Motor with cooling device

摘要

A motor includes a main body and a cooling device. The cooling device includes a mounting seat defining an inlet hole and an outlet hole spaced from the inlet hole, and a cooling pipe communicating with the inlet hole and defining a plurality of ejection holes on a sidewall. The main body includes a rotor sleeved and sealed on the mounting seat. The cooling pipe is received in the rotor. Cooling liquid sprays at the rotor via the inlet hole and the ejection holes, and then the cooling liquid flow out of the rotor via the outlet hole.

1. A motor comprising:
a fixed seat, the fixed seat comprising:
a bottom plate,a base seat parallel to, and spaced from, the bottom plate, andfour support shafts interconnecting the bottom plate and the base seat; a cooling device comprising:
a mounting seat installed on the base seat of the fixed seat and defining an inlet hole and an outlet hole spaced from the inlet hole, anda cooling pipe communicating with the inlet hole and defining a plurality of ejection holes on a sidewall thereof, one end of the cooling pipe being inserted into the inlet hole of the mounting seat; a main body comprising:
a rotor sleeved and sealed on the mounting seat and configured to receive the cooling pipe,a stator sleeved on the rotor, anda housing sleeved on the stator and supported by the base seat of the fixed seat; and a rotating shaft coupled to the rotor, wherein the inlet hole is configured to enable cooling liquid to flow into the cooling pipe, the outlet is configured to enable the cooling liquid, being sprayed at the rotor via the ejection holes, to flow out of the rotor.
