The Global Pioneer--Five-Phase Permanent Magnet Synchronous Electric Drum Appeared in Taiyuan Coal Fair

The outstanding advantage of polyphase motor is high reliability operation, which is widely used in other industries requiring high reliability. Excellent introduced polyphase motor technology to permanent magnet electric drum for the first time.

The power supply of the five-phase permanent magnet electric drum drive system is the conventional three-phase power supply, and the inverter is configured with three-phase input power and five-phase AC output, so the user only needs to provide three-phase power supply.

Benefit from the redundant characteristics of the number of phases of the polyphase motor, when one or several phases of the polyphase motor fail, as long as it is not less than three phases, the control strategy can be changed to make the motor run at reduced power in the case of phase break, without restarting or stopping.
