Which DC motor is preferred for Elevator?
Which DC motor is preferred for Elevator?
Right Answer is:
Cumulative compound motor
SOLUTION
- Compound motor finds applications where high starting torque or pulsating load are required.
- In the elevator, the load is always pulsating and high starting torque is required to run the elevator.
- This high starting torque is provided by the series winding of the compound motor and maximum speed at no load is limited by shunt winding of the compound motor.
