Slip ring Induction Motor, How does it work?

 Slip ring Induction Motor, How does it work?

Induction motors have been ruling the industrial world for many decades. In the induction motors used in lift and hoists, you will see a type of rotor called a slip ring rotor, whereas in most of the other applications you will see a simpler, squirrel cage type of rotor. Why are there two different designs of rotor construction for induction motors? We will explore this in the video.

A slip ring induction motor, also known as a wound rotor induction motor, is a type of induction motor that has three-phase windings on the stator and a rotor with slip rings and brushes to allow external resistance to be connected in series with the rotor windings. This allows for the control of the rotor speed, which can be adjusted to optimize the motor's performance and efficiency.

The principle of operation of a slip ring induction motor is similar to that of a standard induction motor, with the main difference being the ability to control the rotor speed. The stator windings produce a rotating magnetic field that induces current in the rotor windings. As the rotor speed is less than the stator speed, a slip occurs between the two. By adding external resistance to the rotor circuit, the rotor speed can be adjusted to match the stator speed, thus reducing slip and increasing efficiency.

Slip ring induction motors are widely used in industrial applications such as fans, pumps, compressors, and conveyors, where variable speed control and high torque are required. They are also used in variable frequency drive applications.

The main advantage of a slip ring induction motor is its ability to operate at variable speeds, which allows for better control and optimization of the motor's performance and efficiency. Additionally, slip ring induction motors have a high starting torque, which makes them suitable for applications that require high torque at low speeds.

The main disadvantage of a slip ring induction motor is that they require regular maintenance of the slip rings and brushes, which can be a source of electrical noise, and can cause wear and tear over time. Additionally, the slip ring induction motor is more complex and expensive compared to the squirrel cage induction motor.
