Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to an asynchronous self-starting permanent magnet synchronous reluctance flat wire motor with a high protection level. Background Art

[0002] Driven by the rapid development of new energy vehicles, industrial automation and many other fields, flat wire motors have been widely used due to their significant advantages such as high power density and high efficiency.

[0003] Flat wire motors use flat wire windings, which improve the slot fill rate compared to traditional round wire motors, thereby improving the output power and efficiency of the motor.

[0004] For example, a Chinese patent with announcement number CN221900625U discloses a stator of a flat wire motor and a flat wire motor, including a stator core and a flat wire winding, the flat wire winding having a three-phase winding, the number of poles of the flat wire winding being 8, the number of winding slots per pole per phase of the stator core being 2, the number of layers L formed by the flat wire winding in the winding slot being an even number greater than 2, and in each pole per phase, the slots occupied by the flat wire winding include two inner slots continuous in the circumferential direction and two outer slots continuous in the circumferential direction, the inner slots are occupied by the corresponding windings in the L / 2 layers located radially inward, the outer slots are occupied by the corresponding windings in the L / 2 layers located radially outward, and the inner slots and the outer slots are staggered by 2 slot positions in the circumferential direction.

[0005] The above flat wire motor solves some defects of the prior art, but there are still some shortcomings in the use process, such as:

[0006] As the power density of flat wire motors continues to increase, the heat generated during their operation is also increasing. If the excessive heat cannot be dissipated in a timely and effective manner, the motor temperature will rise sharply.

[0007] On the one hand, excessively high temperatures can reduce the insulation performance of the motor windings, shorten the motor's service life, and may even cause serious faults such as insulation breakdown, affecting the motor's reliability and safety. For example, in the frequent start-stop and high-speed driving conditions of new energy vehicles, flat wire motors run at high loads for a long time. If a large amount of heat is generated and accumulated inside the motor, it will accelerate the aging of the insulation material.

[0008] On the other hand, the increase in temperature will also cause the motor's magnetic steel performance to decline, reducing the motor's torque output capacity and affecting the motor's performance. For example, in industrial automation equipment, when the motor temperature is too high, the stability of its speed and torque will be affected, resulting in a decrease in the equipment's operating accuracy.

[0041] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0042] Please refer to Figures 1 to 9 As shown, an embodiment of the present invention provides an asynchronous self-starting permanent magnet synchronous reluctance flat wire motor with a high protection level, including a housing 1, a front cover 2, a rear cover 3, a rotating shaft 4, a rotor 5 and a stator. The stator includes a stator core 6 and a flat wire winding. A winding groove 603 is opened on the stator core 6. A plurality of winding grooves 603 are provided. The plurality of winding grooves 603 are distributed on the inner wall of the stator core 6 in an annular equidistant array. The flat wire winding is installed in the winding groove 603. The winding method of the flat wire winding in this embodiment adopts the winding method disclosed in the prior art, which will not be described in detail here. The stator core 6 is fixedly installed in the inner wall of the housing 1. The front cover 2 is fixedly mounted on one end of the outer shell 1, the rear cover 3 is fixedly mounted on the end of the outer shell 1 away from the front cover 2, the shaft 4 is rotatably arranged inside the stator, the rotor 5 is fixedly mounted on the shaft 4, one end of the shaft 4 is rotatably penetrated through the front cover 2 through a first bearing, the other end of the shaft 4 is rotatably arranged on the rear cover 3 through a second bearing, a plurality of heat dissipation channels are provided on the stator core 6, the heat dissipation channels are spaced apart from the winding grooves 603, a liquid inlet 604 connected to the heat dissipation channel is provided on the side surface of one end of the stator core 6, and a liquid outlet 605 connected to the heat dissipation channel is provided on the side surface of the other end of the stator core 6.

[0043] By directly opening a heat dissipation channel on the stator core 6, the coolant can directly contact the stator core 6, quickly take away the heat, and quickly dissipate the heat to the outside, effectively avoiding the motor from overheating and causing performance degradation and component damage, greatly improving the heat dissipation efficiency and stability of the motor, and setting the liquid inlet 604 and the liquid outlet 605 of the heat dissipation channel on the side of the stator core 6, which not only ensures the stable circulation of the coolant for heat dissipation, but also does not interfere with the installation of the flat wire winding, ensuring the compactness of the motor structure and the effectiveness of the heat dissipation system.

[0044] In this embodiment, the stator core 6 includes a main housing 601, the inner wall of the main housing 601 is provided with a first through slot 6001, the main housing 601 is provided with through holes 6002, the through holes 6002 and the first through slots 6001 are alternately distributed, a first assembly part is fixedly installed at one end of the main housing 601, and a second assembly part is fixedly installed at the other end of the main housing 601;

[0045] The first assembly part and the second assembly part both include an annular part 602, the inner wall of the annular part 602 is provided with a second through groove 6021, the annular part 602 is provided with an arc-shaped channel 6022, and the arc-shaped channel 6022 and the second through groove 6021 are alternately distributed;

[0046] The second through slot 6021 on the first assembly part, the second through slot 6021 on the second assembly part and the first through slot 6001 on the main housing 601 form a winding slot 603;

[0047] The arc-shaped channel 6022 on the first assembly part, the arc-shaped channel 6022 on the second assembly part and the through hole 6002 form a heat dissipation channel.

[0048] The stator core 6 formed by adopting the above technical solution adopts the structure of the main housing 601 with the first assembly and the second assembly, and the second through slot 6021 on the first assembly, the second through slot 6021 on the second assembly and the first through slot 6001 on the main housing 601 cooperate with each other to form a complete winding slot 603. The winding slot 603 provides an accurate and stable space for the installation of the flat wire winding, ensuring that the flat wire winding can be arranged neatly and orderly, thereby ensuring the high efficiency of the electromagnetic conversion of the motor. The arc channel 6022 on the first assembly, the arc channel 6022 on the second assembly and the through hole 6002 on the main housing 601 are combined to form a heat dissipation channel. The heat dissipation channel provides a special path for the flow of the coolant, which can promptly take away the heat generated during the operation of the motor, and ensure that the motor runs stably under a suitable temperature environment. The modular structure of the main housing 601 with the first assembly and the second assembly greatly facilitates the production and assembly of the motor.

[0049] In this embodiment, a first annular groove 101 and a second annular groove 102 are respectively provided at both ends of the shell 1, the liquid outlet 605 is located on the inner side of the first annular groove 101, and the liquid inlet 604 is located on the inner side of the second annular groove 102. A first liquid collecting groove 103 is formed at the bottom of one end of the shell 1, and the first liquid collecting groove 103 is connected to the second annular groove 102. A second liquid collecting groove 104 is formed at the bottom of the other end of the shell 1, and the second liquid collecting groove 104 is connected to the first annular groove 101. One side of the first liquid collecting groove 103 is connected to a liquid inlet pipe 1031, and one side of the second liquid collecting groove 104 is connected to a liquid outlet pipe 1041.

[0050] Through the above arrangement, the coolant can circulate in an orderly manner inside the motor. Specifically, the second annular groove 102 cooperates with the first liquid collecting tank 103 and the liquid inlet pipe 1031 to form an input channel for the coolant. The external coolant can flow into the first liquid collecting tank 103 along the liquid inlet pipe 1031, and after a short collection and buffering in the first liquid collecting tank 103, it is smoothly introduced into the liquid inlet 604 through the second annular groove 102. After the coolant enters the liquid inlet 604, it begins to flow in the heat dissipation channel of the stator core 6. In this process, the coolant fully absorbs the heat generated by the operation of the motor to achieve effective cooling of the motor.

[0051] After completing the heat dissipation task, the coolant will flow out from the liquid outlet 605 and enter the first annular groove 101. The first annular groove 101 plays a role of transition and guidance, and introduces the coolant into the second liquid collecting tank 104 connected thereto. Finally, the coolant flows out of the motor from the second liquid collecting tank 104 through the liquid outlet pipe 1041, completing the entire coolant circulation process. The design of this coolant circulation system ensures that the motor can dissipate heat in a timely and effective manner and maintain a stable operating temperature, thereby ensuring the performance and reliability of the motor.

[0052] In this embodiment, annular sealing grooves 105 are provided on both sides of the first annular groove 101 and on both sides of the second annular groove 102, and an annular sealing ring 106 is installed inside the annular sealing groove 105, and the inner ring of the annular sealing ring 106 is in sealed contact with the outer wall of the annular member 602. A complete sealing system is constructed through the coordinated cooperation of the annular sealing groove 105 and the annular sealing ring 106. This system can reliably seal the coolant in the first annular groove 101 and the second annular groove 102. On the one hand, it prevents the coolant from seeping out from the edge of the annular groove, avoids the coolant leakage from corroding and damaging other parts inside the motor, and ensures the normal operating environment of the motor. On the other hand, it ensures that the coolant can flow according to the predetermined circulation path, maintains the stability and efficiency of the coolant circulation system, and thus improves the heat dissipation performance and overall reliability of the motor.

[0053] In this embodiment, in order to further improve the heat dissipation effect, the outer wall of the housing 1 is formed with a plurality of heat dissipation fins 108, wherein a thermal grease layer 107 is filled between the inner wall of the housing 1 and the outer wall of the main housing 601, and an efficient heat dissipation system is constructed through the synergistic effect of the heat dissipation fins 108 and the thermal grease layer 107. The heat on the main housing 601 is firstly quickly transferred to the housing 1 through the thermal grease layer 107, and then efficiently dissipated to the outside with the help of the heat dissipation fins 108 on the outer wall of the housing 1, thereby further improving the heat dissipation effect of the motor and ensuring the reliable operation of the motor in a stable temperature environment.

[0054] In this embodiment, rubber buffer pads are fixedly installed on the inner walls of the first annular groove 101 and the second annular groove 102. The rubber buffer pads can buffer the impact force generated by the flow of coolant and reduce damage to the inner walls of the annular grooves and the sealing structure.

[0055] In this embodiment, in order to facilitate the installation and fixation of the motor, a base 1001 is fixedly connected to the bottom of the shell 1, and a mounting hole 1002 is opened on the base 1001. In order to ensure the connection strength between the base 1001 and the shell 1, a plurality of reinforcing ribs 1003 are fixedly connected between the base 1001 and the outer wall of the shell 1.

[0056] In this embodiment, in order to prevent the first liquid collecting tank 103 and the second liquid collecting tank 104 from interfering with the installation when installing the motor, the bottom of the first liquid collecting tank 103 and the bottom of the second liquid collecting tank 104 are both 1 cm-5 cm higher than the bottom of the base 1001 .

[0057] Working principle: When in use, the external coolant flows into the first liquid collecting tank 103 through the liquid inlet pipe 1031, enters the liquid inlet 604 through the second annular groove 102, and then flows into the heat dissipation channel composed of the arc channel 6022 of the first assembly part and the second assembly part and the through hole 6002 of the main shell 601. After absorbing the heat generated by the operation of the motor, it flows out from the liquid outlet 605 to the first annular groove 101, then enters the second liquid collecting tank 104, and finally flows out of the motor through the liquid outlet pipe 1041 to complete the circulation heat dissipation.

[0058] The above description shows and describes several preferred embodiments of the present invention, but as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. Changes and variations made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
