Title:
COOLING WATER CHANNEL OF EXTERNAL ROTOR MOTOR AND MANUFACTURING METHOD THEREFOR, EXTERNAL ROTOR MOTOR AND COOLING SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/088376
Kind Code:
A1
Abstract:
A cooling water channel of an external rotor motor, wherein an external rotor motor acted on thereby comprises a stator core, a motor end cover, and an inner casing; the inner casing tightly fits with and is mounted on an inner side of the stator core of the external rotor motor, and the water channel is provided in the inner casing; the water channel is folded back and distributed layer by layer in the axial direction of the external rotor motor, and two ends of the water channel are provided with an axial water intake segment and a water discharge segment; ports of the water intake segment and the water discharge segment are a water inlet and a water outlet, respectively; the water inlet and the water outlet are disposed on the same end of the external rotor motor; the motor end cover of the end at which the water inlet and water outlet are located is provided with a water intake nozzle and a water discharge nozzle that are connected to the water inlet and the water outlet, respectively. The present invention further relates to a method for manufacturing a cooling water channel of an external rotor motor, and an external rotor motor and a cooling system thereof. The present invention relates to the technical field of motor heat control. During the operation of the external rotor motor having the cooling water channel or cooling system, the increase in temperature is small, temperature equalization is good, and temperature control consumes little energy.
