The correct answer is: D. It is not easily reversed.
A repulsion-start induction motor is a type of electric motor that uses a combination of repulsion and induction principles to start and run. It has a stator with windings that are connected to an AC power source, and a rotor with windings that are not connected to the power source. When the motor is turned on, the stator windings create a magnetic field that induces a current in the rotor windings. This current creates its own magnetic field, which interacts with the stator field to cause the rotor to turn.
Repulsion-start induction motors are relatively inexpensive and easy to maintain. They are also relatively efficient and have a good power-to-weight ratio. However, they do have some disadvantages. One disadvantage is that they make quite a bit of noise on starting. Another disadvantage is that they are not easily reversed.
To reverse a repulsion-start induction motor, you need to change the polarity of the stator windings. This can be done by using a switch or a reversing starter. However, this is a relatively complex procedure and should only be done by qualified personnel.
In conclusion, the correct answer to the question “Which of the following statements regarding repulsion-start induction motor is incorrect?” is D. It is not easily reversed.
