B 4 poles
C 8 poles
D 2 poles​

Answer 1

Answer:

11. The number of the pole in Small Dc Motor Up to 5 H.P are

answer is A

Answer 2

The number of the pole in Small Dc Motor Up to 5 H.P are 2 poles.

Explanation:

The correct answer is option D) 2 poles​

• DC motor is a device that converts the direct current electrical energy to mechanical energy and then into a rotational force.
• All types of DC motors have some internal mechanism.
• Small hp motors require only two poles because the number of poles is inversely proportional to the speed; thus, a two-pole motor runs faster than a four-pole motor. The efficiency of a two-pole motor is higher. A two-pole motor has a higher rpm and a lower noise level.

A)  10 poles: The number of the pole in Small Dc Motor Up to 5 H.P are 2 poles. So this is considered as the wrong ansswer.

B) 4 poles: The number of the pole in Small Dc Motor Up to 5 H.P are 2 poles. So this is considered as the wrong ansswer.

C) 8 poles: The number of the pole in Small Dc Motor Up to 5 H.P are 2 poles. So this is considered as the wrong ansswer.
