Which type of bearing is provided in small induction motors to support the rotor shaft ?
Correct answer: A. Ball bearings
- A. Ball bearings
- B. Cast iron bearings
- C. Bush bearings
- D. None of the above
Explanation
Small induction motors commonly use ball bearings to support the rotor with low friction and maintain alignment. Bush or sleeve bearings are used in some simple, low-cost appliances but are not the standard answer for small induction motors.
