Slip Ring Motor

A slip ring motor is a type of electric motor that utilizes slip rings to transmit electrical power to the rotor. These motors are mainly used in applications where high torque is required during startup or under varying load conditions. The slip rings allow for continuous electrical contact between the stationary and rotating parts of the motor, which helps in providing power to the rotor.

Key Features of Slip Ring Motors:

1. Slip Rings: The motor is equipped with slip rings and brushes, which ensure continuous power transmission from the stationary part of the motor to the rotating rotor.

2. High Starting Torque: Slip ring motors are known for their ability to deliver high starting torque compared to other types of motors, like squirrel cage motors.

3. Speed Control: Slip ring motors offer better speed control and torque regulation, making them suitable for heavy-duty applications.

4. External Resistor Control: The external resistors can be added to control the motor’s speed and provide better starting conditions.

Applications:

Slip ring motors are used in a variety of applications where high torque and control are critical. These include:

– Cranes and hoists

– Rolling mills

– Ventilators

– ConveyorsBrush motor technology

– Pumps
