] The extrusion assembly includes a rotating shaft driven by a DC motor, an extrusion longitudinal bar inclinedly disposed on the rotating shaft, and an extrusion lower plate vertically disposed on the extrusion longitudinal bar and corresponding to the hole position of the perforated disc.

[0015] The suction assembly includes an upper soft membrane disposed on a perforated central plate, a suction hemisphere circumferentially distributed below the upper soft membrane and passing through the perforated central plate, and a suction lower tube disposed below the suction hemisphere and passing through the perforated lower extrusion plate. The suction lower tube is also formed with an enlarged sphere at a position below the extrusion lower plate.

[0016] The valve body assembly includes a valve body base plate disposed below the inner wall of the upper cylinder, one-way inlet valves evenly distributed on the valve body base plate, and one-way outlet valves evenly distributed on the valve body base plate. The one-way inlet valves and one-way outlet valves are provided in N units and arranged at intervals between each other.

[0017] As a further implementation, N is 2, 3, or 4.

[0018] Furthermore, N is 3. That is, there are three one-way inlet valves and three one-way outlet valves. (See attached instruction manual.) Figure 6 , 7 As shown.

[0019] Thanks to the improved technical solution described above, the check valves are arranged in multiples and spaced apart on a circular trajectory. Compared with the existing technology, which has a check valve in the center and check valves evenly distributed in the other direction, the check valves in both directions are fault-tolerant. That is, when one check valve fails, the other check valves can still work normally.

[0020] Furthermore, the lower end face of the valve body substrate is also provided with a pressing upper ring for pressing the upper soft diaphragm.

[0021] An integrated end cap includes an integrated cap body with a lower opening and detachably connected to an upper cylindrical body, an isolation cylinder body in the shape of an N-angle located below the integrated cap body, a first interface located on the upper end of the integrated cap body and corresponding to the isolation cylinder body, and a second interface located on the integrated cap body outside the isolation cylinder body. The lower end of the isolation cylinder body is in sealed contact with the valve body base plate, and the isolation cylinder body is connected to all one-way inlet valves or all one-way outlet valves.

[0022] Furthermore, the integrated end cap and the upper cylindrical body are detachably connected via a locking assembly, and even further, the locking assembly includes:

[0023] The locking side is formed on the lower edge of the outer wall of the integrated cover.

[0024] The fastening assembly is circumferentially distributed on the outer wall of the upper cylindrical body, and the fastening assembly includes:

[0025] The side-mounted foundations are located on the outer wall of the upper cylinder and are arranged in pairs.

[0026] A hinged mandrel is positioned between a pair of side-mounted foundations;

[0027] A hinged swing arm is hinged to the hinged spindle, and a locking protrusion is provided at the upper end of the hinged swing arm;

[0028] A torsion spring is wound around the hinge spindle. One end of the torsion spring is fixedly connected to the hinge spindle and the other end is fixedly connected to the hinge arm. The torsion spring drives the hinge arm and the locking protrusion to swing inward and engage with the locking side.

[0029] Angle limiting assembly includes a "door" shaped groove on the outer wall of the upper cylinder and a limiting plug on the inner wall of the integrated cover that is inserted into the "door" shaped groove. The "door" shaped groove includes two longitudinal grooves and a transverse groove connected above the two longitudinal grooves. The distance between the centers of the two longitudinal grooves on the upper cylinder is (0 / N)°.

[0030] It should be noted that the upper end of the outer wall of the upper cylindrical body is provided with a sliding sealing ring that contacts the inner wall of the integrated cover.

[0031] As a further implementation, the lower end face of the integrated cover is provided with an upper sealing ring that contacts the upper end of the upper cylinder.

[0032] The upper sealing ring further enhances the sealing between the integrated cover and the upper cylinder.

[0033] As a further implementation, the lower edge of the locking side is formed with a tapered pressure surface that is wider at the top and narrower at the bottom; the hinge mandrel is formed with a driven inclined surface that mates with the tapered pressure surface.

[0034] Beneficial effects

[0035] The rotor described in this case is particularly suitable for synchronous reluctance motors.

[0036] The synchronous reluctance motor described in this case uses a dual-system cooling system—air cooling and liquid cooling—for heat dissipation. In applications with low heat dissipation requirements, only the air cooling system needs to be activated, using air-cooled fan blades for heat dissipation; in applications with high heat dissipation requirements, the liquid cooling system also needs to be activated.

[0037] The synchronous reluctance motor described in this case has a small-sized diaphragm pump in its liquid cooling system, which can be directly installed on the motor housing.

[0038] The synchronous reluctance motor described in this case has multiple one-way inlet and one-way outlet valves evenly distributed around its circumference in a spaced-apart manner with the diaphragm pump. Compared to the prior art, which has a central one-way valve and multiple reverse one-way valves evenly distributed around its circumference, the one-way valves in both directions are fault-tolerant, meaning that if one one-way valve fails, the others can still function normally.

[0039] The synchronous reluctance motor described in this case has an integrated end cap isolation cylinder that can realize the function of water inlet and water outlet partitioning, and can switch between water inlet and water outlet: for example, when the number of one-way water inlet valves or one-way water outlet valves N=3, rotating 60° can switch the isolation cylinder 62 from the state connected to the one-way water inlet valve 52 to the state connected to the one-way water outlet valve 53, thus completing the switching of water inlet and water outlet directions.

[0065] A rotor is provided with a plurality of magnetic flux barrier assemblies evenly distributed around the rotor center, each magnetic flux barrier assembly including at least two magnetic flux barriers spaced apart in the radial direction of the rotor core.

[0066] The barrier includes a bottom groove perpendicular to the Q-axis and side grooves parallel to the D-axis located on both sides of the bottom groove.

[0067] Based on the above rotor structure, this case also discloses a synchronous reluctance motor with high heat dissipation performance, including a motor body a, an air cooling system b disposed at the rear end of the motor body a, and a liquid cooling system c disposed outside the motor body a.

[0068] The motor body a includes at least a motor housing a1, a stator a2 disposed within the motor housing a1, and a rotor a3 as described in claim 1, which is rotatably disposed within the stator a2;

[0069] The air-cooling system b includes an air-cooled fan blade b1 located at the rear end of the motor shaft and a ventilation end cover b2 located at the rear end of the motor housing a1 to protect the air-cooled fan blade b1. The ventilation end cover b2 is densely covered with air holes.

[0070] The liquid cooling system c includes a piping assembly c1 disposed on the outer periphery of the motor housing a1 and a drive piping assembly c1.

[0071] Diaphragm pump c2 for internal coolant flow, and heat sink c3 connected to piping assembly c1;

[0072] The piping assembly c1 includes a spiral flange c11 formed along a spiral trajectory on the motor housing a1, a piping body c12 wound around the spiral flange c11, and a piping sleeve c13 disposed on the motor housing a1 to protect the piping body c12.

[0073] As a further implementation, a miniature diaphragm pump c2 more suitable for synchronous reluctance motors is proposed. The diaphragm pump c2 includes a DC motor 1 and further includes:

[0074] The pump body housing 2 includes a lower bottom shell 21 with an upper opening, a middle cylinder 22 disposed above the lower bottom shell 21, and an upper cylinder 23 formed above the middle cylinder 22. The middle cylinder 22 is provided with a perforated central plate 22a.

[0075] The extrusion assembly 3 includes a rotating shaft 31 driven by a DC motor 1, an extrusion longitudinal rod 32 inclinedly disposed on the rotating shaft 31, and an extrusion lower platen 33 vertically disposed on the extrusion longitudinal rod 32 and corresponding to the hole position of the perforated middle plate 22a.

[0076] The suction assembly 4 includes an upper soft membrane 41 disposed on a perforated central plate 22a, suction hemispheres 42 circumferentially distributed below the upper soft membrane 41 and passing through the holes of the perforated central plate 22a, and suction lower tube 43 disposed below the suction hemispheres 42 and passing through the holes of the extrusion lower plate 33. The suction lower tube 43 is also formed with an enlarged sphere 44 at a position below the extrusion lower plate 33.

[0077] The valve body assembly 5 includes a valve body base plate 51 disposed below the inner wall of the upper cylindrical body 23, one-way inlet valves 52 evenly distributed on the valve body base plate 51, and one-way outlet valves 53 evenly distributed on the valve body base plate 51. The one-way inlet valves 52 and one-way outlet valves 53 are provided in N units and arranged at intervals between each other.

[0078] As a further implementation, N is 2, 3, or 4.

[0079] Furthermore, N is 3. That is, there are three of each of the one-way inlet valve 52 and one-way outlet valve 53. (See attached instruction manual.) Figure 6 , 7 As shown.

[0080] Thanks to the improved technical solution described above, the check valves are arranged in multiples and spaced apart on a circular trajectory. Compared with the existing technology, which has a check valve in the center and check valves evenly distributed in the other direction, the check valves in both directions are fault-tolerant. That is, when one check valve fails, the other check valves can still work normally.

[0081] As a further implementation plan:

[0082] The lower end face of the valve body base plate 51 is also provided with a pressing upper ring 54 for pressing the upper soft membrane 41.

[0083] Thanks to the aforementioned compression ring 54, a seal can be achieved between the upper cylinder 23 and the middle cylinder 22.

[0084] The integrated end cap 6 includes an integrated cap body 61 with a lower opening and detachably connected to the upper cylindrical body 23, an isolation cylindrical body 62 with an N-shaped angular shape located below the integrated cap body 61, a first interface 63 located on the upper end of the integrated cap body 61 and corresponding to the isolation cylindrical body 62, and a second interface 64 located on the integrated cap body 61 outside the isolation cylindrical body 62. The lower end of the isolation cylindrical body 62 is in sealed contact with the valve body base plate 51, and the isolation cylindrical body 62 is connected to all one-way inlet valves 52 or all one-way outlet valves 53.

[0085] Thanks to the improved technical solution described above, the integrated end cap 6 has the function of separating water inlet and outlet:

[0086] When the isolation cylinder 62 is connected to all one-way inlet valves 52, refer to the attached instruction manual. Figure 6 As shown, at this time, the first interface 63 connected to the isolation cylinder 62 essentially becomes a one-way water inlet, while the second interface 64 located outside the isolation cylinder 62 essentially becomes a one-way water outlet.

[0087] As a further implementation plan:

[0088] The integrated end cap 6 and the upper cylindrical body 23 are detachably connected via a locking assembly 7. Furthermore, the locking assembly 7 includes:

[0089] Locking side 71 is formed on the lower edge of the outer wall of the integrated cover 61;

[0090] The fastening assembly 72 is circumferentially distributed on the outer wall of the upper cylindrical body 23, and the fastening assembly 72 includes:

[0091] Side-mounted foundations 72a are provided on the outer wall of the upper cylindrical body 23 and are arranged in pairs;

[0092] A hinged mandrel 72b is disposed between a pair of side-mounted bases 72a;

[0093] A hinged swing arm 72c is hinged to the hinged spindle 72b, and a locking protrusion 72d is provided at the upper end of the hinged swing arm 72c;

[0094] A torsion spring 72e is wound around the hinge spindle 72b. One end of the torsion spring 72e is fixedly connected to the hinge spindle 72b and the other end is fixedly connected to the hinge arm 72c. The torsion spring 72e drives the hinge arm 72c and the locking protrusion 72d to swing inward and engage with the locking side 71.

[0095] The angle limiting assembly 73 includes a "door" shaped groove 73a provided on the outer wall of the upper cylindrical body 23 and a limiting plug 73b provided on the inner wall of the integrated cover 61 and inserted into the "door" shaped groove 73a. The "door" shaped groove 73a includes two longitudinal grooves and a transverse groove connected above the two longitudinal grooves. The distance between the centers of the two longitudinal grooves on the upper cylindrical body 23 is (360 / 2N)°.

[0096] It should be noted that the upper end of the outer wall of the upper cylindrical body 23 is provided with a sliding sealing ring 74 that contacts the inner wall of the integrated cover 61.

[0097] Thanks to the improved technical solution described above, when the integrated cover 61 slides and rotates on the upper cylinder 23, the sliding sealing ring 74 can still achieve a seal between the upper cylinder 23 and the integrated cover 61.

[0098] As a further implementation, the lower end face of the integrated cover 61 is provided with an upper sealing ring 75 that contacts the upper end of the upper cylinder 23.

[0099] The upper sealing ring 75 further enhances the sealing degree between the integrated cover 61 and the upper cylinder 23.

[0100] As a further implementation plan:

[0101] The lower edge of the locking side 71 is formed with a tapered pressing surface that is wider at the top and narrower at the bottom;

[0102] The hinged mandrel 72d is formed with a driven inclined surface that mates with the tapered pressure surface.

[0103] The synchronous reluctance motor with high heat dissipation performance has a diaphragm pump inlet and outlet in its liquid cooling system that can be quickly adjusted. The adjustment method is as follows:

[0104] Step 1, unlock integrated end cap 6:

[0105] Move the hinge arm 72c and locking lug 72d to make it rotate outward against the damping of the torsion spring 72e;

[0106] Repeat the above steps to pry all the fastened assemblies 72 outwards in sequence;

[0107] At this time, the fastening assembly 72 no longer fastens the locking side 71, and the integrated end cover 6 is able to unlock its longitudinal sliding freedom.

[0108] Step 2, rotate to the specified angle:

[0109] Step 2.1, push the integrated end cover 6 upward to move the limit plug 73b upward, and slide it from the bottom of the longitudinal groove of the "door" shaped groove to the top. At this time, release the fastening assembly 72 to reset it.

[0110] As per the instruction manual Figure 11 As shown, this step facilitates the separation of the isolation cylinder 62 of the integrated end cap 6 from the valve body base plate 51, thereby facilitating the next rotation operation.

[0111] Step 2.2, then rotate the integrated end cover 6 to drive the limit plug 73b to rotate and slide from one side of the transverse groove of the "door" shaped groove to the other side;

[0112] As per the instruction manual Figure 12 As shown, this step allows the integrated end cap 6 and the isolation cylinder 62 to rotate at an appropriate angle. This angle is the angle between the centers of the two longitudinal grooves on the upper cylinder 23, which is (360 / 2N)°. When N = 3, it is a rotation of 60°, allowing the isolation cylinder 62 to rotate from the end cap 6 to the center of the cylinder 23. Figure 7 The state shown in the diagram, where the one-way inlet valve 52 is connected, is switched to the state indicated in the instruction manual. Figure 8 The state described above, which is connected to the one-way outlet valve 53, completes the switching of the water inlet and outlet directions.

[0113] Step 2.3, then press down the integrated end cover 6, causing the limit plug 73b to move down and slide down from the upper end of the other longitudinal groove of the "door" shaped groove to the bottom;

[0114] As per the instruction manual Figure 13 As shown, this step is to facilitate the re-fixing of the integrated end cap 6 onto the upper cylinder 23.

[0115] Step 3, Lock the integrated end cap:

[0116] During the downward movement of the integrated end cap 6, the tapered pressing surface of the locking side 71 presses down on the driven inclined surface of the locking protrusion 72d, causing it to rotate outward against the damping of the torsion spring 72e, until the locking side 71 passes the locking protrusion 72d and is locked by it.

[0117] Thanks to the improved technical solution described above, the locking assembly 7 can achieve sealing and allow a fixed angle rotation between the integrated end cap 6 and the upper cylinder 23, thereby facilitating the isolation cylinder 62 to select and switch between the one-way inlet valve 52 and the one-way outlet valve 53.

[0118] It should be noted that the outer wall of the upper cylindrical body 23 is evenly distributed with limiting blocks 72f that abut against the inner side of the hinged swing arm 72c. The limiting blocks 72f ensure that the hinged swing arm 72c and the hinged spindle 72d remain in a vertical position under normal conditions. This allows the tapered pressing surface of the locking side 71 to effectively squeeze the driven inclined surface of the limiting block 72d when it is pressed down, causing it to fold outward. This prevents the hinged spindle 72d from folding inward too much, which would cause the flat surfaces of the locking side 71 and the limiting block 72d to come into contact, making it impossible to squeeze the limiting block 72d to fold outward.

[0119] It should be noted that the isolation cylinder 62 includes N outwardly protruding arc-shaped protrusions 62a for surrounding the one-way inlet valve 52 (or one-way outlet valve 53) and inwardly recessed recesses 62b connecting adjacent protrusions 62a. The recesses 62b are used to exclude the one-way outlet valve 53 (or one-way inlet valve 52) from the enclosure.
