Title
(EN) Motor with spiral cooling type rotor, and compressor
(ZH) 具有螺旋冷却式转子的电机以及压缩机
Abstract
(EN)
The invention provides a motor with a spiral cooling type rotor, and a compressor, and discloses a motor and a compressor with the same. The motor comprises a cylinder with a containing cavity, a stator and a rotor, wherein the stator and the rotor are arranged in the containing cavity, the stator is arranged on the outer side of the rotor in a sleeving mode, an air gap channel is formed between the inner circumferential wall of the stator and the outer circumferential wall of the rotor, and a fluid channel used for allowing a cooling medium to flow through is arranged in the air gap channel in a bending mode. According to the invention, the cooling medium can be in full contact with the outer circumferential wall of the rotor and the inner circumferential wall of the stator when passing through the bent cooling medium channel so as to fully cool the motor, so that the cooling effect of the motor is improved.
