[0002] An electric motor is a device that converts electrical energy into mechanical energy. It is also called a motor. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electrical rotational 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, which can be synchronous motors or asynchronous motors. The motor is mainly composed of a stator and a rotor. The direction of the force on the current-carrying conductor in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the motor is the effect of the magnetic field on the force on the current, causing the motor to rotate.

Through the heat dissipation box 501, sealing cover 502, guide spacer 503, heat dissipation plate 504, return hose 505, water inlet hose 506, heat insulating connecting sleeve 507 and docking male connector 508, when the device is installed on a continuously moving device such as a wheel or a device that cannot be externally connected, cold water circulation can be achieved through self-heat dissipation, thereby ensuring the heat dissipation effect of the stator coil 109.

[0034] During installation, the water inlet female connector 204 is connected to the water inlet hose 506 via the docking male connector 508, and the drainage female connector 205 is connected to the return hose 505 via the docking male connector 508; When in use, the power supply of the stator coil 109 is turned on, and the stator magnetic ring 308 is driven by the magnetic force to drive the first rotor side shell 301 and the second rotor side shell 303 to rotate. When the second rotor side shell 303 rotates, it drives the gear 409 to rotate through the inner gear ring 306. When the gear 409 rotates, it drives the drum 407 to rotate, so that the centrifugal blades 408 rotate. When the centrifugal blades 408 rotate, the centrifugal effect is generated to continuously drive the fluid in the middle toward the periphery, so that a negative pressure area is formed in the middle and a positive pressure area is formed on the periphery. The negative pressure area continuously draws in the external water flow, and the positive pressure area continuously pumps out the water flow. The water flow first enters the water inlet hose 506 from the heat dissipation box 501, and then enters the water inlet conduit 207 from the water inlet hose 506, and then enters the guide shell 402 to accelerate, and then along The guide pipe 406 discharges into the water inlet 104, and then enters the guide groove 102. The cold water entering the guide groove 102 flows around the guide groove 102, so that the water-cooled bracket 101 is cooled. The water-cooled bracket 101 introduces the heat of the stator coil 109 into the cold water, so that the temperature of the cold water increases. The heated water flows from the drain port 105 into the drain pipe 208 as it moves, and then into the return hose 505, and then flows back to the inside of the heat sink 501 along the return hose 505. Since the density of cold water is lower and the density of hot water is very high, the hot water dissipates heat in the upper part of the heat sink 501. As the heat decreases, the colder water reaches the bottom of the heat sink 501, and then enters the water inlet hose 506 for a new circulation, thereby ensuring that the stator coil 109 is cooled.
