if the supply frequency increases what happens to the motor load..

Answer / shinde

Assume motor having torque of 'X' Nm is of frequency 50Hz and voltage of 400V . if the frequency of the motor increased to 60Hz , in order to achieve same torque the V/F ratio should be same in either case. so motor may take more current in higher frequency to achieve same torque.
