Question 387Electricity & Electronics - QMED
70% to passOf the following listed single-phase induction motors, which has the highest starting torque?
Ashaded pole motor
Bcapacitor start induction run motor
Cpermanent split capacitor motor
Dresistive start induction run motor
AI Explanation
The correct answer is B) capacitor start induction run motor. The capacitor start induction run motor has the highest starting torque among the single-phase induction motors listed. This is because the capacitor in the starting winding creates a phase shift that increases the starting torque, allowing the motor to overcome higher initial loads. The other motor types, such as the shaded pole, permanent split capacitor, and resistive start induction run motors, do not have the same level of starting torque enhancement provided by the capacitor circuit.
