Distributed formed winding disc-type motor

Abstract

The invention discloses a distributed formed winding disc-type motor. The motor comprises a planetary gear train, a front end cover, a stator, a rotor, a rear end cover and a shell; the front end cover and the rear end cover are respectively assembled on the left side and the right side of the shell, and the stator is composed of a left stator body and a right stator body; stator grooves are formed in the left stator body and the right stator body respectively, and formed windings are embedded in the stator grooves and arranged in a distributed winding mode; the rotor comprises a rotor bracket, magnetic steel, a rotating shaft and a bearing I; the planetary gear train comprises a sun gear, a planet gear, a gear ring, a planet carrier, a cover plate and a bearing II. According to the invention, the formed windings are embedded in the stator grooves in a distributed arrangement manner; the height of the end parts of the upper and lower formed winding of each groove is reduced through themutual embedding of U-shaped structures, the cogging torque is reduced through the distributed formed windings, the performance of the motor is improved, and the reliability of the motor is improvedby virtue of good structural strength and excellent insulating property of the formed windings.

Description

technical field [0001] The invention relates to the technical field of disc motors, in particular to a disc motor with distributed forming windings. Background technique [0002] The disc motor is also called the disc motor. The rotor and stator of the motor are dressed inside and outside. The disc motor is thin, the stator is on the flat substrate, and the rotor is covered on the stator. Generally, the stator is a coil and the rotor is a permanent magnet. Or a disk with permanent magnets glued on it. [0003] Restricted by the structure of the disc motor, the traditional disc motor mostly adopts a centralized winding design with a chute to reduce the cogging torque, but the chute makes the motor core production and wire embedding process much more complicated; and The scattered windings arranged in a distributed manner are another big problem for the insulation and end fixing of the windings. [0004] Therefore, in view of the above problems, it is urgent to develop a dis...
