Product Description

Product Overview

Qi’an 1000kW Six-Phase Four-Quadrant Special Variable Frequency Drive. A six-phase motor has a single winding current that is only half that of a three-phase motor. The six-phase configuration significantly reduces low-order harmonics, greatly minimizing motor vibration and noise, and lowering rotor losses. The motor voltage is reduced, enhancing electrical safety. The drive can operate even with a missing phase, thereby improving system reliability. Depending on power requirements, the drive can be configured to operate in either three-phase or multi-phase mode.

Rated power: 1000kW
Input voltage range ：690V_AC
Rated output current: 25A

Product Features

A six-phase motor has a single winding current that is only half that of a three-phase motor. The six-phase configuration significantly attenuates lower-order harmonics, greatly reducing motor vibration and noise, as well as lowering rotor losses.
It can operate with missing phases, enhancing system reliability. Depending on power requirements, it can adopt three-phase or multiphase operation control modes to support six-phase synchronization as well as six-phase phase-shift control.
Operating frequency up to 600 Hz
Supports multiple communication protocols (CAN, RS485, ModBus)
