Slip ring induction motor explained

Slip Ring in Motors A form of the three-phase induction motor known as a slip ring induction motor, also known as a wound rotor motor, is made to deliver strong beginning torque for loads with high inertia while using little starting current.

A conventional squirrel cage induction motor's stator is equivalent to that of a slip ring motor. The rotor, on the other hand, is unique because it features a three-phase winding with independent slip rings attached to each terminal.

Through carbon brushes, which can have series connections of resistors inside of them, the slip rings are connected to an external secondary circuit.

Fabcouniversal is a carbon brush manufacturer in Delhi NCR.

High torque results from the rotor current running more in phase with the stator current as a result of the greater resistance. You have a low starting current in addition to a very high starting torque. Slip Ring in Motors are mostly utilised for loads with large moments of inertia and load torques in the high power range. These motors are also used in new facilities, particularly at operating voltages starting at 6000 V and powers starting at about 600 kW. Slip-ring induction motors demonstrate their benefits in this situation since big converters are unfavourable in weak power networks.
