Mining flameproof and intrinsically safe permanent magnet synchronous variable frequency speed regulation integrated electric drum

The permanent magnet synchronous variable frequency speed regulating integrated electric drum is a new type of drive device that integrates frequency converter, motor and electrical control. It directly drives the belt conveyor equipment to operate, replacing the traditional drive mode of asynchronous motor + hydraulic coupling + reducer + coupling + transmission drum.

The multi-phase permanent magnet synchronous electric roller uses advanced multi-phase permanent magnet motor technology to demonstrate excellent fault tolerance and high reliability.

Thanks to the redundant characteristics of the multi-phase motor, when one or two phases of the motor fail, a clever control strategy can be used to reduce power in the phase loss state without restarting or shutting down.
