Answer 2

Answer:

The correct answer is Option $4$: all of the above.

Explanation:

1. Construction-wise, induction motors are simple and robust. The strength and adaptability of induction motors allow them to function in any environment.
2. As a result of the absence of brushes, commutators, and slip rings, induction motors are less expensive.
3. Due to the lack of brushes, commutators, and slip rings, they require no maintenance, in contrast to dc motors and synchronous motors.
4. As induction motors don't have brushes, which can produce sparks, they can be used in noxious and explosive settings.
5. Induction motors are made to rotate utilizing various auxiliary because they lack self-starting torque.

Due to their benefits, induction motors are becoming more common in household and commercial settings.
