Permanent magnet motors
Flameproof permanent magnet synchronous electric roller for Coal Mining
Compared with the traditional driving system, it directly drives the load, with compact structure and convenient installation, which greatly saves the installation space; The efficiency reaches IE4 and above, and the comprehensive energy saving rate reaches over 30%; Starting with low frequency and large torque, the starting torque can reach 2.5 times, which solves the problem of starting under heavy load.
