Explanation:
Single-phase capacitor run induction motors are widely used in household appliances such as fans, air conditioners, and washing machines. These motors have two windings, the main winding, and the auxiliary winding. The main winding is designed to produce a magnetic field that rotates in one direction, while the auxiliary winding produces a magnetic field that rotates in the opposite direction. This results in a rotating magnetic field that is necessary for the motor to start and run.
To reverse the direction of rotation of a single-phase capacitor run induction motor, we need to reverse the direction of the magnetic field produced by the auxiliary winding. This can be achieved by interchanging the terminals of the auxiliary winding.
Interchanging the terminals of the AC supply or the capacitor will not reverse the direction of rotation of the motor. It will only result in the motor not starting or running at all.
Therefore, the correct answer is option 'C', interchanging the terminals of the auxiliary winding.
In summary:
- Single-phase capacitor run induction motors have two windings, the main winding, and the auxiliary winding.
- To reverse the direction of rotation, we need to reverse the direction of the magnetic field produced by the auxiliary winding.
- Interchanging the terminals of the AC supply or the capacitor will not reverse the direction of rotation of the motor.
- The correct answer is option 'C', interchanging the terminals of the auxiliary winding.
