3 phase AC frequency conversion asynchronous motor

This 3 phase AC frequency conversion asynchronous motor for electric automobiles, works with its controller. Compared with DC system, it’s specially strong on:

Brushless, free of maintenance, higher efficiency, higher power density, wider speed adapting, bigger torque, electromagnetic braking, repower-supply, more capable of over-loading, and possible to get infinite variable speed. It is getting instead of DC motor system depending on these strong points.

System features:

² DSP wholly digital control

² IGBT power module

² Space vector control

² Infinite variable speed

² Power feedback and re-braking

² Automatically distinguish of motor parameters

² Processing by hand-holding units

² RS485/ CAN bus communication

² Self-adapting rotor control

Protection functions:

² Over/low voltage protection for battery

² Dual-overcurrent protection

² Over-heat power attenuation protection for controller

² Over-heat power attenuation protection for controller

² High speed limiting protection

² High speed limiting of over-powered
