Slip Ring Wound Rotor Motor

As the slip rings turn with the.

Slip ring wound rotor motor.

Their sole purpose is to allow resistance to be placed in series with the rotor windings while starting figure below. 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. 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.

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. Adjusting the resistance allows control of the speed torque characteristic of the 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. The slip ring induction motors usually have a phase wound rotor.

It consists laminated cylindrical core which has a semi closed slot at the outer periphery and carries three phase insulated winding. 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. The rotor is wound for the same number of poles as that of the stator. Sort by manufacturer sort by location sort new vs.

The rotor core is made up of steel laminations which have slots to accommodate formed 3 single phase windings. However no power is applied to the slip rings. As the motor accelerates. In contrast a traditional induction motor aka squirrel cage motor has windings that are permanently short circuited by an end ring.

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. Used sort by date added. Mon sep 21 2020 16 04 34. Each slip ring is connected to one of the three phases of rotor windings.

Definition of slip ring motor. The slip ring brushes made of graphite are connected to a resistive device such as a rheostat. Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit.
