A single-phase induction motor is__________?
Correct answer: C. inherently non-self-starting with low torque
- A. inherently self-starting with high torque
- B. inherently self-starting with low torque
- C. inherently non-self-starting with low torque
- D. inherently non-self-starting with high torque
Explanation
A single-phase induction motor produces a pulsating magnetic field whose forward and backward torque components cancel at standstill. It therefore has no starting torque by itself and requires an auxiliary starting method.
