Question 38Electricity & Electronics - Assistant Engineer

The correct answer is B) Motor rotation can be reversed by reversing the leads on the starting winding. In a split-phase induction motor, the starting winding and the main winding are connected in parallel. By reversing the leads on the starting winding, the direction of the rotating magnetic field produced by the starting winding is reversed, which in turn reverses the direction of rotation of the motor. The other options are incorrect because: A) Motor speed cannot be readily adjusted from zero to full speed in a split-phase induction motor, as it typically operates at a fixed speed. C) Reversing the motor rotation requires changing the wiring or leads, as described in the correct answer. D) A split-phase induction motor cannot be operated as a generator without significant modifications to the wiring and circuitry.
