Types of motors

Question 1

Is a motor where the current alternates direction and this creates the reversal of polarity, whether is takes place in the rotor or the stator

Answer 1

AC motor

Question 2

Is the first kind of electric motor which is typically 75-80% efficient. They work well at variable speeds and have a great torque.

Answer 2

DC motor

Question 3

a powerful motor which can be used with both AC and DC power.

Answer 3

Universal motor

Question 4

runs at synchronous speed and was developed in 1925

Answer 4

synchronous motor

Question 5

is a single phase AC motor. It has only one coil with the turning shaft in the center,a lag in the flux passing around the coil cause the intensity of the magnet to move around the coil

Answer 5

shaded pole motor

Question 6

Runs at a speed lesser than synchronous speed, and the rotating torque, and speed is governed by varying the slip

Answer 6

induction motor
