Description

There is no excitation loss on the rotor of permanent magnet synchronous motor, and there is no friction loss and contact loss between the brush and the slip ring. Therefore, the permanent magnet synchronous motor has high efficiency and its power factor can be designed near 1. AC permanent magnet synchronous motor has the advantages of small volume, light weight, high efficiency and energy saving, good control performance, easy to make low-speed direct drive device, main drive shaft, gear reducer and so on, and the comprehensive energy saving index is 10-40%. After independent innovation, our company has developed a series of high efficiency and energy saving permanent magnet synchronous motor (PMSM) for various industries.
