Name three factors that determine the torque produced by an induction motor.
The reason why the starting torque of a series motor is higher than a shunt motor is
because the series motor has
O more current flowing through its armature
O a stronger net magnetic field around both coils during the inrush of stator current
Name three factors that determine the amount of voltage induced in the rotor of a wound-rotor motor.
