Abstract

The invention provides a permanent magnet motor with a heat dissipation function. The motor comprises a stator component, a rotor component and two sealing end covers which cover the two ends of the stator component and the rotor component to form a sealed space. The stator component comprises a stator iron core, a stator coil and a coil installation groove. The coil installation groove is arranged on the stator iron core, the stator coil is arranged in the coil installation groove, the stator component is provided with a conveying channel for inputting a cooling medium into the stator coil and a discharging channel for discharging heat of the stator coil, and the conveying channel, the coil installation groove, the sealed space and the discharging channel communicate in sequence. The permanent magnet motor has the advantages of the good heat dissipation effect, the compact layout and the like.

Description

technical field [0001] The invention relates to the field of motor equipment, in particular to a permanent magnet motor with heat dissipation function. Background technique [0002] At present, permanent magnet motors usually use cooling medium to dissipate heat, and a cooling circuit is set on the motor casing. The heat generated by the stator coil due to copper loss and the stator core due to iron loss is conducted to the casing through the stator core, and then cooled by the cooling circuit in the casing. The medium removes heat. The heat generated by the stator coil of the existing permanent magnet motor cannot be taken away in time, so that the heat accumulation of the stator coil increases, causing problems such as burning of the motor coil, especially at the end of the stator coil, the temperature rises faster and the heat dissipation capacity Can not meet the requirements. Contents of the invention [0003] The technical problem to be solved by the present invent...
