This construction of the rotor is aimed at reducing the phase difference.
Slip ring rotor winding.
As the motor accelerates.
These slip rings are insulated from the rotor shaft.
Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit.
Rotor the rotor of a squirrel cage motor is a set of bars which are short circuited by end rings.
A wound rotor motor uses three slip rings typically made of copper or a copper alloy mounted to but insulated from the motor shaft.
A motor with a wound type rotor is known as a slip ring induction motor.
Let s see how the slip ring rotor does it.
Name one disadvantage of slip ring induction motor and squirrel cage induction motor.
For ease of understanding instead of the current 24 slots winding let s use a 12 slot winding.
The slip ring brushes made of graphite are connected to a resistive device such as a rheostat.
However the rotor construction of the slip ring motor is quite interesting.
Each phase of winding is connected with the slip ring.
What is a slip ring induction motor.
This has to do with the windings on the rotor and the use of slip rings.
Construction the construction of the slip ring motor is more complicated than the squirrel cage.
Bar straps or wires are used for winding.
The disadvantages are high copper losses and the low torque.
As it names wound rotor the rotor is wound with a 3 phase windings.
Also rotor windings are connected through slip rings to external resistance.
A large number of rotor turns will increase the secondary voltages and reduce the current that flows through slip 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.
Instead of bars in this motor three windings are used.
