Slip Ring Wound Rotor Motor

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.

Because of various advantages like low initial current high starting torque and improved power factor it is used in applications that require high torque cranes and elevators. In contrast a traditional induction motor aka squirrel cage motor has windings that are permanently short circuited by an end ring. Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit.

The rotor core is made up of steel laminations which have slots to accommodate formed 3 single phase windings. The motor which employing the wound rotor is known as a slip ring induction motor or phase wound motor. Their sole purpose is to allow resistance to be placed in series with the rotor windings while starting figure below. This type of rotor is provided with a 3 phase double layer distributed winding consisting of coils used in alternators.

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 rotor is wound for the same number of poles as that of the stator. Used sort by date added. As the motor accelerates.

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. The slip ring brushes made of graphite are connected to a resistive device such as a rheostat. Sort by manufacturer sort by location sort new vs. A wound rotor motor uses three slip rings typically made of copper or a copper alloy mounted to but insulated from the motor shaft.

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

Each slip ring is connected to one of the three phases of rotor windings. Mon sep 21 2020 16 04 34. It consists laminated cylindrical core which has a semi closed slot at the outer periphery and carries three phase insulated winding.
