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....
