Unique Mobility 50hp BLDC First Test @ 50V

Описание: A friend had bought an old electric car just for this propulsion system. It is a mid 90s 200V 200A brushless DC drive system from Unique Mobility ( now UQM Technologies). I had no data or instructions for the controller so I had to trace out the logic control board.
This first run is only at 52VDC just to verify everything works correctly. The power is supplied from a small 120V variac feeding a bridge rectifier and smoothing cap.
