Slip Ring Wound Rotor Motor

As the motor accelerates.

Slip ring wound rotor motor.

The slip ring brushes made of graphite are connected to a resistive device such as a rheostat. 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. 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. Used sort by date added.

Each slip ring is connected to one of the three phases of rotor windings. A wound rotor motor uses three slip rings typically made of copper or a copper alloy mounted to but insulated from the motor shaft. The rotor is wound for the same number of poles as that of the stator. 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. 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. This type of rotor is provided with a 3 phase double layer distributed winding consisting of coils used in alternators.

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. Their sole purpose is to allow resistance to be placed in series with the rotor windings while starting figure below. Slip ring induction motor is one of the types of 3 phase induction motor and is a wound rotor motor type. 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.

Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit. As the slip rings turn with the. 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. In contrast a traditional induction motor aka squirrel cage motor has windings that are permanently short circuited by an end ring.
