Question

What is a special type of motor designed to operate with the rotor stalled without damage to the motor?

Answer 1

Answer:

Torque motor

Explanation:

• A special type of motor that is designed to operate even when the rotor is stalled is called a torque motor and it does not incur any damage while doing so.

• These motors have a toroidal construction and are induction motors.

• They have a wide diameter which allows them to have a higher torque and thus, this improves their thermal performance and this enables the motor to keep working even when it is stalled as it can draw high currents.

• Further, these motors are usually present without brushes or commutators due to which they can operate at higher speeds.

• A torque motor is most commonly found in tape recorders, computer games, throttle controls and actuators.
