AI Technical Summary

Problems solved by technology

Therefore, most permanent magnet synchronous motor windings will generate large high-order harmonics due to magnetic circuit saturation and affect motor performance
The permanent magnet Halbach (Halbach) array arrangement of the new motor not only needs to consider the size of the permanent magnet block, the manufacturability of magnetization and installation, but also the processing and assembly of the permanent magnet is difficult

Abstract

The invention discloses a novel stator winding structure based on an axial coreless motor, and the structure comprises at least three single coils with the same specification, the at least three single coils are annularly distributed to form a winding, and each single coil of the winding is arranged in an annular non-uniform manner. The novel stator winding structure based on the axial coreless motor can effectively reduce the higher harmonics of counter electromotive force of the motor and can improve the sinusoidal property of counter electromotive force waveforms. The stator winding is simple in process, convenient to assemble and low in cost, the working efficiency of the motor is improved, the cost performance and the flexibility of processing and manufacturing are also improved, andthe mechanical strength and the heat dissipation characteristic are better.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a novel stator winding structure based on an axial coreless motor. Background technique [0002] Ironless motor is a new type of special motor representing the future development direction of the motor industry. It is divided into ironless motor and ironless generator. It adopts ironless coil, carbon brush, nonmagnetic damping and rare earth permanent magnet electric technology, which changes the traditional The motor uses a silicon steel sheet and wound stator structure, combined with electronic intelligent frequency conversion technology, so that the efficiency of the motor system can be increased to more than 95%; the traditional permanent magnet synchronous motor, in order to improve the utilization of the winding in the effective space, the winding is always designed to be evenly distributed . Therefore, most of the permanent magnet synchronous motor windings will generate l...
