Thank's for the reply. I assume that raising the voltage / Hz will reduce the current at a given frequency.
Any thoughts on what values would be needed to limit the torque to about 86% at 60Hz? Should the curve still be linear? Should I maintain a certain V / Hz value along the entire curve? If I have a drive supply say 300 V at 15 Hz, or 400 V at 15 Hz, will it cause any damage?
