Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a six-phase coil and a motor. Background Art

[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 and acts on the rotor to form a magneto-electrical rotating torque. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the motors in the power system are AC motors. A three-phase motor refers to an AC motor driven by three-phase alternating current. A three-phase motor means that when the phases of the three-phase stator winding of the motor differ by 120 electrical degrees, a rotating magnetic field will be generated when three-phase alternating current is passed through. This rotating magnetic field cuts the rotor winding to generate electricity.

The torque pulsation is relatively large and the torque density is relatively low, which makes the stability of the wheel hub relatively poor during rotation and cannot make the output of the motor in each frequency band meet the requirements of actual applications.

[0033] During use, the controller is first activated to convert the coil rear tap 109 into a star connection, and then the relay contacts are closed to supply power to the coil front tap 106, so that the six-phase winding coil 105 is energized. After the six-phase winding coil 105 is energized, a circular magnetic field is formed. The magnetic force of the circular magnetic field pushes the magnet ring group 303 to drive the rotor housing 301 and the annular housing 302 to rotate. After the rotation reaches a certain speed, the controller is activated to convert the coil rear tap 109 into a delta connection, so that the motor rotates at a high speed and high torque. When absorbing oil, first, 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.

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 penetrates through the oil-seeping sponge ring 502 to the bearings on the surface of the supporting external block 204 and the supporting isolation block 205 for lubrication.

The hot water pipe 709 is fixedly connected to the surface of the coil heat exchange ring 708, and one end of the hot water pipe 709 passes through one side of the support isolation block 205 and extends to the other side of the support isolation block 205. The water pipe 710 is fixedly connected between the output end of the first heat dissipation electromagnetic switch valve 705 and the coil heat exchange ring 708. 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 support external block 204 and extends to the other side of the support external block 204, so that the six-phase winding coil 105 can be cooled by water cooling during use to prevent the six-phase winding coil 105 from overheating easily.

[0036] When 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. When dissipating heat, start the liquid pump 704, open the first heat dissipation electromagnetic switch valve 705 and the second heat dissipation electromagnetic switch valve 706, and the liquid pump 704 drives the water to flow in one direction. The cold water inside the external condenser first enters the intermediate conversion chamber 701 from the cold water pipe 711, and then enters the liquid pump 704. After the cold water enters the intermediate conversion chamber 701, the heat inside the device is introduced into the cold water through the heat conduction of the intermediate conversion chamber 701, the packaging plate 702, the heat conduction plate 703 and the air, so that the device The internal temperature is lowered, and then the cold water is discharged from the liquid pump 704, and then enters the first heat dissipation electromagnetic switch valve 705 along 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 goes around from the bottom of the coil heat exchange ring 708 to the top of 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, and the water flow is heated. After the water flow is heated, it is discharged along the hot water pipe 709, thereby entering the external condenser and cooling it inside. The cooled water flow becomes cold water again, and then the cold water continues to circulate through the cold water pipe 711 to dissipate heat.
