Speed/frequency/current/voltage effect while motor running on VFD
WHAT IS THE RATIO OF SPEED, FREQUENCY, CURRENT AND VOLTAGE EFFECT WHILE MOTOR RUNNING ON VFD?

Amardip,
The seed of the AC motor is based on the frequency "rotating flux"
When you vary the speed without changing the voltage you will change the torque curve of the motor. keeping a V/F ration constant the torque curve of the motor will remain the same.
