Slip Ring Wound Rotor Motor

Adjusting the resistance allows control of the speed torque characteristic of the motor.

Slip ring wound rotor motor.

The slip ring brushes made of graphite are connected to a resistive device such as a rheostat. 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. Each slip ring is connected to one of the three phases of rotor windings. The slip ring induction motors usually have a phase wound rotor.

However no power is applied to the slip rings. As the motor accelerates. Slip ring induction motor is one of the types of 3 phase induction motor and is a wound rotor motor type. 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.

Sort by manufacturer sort by location sort new vs. Mon sep 21 2020 16 04 34. 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.

Definition of slip ring motor. The rotor is wound for the same number of poles as that of the stator. 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. Motors a c slip ring 60 cycle wound rotor motors a c slip ring 60 cycle wound rotor there are 258 listings in this category update.

As the slip rings turn with the. In contrast a traditional induction motor aka squirrel cage motor has windings that are permanently short circuited by an end ring. This type of rotor is provided with a 3 phase double layer distributed winding consisting of coils used in alternators. It consists laminated cylindrical core which has a semi closed slot at the outer periphery and carries three phase insulated winding.

A wound rotor motor uses three slip rings typically made of copper or a copper alloy mounted to but insulated from the motor shaft. Used sort by date added. Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit.
