Abstract

The invention discloses a hybrid cooling double-rotor single-stator disc type permanent magnet motor, and relates to the field of motors. The disc type permanent magnet motor is large in power density, materials with good thermal conductivity are widely adopted as a stator iron core at present, or devices such as a heat dissipation fan are additionally arranged, however, the overall weight of the motor is increased, and the motor is not suitable for the fields of lightweight electric automobiles and aerospace. The motor comprises a stator, a left rotor and a right rotor, the stator comprises an annular stator support frame and rib plates which are uniformly distributed in a surrounding manner, fan-shaped magnetic poles are arranged between adjacent rib plates, the stator support frame is provided with a circumferential cooling channel, each rib plate is provided with a radial cooling channel and communicates with the circumferential cooling channel, and continuous cooling pipelines are embedded in the cooling channels; and the peripheries of the left and right rotors are provided with annular cover plates used for sealing the motor, and the left and right rotors and the annular cover plates are provided with ventilation holes which are through internally and externally. Air cooling and liquid cooling mixed cooling is adopted, the motor is compact in overall structure, light in weight and good in cooling effect, and lightweight application is effectively achieved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a hybrid cooling dual-rotor single-stator disc permanent magnet motor. Background technique [0002] At present, traditional motors have disadvantages such as large size and low efficiency, and the selection of models in some fields is limited. The disc permanent magnet motor has the advantages of small size, light weight, high efficiency, and high torque density, and is suitable for fields such as electric vehicles and aerospace that have stricter requirements on motor performance. Disc permanent magnet motors are also known as axial flux motors, where the air gap magnetic field is distributed along the axial direction. In order to overcome problems such as unilateral magnetic pull, the middle stator double-sided rotor and the middle rotor double-sided stator are the most widely used axial disk permanent magnet motor structures. In the fields of electric vehicles and aviation, the motor,...
