can we run all LT motors at 360 volts which are normally rated 415+/-10% voltage rating..

Answer / bala_vlsi

No, because we can achieve the recommended motor torque
at 415 V+/- 10 % level only (torque is directly
proportional to the current (P = I²/R) If the torque is in
low condition, required more current for try to achieve
the specified torque so automatically the motor will
generate more heat and motor will be damage / burn .

Answer / j.karthik

The above answer is correct. While we can run the motor
using the 360Volt then the motor will rotate only the lesser
amount of speed than the rated 3000/1500 rpm. and it cannot
give sufficient output...and also produces a heat in the
motor winding.......
