Description
Technical Field
[0001] This invention relates to the field of motor technology, specifically to a six-phase coil and a motor. Background Technology
[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field, which acts on the rotor to create magnetoelectric torque. Electric motors are classified into DC motors and AC motors according to the power source they use. Most electric motors in the power system are AC motors. A three-phase motor is an AC motor driven by three-phase alternating current. A three-phase motor is one in which the three phases of the stator windings are 120 electrical degrees out of phase. When three-phase alternating current is applied, a rotating magnetic field is generated. This rotating magnetic field cuts the rotor windings to generate electricity.

They typically use three-phase coils for internal winding, resulting in relatively large torque ripple and relatively low torque density.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0042] Please see Figure 1-18 The six-phase coil includes a coil winding mechanism, which includes a silicon steel sheet 101, an insulating bushing 102, teeth 103, a winding groove 104, and a six-phase winding coil 105. The insulating bushing 102 is fixedly connected to the inner wall of the silicon steel sheet 101. The teeth 103 are integrally disposed on the surface of the silicon steel sheet 101. The winding groove 104 is disposed between two adjacent teeth 103. The six-phase winding coil 105 is wound inside the winding groove 104.
[0043] In this configuration, each phase six-phase winding coil 105 is formed by continuously winding with toothed 103 wire. The silicon steel sheet 101 is evenly distributed around its circumference with any number of teethed 103, which can be 36, 45, 48, 54, or 63. Correspondingly, the number of slots 4 formed between the evenly distributed teethed 103 on the silicon steel sheet 101 are 36, 45, 48, 54, or 63 slots, respectively. The winding on each phase coil consists of a single... The coil can be wound with single wires or multiple wires. When wound with single wires, the number of single wires in each phase coil is 1, 2, 3, 4, 5 or 6, and the winding is connected in a 1-parallel, 2-parallel, 3-parallel, 4-parallel, 5-parallel or 6-parallel manner. When wound with multiple wires, the number of multiple wires in each phase coil is 1 group, 2 groups, 3 groups, 4 groups, 5 groups or 6 groups, and the winding is connected in a 1-parallel, 2-parallel, 3-parallel, 4-parallel, 5-parallel or 6-parallel manner.
[0044] The coil winding mechanism includes a front coil tap 106, a ring-shaped junction box 107, an external bus 108, and a rear coil tap 109. The front coil tap 106 is integrally located at the front end of the six-phase winding coil 105. The ring-shaped junction box 107 is fixedly installed at one end of the front coil tap 106. The external bus 108 is fixedly installed on the surface of the ring-shaped junction box 107. The rear coil tap 109 is integrally located at the rear end of the six-phase winding coil 105. The rear coil tap 109 is externally connected to a controller via the external bus 108. The controller is built-in for controlling the six-phase winding coil. The star-delta switching module dynamically configures the phase winding coils 105 into star or delta connections. Through the set coil winding mechanism, stator support mechanism, rotor hub mechanism, lubrication pump mechanism, and lubrication seepage mechanism, it can reduce torque pulsation, increase torque density, and reduce single-phase current pressure, thereby improving the stability of hub rotation. At the same time, it can also dynamically switch the star-delta connection mode of the six-phase winding coils 105 to ensure that the motor switches between light load start-up and high torque and high speed, thereby ensuring that the output of the motor in each frequency range meets the requirements of actual application.
[0045] The motor includes a coil winding mechanism, a stator support mechanism inside the coil winding mechanism, a rotor hub mechanism on the surface of the stator support mechanism, a lubrication pump mechanism inside the stator support mechanism, and lubrication seepage mechanisms on both ends of the stator support mechanism, so as to facilitate the combination of the electrode structure and the hub structure, and facilitate the operation of the electric vehicle.
[0046] The stator support mechanism includes a main support frame 201, a main support shaft 202, hexagonal shaft heads 203, an external support block 204, and a support isolation block 205. There are two main support frames 201, which are distributed opposite to each other and are fixedly connected inside an insulating bushing 102. This allows the insulating bushing 102 to insulate the two main support frames 201 from the silicon steel sheet 101, preventing easy leakage. The main support shaft 202 is fixedly inserted between the two main support frames 201. The hexagonal shaft heads 203 are integrally mounted at both ends of the main support shaft 202. The external support block 204 and the support isolation block 205 are both fixed... The external bus 108 is sleeved on the surface of the support spindle 202. One end of the external bus 108 passes through the support external block 204 near the support main frame 201 and extends out to the other side of the support external block 204. The support external block 204 and the support isolation block 205 are located on the outside of the two support main frames 201 respectively. Through the support main frame 201, support spindle 202, hexagonal shaft head 203, support external block 204 and support isolation block 205, the two support main frames 201 can form a support for the silicon steel sheet 101 during use, and facilitate the protection of the internal lubrication pump mechanism. The two support main frames 201 are connected to ensure that the lubrication pump mechanism can be installed smoothly.
[0047] The rotor hub mechanism includes a rotor housing 301, an annular housing 302, a magnet ring assembly 303, a mounting groove 304, and a heat dissipation groove 305. There are two rotor housings 301, which are distributed opposite each other and rotatably connected to the surfaces of the supporting outer block 204 and the supporting isolation block 205 via bearings. The annular housing 302 is fixedly connected between the two rotor housings 301. The magnet ring assembly 303 is fixedly installed inside the annular housing 302. The mounting groove 304 is located on the outer surface of the annular housing 302, and the heat dissipation groove 305 is embedded in the surface of the rotor housing 301. The rotor housing 301, annular housing 302, magnet ring assembly 303, mounting groove 304, and heat dissipation groove 305 together ensure the assembly, disassembly, fixation, and protection of the magnet ring assembly 303. The annular housing 302 facilitates the installation of external tires.
[0048] In this first embodiment, the lubrication pump oil mechanism includes an oil reservoir ring 401, a mounting plate 402, an elastic membrane 403, an outer support shell 404, a constant pressure hole 405, and a sponge filling block 406. The oil reservoir ring 401 is fixedly sleeved between two supporting main frames 201, and an oil storage groove is formed on the surface of the oil reservoir ring 401. The mounting plate 402 is fixedly connected to the inner wall of the oil storage groove, the elastic membrane 403 is fixedly connected between the oil storage groove and the mounting plate 402, and the outer support shell 404 is fixedly connected to the inner wall of the oil reservoir ring 401. A constant pressure hole 405 is formed through the outer support shell 404. A sponge filling block 406 is installed between the oil storage tank and the elastic membrane 403. The constant pressure hole 405 ensures that a large negative pressure is not formed between the elastic membrane 403 and the outer support shell 404 when the elastic membrane 403 contracts and expands, and at the same time ensures the protective effect. The sponge filling block 406 can improve the elasticity and also ensure that the lubricating oil is evenly penetrated and filled into the oil storage tank through capillary action, reducing the shaking of the lubricating oil.
[0049] The lubrication pump mechanism includes an oil pump 407, an electromagnetic distribution valve 408, a lubrication electromagnetic switch valve 409, an oil drain pipe 410, and an oil inlet pipe 411. The oil pump 407 is fixedly mounted on the surface of the mounting plate 402 and is located above the supporting spindle 202. The electromagnetic distribution valve 408 and the lubrication electromagnetic switch valve 409 are respectively fixedly mounted on both sides of the oil reservoir ring 401. The oil drain pipe 410 is fixedly connected between the output ends of the electromagnetic distribution valve 408, the lubrication electromagnetic switch valve 409, and the oil pump 407. The oil inlet pipe 411 is fixedly connected to... At the oil inlet end of the electromagnetic distribution valve 408, and with one end of the oil inlet pipe 411 passing through the support outer block 204 near the support main frame 201 and extending out to the other side of the support outer block 204, through the provided oil storage ring 401, mounting plate 402, elastic membrane 403, outer support shell 404, constant pressure hole 405, sponge filling block 406, oil pump 407, electromagnetic distribution valve 408, lubrication electromagnetic switch valve 409, oil drain and connection pipe 410 and oil inlet pipe 411, lubricating oil can be pumped and temporarily stored during motor operation, ensuring smooth distribution of lubricating oil.
[0050] The lubrication and oil seepage mechanism includes an oil sealing shell 501, an oil seepage sponge ring 502, a sliding seal ring 503, and an oil guide pipe 504. There are two oil sealing shells 501, which are respectively fixedly sleeved on the surface of the supporting outer block 204 and the supporting isolation block 205. The oil seepage sponge ring 502 is fixedly connected to the surface of the oil sealing shell 501, and its surface is slidably connected to the inner surface of the rotor housing 301. The sliding seal ring 503 is fixedly connected to one side of the oil sealing shell 501, and its surface... The oil guide pipe 504 is slidably connected to the inner surface of the rotor housing 301 and is fixedly connected between the electromagnetic distribution valve 408 and one of the oil sealing shells 501 and between the lubrication electromagnetic switch valve 409 and the other oil sealing shell 501. Through the oil sealing shell 501, the oil seepage sponge ring 502, the sliding seal ring 503 and the oil guide pipe 504, the pumped lubricating oil can be evenly leaked to the bearings on the surface of the supporting outer block 204 and the supporting isolation block 205 through the oil seepage sponge ring 502 during use, ensuring smoother rotation of the rotor hub mechanism.
[0051] In use, the controller is first started to convert the coil back tap 109 into a star connection. Then, the relay contact is closed to energize the coil front tap 106, which energizes the six-phase winding coil 105. After the six-phase winding coil 105 is energized, a ring magnetic field is formed. The magnet ring group 303 receives the magnetic force of the ring magnetic field and drives the rotor housing 301 and the ring housing 302 to rotate. After rotating to a certain speed, the controller is started to convert the coil back tap 109 into a delta connection, so that the motor can rotate at high speed and high torque.
[0052] When drawing oil, firstly, the two oil guide pipes 504 are opened through the electromagnetic distribution valve 408 and the lubrication electromagnetic switch valve 409, and the oil inlet pipe 411 is closed through the electromagnetic distribution valve 408. Then, oil is guided to the input end of the oil inlet pipe 411. The oil pump 407 is started, and the oil pump 407 draws out the air inside the oil storage ring 401, causing the elastic membrane 403 and the sponge filling block 406 to contract. Then, the two oil guide pipes 504 are closed through the electromagnetic distribution valve 408 and the lubrication electromagnetic switch valve 409, and the oil inlet pipe 411 is opened through the electromagnetic distribution valve 408. At this time, the elastic membrane 403 and the sponge filling block 406 return to their original position due to their own elastic expansion, thereby drawing the lubricating oil from the outer wall into the oil storage ring 401 through the oil inlet pipe 411 for storage. Then, the oil inlet pipe 411 is closed through the electromagnetic distribution valve 408.
[0053] When pumping oil, the two oil guide pipes 504 are opened through the electromagnetic distribution valve 408 and the lubrication electromagnetic switch valve 409, and the oil pump 407 is started. The oil pump 407 draws out the lubricating oil inside the oil storage ring 401, so that the lubricating oil enters the interior of the two oil sealing shells 501 along the two oil guide pipes 504, and then permeates through the oil seepage sponge ring 502 to the bearings on the surface of the support outer block 204 and the support isolation block 205 for lubrication. After the oil pump 407 pumps out the lubricating oil, the elastic membrane 403 and the sponge filling block 406 also contract synchronously.

Between the input and output ends, the coil heat exchange ring 708 is fixedly connected to the surface of the silicon steel sheet 101, and the surface of the coil heat exchange ring 708 is in contact with the surface of the six-phase winding coil 105.

The cold water pipe 711 is fixedly connected to the input end of the second heat dissipation electromagnetic switch valve 706, and one end of the cold water pipe 711 passes through one side of the supporting external block 204 and extends to the other side of the supporting external block 204, so that the six-phase winding coil 105 can be cooled by water cooling during use, and the six-phase winding coil 105 can be prevented from overheating easily.
[0056] In use, first connect the cold water pipe 711 to the output end of the external condenser, and connect the hot water pipe 709 to the input end of the external condenser. During heat dissipation, start the liquid pump 704, and open the first heat dissipation solenoid valve 705 and the second heat dissipation solenoid valve 706. The liquid pump 704 drives the water flow in one direction. The cold water inside the external condenser first enters the intermediate conversion chamber 701 through the cold water pipe 711, and then enters the liquid pump 704. After the cold water enters the intermediate conversion chamber 701, the heat is transferred from the device to the cold water through the intermediate conversion chamber 701, the encapsulation plate 702, the heat conduction plate 703, and the air. The internal temperature is reduced, and then cold water is discharged from the liquid pump 704. It then enters the first heat dissipation electromagnetic switch valve 705 through the connecting pipe 707, and then enters the coil heat exchange ring 708 through the water guide pipe 710. At this time, the cold water flows from below the coil heat exchange ring 708 to above the coil heat exchange ring 708. Through the heat conduction of the coil heat exchange ring 708, the heat generated by the six-phase winding coil 105 is introduced into the cold water, which heats the water flow. After the water flow is heated, it is discharged along the hot water pipe 709, and then enters the external condenser and is cooled inside it. The cooled water flow becomes cold water again, and then the cold water continues to circulate and dissipate heat through the cold water pipe 711.
