Which of the following motors may be operated on DC or single-phase AC supply at approximately the same speed and output?
Which of the following motors may be operated on DC or single-phase AC supply at approximately the same speed and output?
Right Answer is:
Universal motor
SOLUTION
Universal Motor:
- The motors which can be used with a single-phase AC source, as well as a DC source of supply and voltages, are called Universal Motor.
- It is basically a single-phase DC series motor.
- On reversing the polarity of the line terminals of a DC Series Motor, the motor will continue to run in the same direction.
- A universal motor is a commutation-type motor.
- The universal motor produces approximately the same speed and output when operated either on a direct or single-phase AC source.
