Abstract

The invention discloses a 153-slot and 138-level high efficiency permanent magnet synchronous motor for a mining overhead man-riding device, which mainly relates to the technical field of synchronousmotors. The motor comprises a casing, a rotor and a stator, wherein the rotor of the casing is internally provided with permanent magnets, the stator is located at the center of the casing, and the stator is wound with coils corresponding to the permanent magnets; and the internal part of the casing adopts a 158-slot and 138-level slot-pole cooperation mode. The rotor is connected with a driving wheel through a connector, and the driving wheel is provided with a rope slot used for placing a steel wire rope. The coils perform three-phase winding according to the 158-slot and 138-level slot-polecooperation mode. The invention has the beneficial effects that the working efficiency of the mining overhead man-riding device is improved, the weight of the headpiece is reduced, the failure rate of the headpiece portion of the mining overhead man-riding device is reduced, and the service life of the steel wire rope is prolonged.

Description

technical field [0001] The invention relates to the technical field of synchronous motors, in particular to a 153-slot 138-stage high-efficiency permanent magnet synchronous motor for a mine monkey car. Background technique [0002] The head drive device of the mining monkey car is combined with the existing equipment in the industry, and all parts adopt the method of asynchronous motor accelerator and decelerator plus driving wheel. The normal operation of the mining monkey car is generally divided into three states, low-speed operation state, medium-speed operation state, and high-speed operation state. The existing method of adding the driving wheel by the accelerator and decelerator of the asynchronous motor cannot guarantee the operating efficiency of the motor, and the average efficiency of the motor is about 60%. Moreover, the way of the asynchronous motor acceleration and decelerator plus the driving wheel will increase the weight of the machine head, increase the p...
