The invention discloses a stator core slot structure of an aviation permanent magnet motor. The stator core slot structure comprises a permanent magnet motor base, a stator core slot, a stator winding, a rotor and a base, wherein a rotating shaft is arranged in the permanent magnet motor base; the end part of the rotating shaft is connected with a cooling fan; a rotor is arranged outside the rotating shaft; the stator core slot is formed in the outer part of the rotor; and the stator winding is arranged outside the stator core slot. The stator winding is welded on the permanent magnet motor base, a condenser pipe is distributed outside the stator winding, a control device is arranged at the end part of the condenser pipe, the condenser pipe is connected with a compressor, the compressor isconnected with an evaporator, a base is welded and distributed at the bottom of the permanent magnet motor base, and spring connecting ribs are welded between the base and the permanent magnet motorbase. According to the stator core slot structure, mechanical production is realized, the stability of the permanent magnet motor base is improved, the noise in work is reduced, the permanent magnet motor base is effectively cooled, the internal temperature is dissipated, and the service life is prolonged.
Description
technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to a stator core slot structure of an aviation permanent magnet motor. Background technique [0002] The permanent magnet synchronous motor cannot be started directly through three-phase AC, because the rotor inertia is large, the magnetic field rotates too fast, and the stationary rotor cannot start to rotate with the magnetic field at all. The power supply of the permanent magnet synchronous motor is provided by a frequency converter. When starting, the output frequency of the frequency converter rises continuously from 0 to the working frequency, and the motor speed rises synchronously with the output frequency of the frequency converter. Changing the output frequency of the frequency converter can change the motor speed. It is a very good variable frequency speed regulating motor. [0003] The existing stator core slot structure of aviation permanent magnet moto...
