Permanent Magnet Magnet Synchronous Motor Manufacturers

Permanent magnet electric roller has changed the complex transmission chain of traditional belt conveyor, which is composed of motor + coupler + reducer + coupler + transmission roller. It integrates drive, transmission and roller, and brings a revolutionary change of belt conveyor drive system.

The permanent magnet electric drum fully considers the requirements of driven equipment, frequency converter and control system in the speed regulation process. It has the advantages of low speed, high torque, wide speed regulation range, anti frequency converter DV / dt high-frequency pulse harmonic, high efficiency and energy saving, low noise, long service life and high reliability. It is an ideal driving product for bulk material transportation machinery.
