This external circuit helps in developing a high starting torque compared to a squirrel cage type.
Rotor slip ring induction motor diagram.
The slip ring induction motor has two distinctly separate parts one is the stator and other is the rotor.
It consists laminated cylindrical core which has a semi closed slot at the outer periphery and carries three phase insulated winding.
Characteristics of slip ring induction motor.
Slip ring induction motor is one of the types of 3 phase induction motor and is a wound rotor motor type.
The motor which employing the wound rotor is known as a slip ring induction motor or phase wound motor.
The rotor is wound for the same number of poles as that of the stator.
It is a type of motor where its external circuit is connected using some rings.
A wound rotor motor also known as slip ring rotor motor is a type of induction motor where the rotor windings are connected through slip rings to external resistance.
An induction motor is an electrical device that converts electrical energy into mechanical energy.
Adjusting the resistance allows control of the speed torque characteristic of the motor.
It is most widely used for industrial applications due to its self starting attribute.
Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit.
This rings attached with high resistance acts as an external circuit for the rotor.
The stator circuit is rated as same in the squirrel cage motor but the rotor is rated in frame voltage or short circuit current.
