Slip Ring Wound Rotor Motor

The stator of a wound rotor motor is the same as a typical induction motor but the rotor has a three phase winding with each of the winding terminals connected to separate slip rings.

Slip ring wound rotor motor.

This type of rotor is provided with a 3 phase double layer distributed winding consisting of coils used in alternators. Mon sep 21 2020 16 04 34. A wound rotor motor uses three slip rings typically made of copper or a copper alloy mounted to but insulated from the motor shaft. However no power is applied to the slip rings.

It consists laminated cylindrical core which has a semi closed slot at the outer periphery and carries three phase insulated winding. Adjusting the resistance allows control of the speed torque characteristic of the motor. Each slip ring is connected to one of the three phases of rotor windings. A wound rotor induction motor has a stator like a squirrel cage induction motor but a rotor with insulated windings brought out via slip rings and brushes.

The rotor is wound for the same number of poles as that of the stator. The slip ring induction motors usually have a phase wound rotor. The slip ring brushes made of graphite are connected to a resistive device such as a rheostat. In contrast a traditional induction motor aka squirrel cage motor has windings that are permanently short circuited by an end ring.

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. Slip ring induction motor is one of the types of 3 phase induction motor and is a wound rotor motor type. Definition of slip ring motor. As the slip rings turn with the.

The rotor core is made up of steel laminations which have slots to accommodate formed 3 single phase windings. Slip ring or wound rotor three phase induction motor in this type of three phase induction motor the rotor is wound for the same number of poles as that of the stator but it has less number of slots and has fewer turns per phase of a heavier conductor. The motor which employing the wound rotor is known as a slip ring induction motor or phase wound motor. Used sort by date added.
