A three-phase induction motor is supplied from a 400 V, 3 phase, 50 Hz supply. If the supply voltage is reduced by 40 V, what will happen to the torque as compared to the torque developed at 400 V?
1
The torque will be increased by 19 percent
2
The torque will be reduced by 19 percent
3
The torque will be increased by 10 percent
4
The torque will be reduced by 10 percent
