Electrical Engineering · Single Phase Induction Motors
As per the cross-field theory, if the rotor of a single-phase induction motor is given an initial push and starts rotating, what enables the motor to continue running on its own?

Share:
- 1The inertia of the rotor is enough to sustain the motion.
- 2The pulsating stator flux automatically converts into a rotating magnetic field.
- 3The starting winding is kept in the circuit permanently.
- 4The rotation causes the rotor conductors to cut the main stator flux, inducing a cross-field that produces a continuous torque.✓
Correct answer
The rotation causes the rotor conductors to cut the main stator flux, inducing a cross-field that produces a continuous torque.
