What value of resistance/ph have so that the starting torque is half the max torque.
A 3 φ I.M. has synchronous speed of 250rpm and 4% slip at full load. The rotor has a resistance of 0.02Ω/ph and stand still reactance of 0.15Ω/ph. Calculate i) The speed at which max torque is developed. ii) The ratio of maximum to F. L. torque. iii) The ratio of maximum to starting torque.
Calculate speed of motor when delivery maximum voltage. Also calculate the resistance to be added to achieve 3/4th of maximum torque at time of starting.
How can the starting current of an induction motor be reduced? Answer : The starting current of an induction motor can be quite high, often several times the full-load current, which can cause issues like voltage drops in the supply line and damage to the motor windings ... -duty vs. light-duty), motor type, cost, and the need for controlling the acceleration profile....
