Permanent magnet electric rollers have the advantages of small installation space, simple structure, high transmission efficiency, large starting torque, etc., which are conducive to energy saving and consumption reduction, and have obvious advantages in the application of belt conveyors. Permanent magnet electric roller manufacturers need to conduct multiple experimental tests on their products before the equipment leaves the factory. The diameter differences of permanent magnet electric rollers of various specifications and sizes have a great impact on the installation.
