Abstract

The invention provides a novel permanent magnet synchronous motor structure facilitating harmonic optimization, and belongs to the technical field of motor structures. The motor body comprises a stator, permanent magnets, and a permanent magnet bridge. The permanent magnets are located on the stator, and the permanent magnet bridge is disposed between the adjacent permanent magnets. The technicalmain points of the structure lie in that the permanent magnet bridge is disposed between the adjacent permanent magnets, thereby reducing the magnetic leakage between the magnetic poles, increasing the gas magnetic density, reducing the gap harmonic waves, improving the fundamental waves, improving the harmonic distortion rate, remarkably inhibiting the matrix pulse, reducing the harmonic waves ofthe motor, enabling the sinusoidal performances of the waveform to be better, and enabling the stability to be higher.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a novel permanent magnet synchronous motor structure which is beneficial to harmonic optimization. Background technique [0002] Permanent magnet synchronous motor refers to a synchronous motor that is excited by permanent magnets to generate a synchronous rotating magnetic field. Permanent magnet synchronous motors have high density, small size and high efficiency. With the development of magnetic materials and the progress of motor control technology, permanent magnet synchronous motors have become a research hotspot in the field of motors. However, the application of permanent magnet synchronous motors is limited due to too many internal harmonics. How to suppress harmonics is a key issue in the research of permanent magnet synchronous motors. Contents of the invention [0003] The purpose of the present invention is to provide a novel permanent magnet synchronous motor stru...
