Slip Ring Motor

Slip Ring Motor. A wound rotor induction motor (also known as a would round motor or slip ring induction motor) is defined as a special type of 3 phase AC induction motor designed to provide high starting torque by connecting an external resistance to the rotor circuit The motor’s rotor is a type of wound rotor Hence why it is also known as a wound rotor or phase wound induction.

Replace your brush or precious metal slip ring with superior Rotating Electrical Connectors from Mercotac Inc Made in USA Slip rings need continual maintenance to avoid degradation of the rotating electrical connection caused by normal wear and debris Even precious metal slip rings limit rotational speed and increase electrical noise and resistance with wear When you replace.

Rotor Resistance or Slip Ring Motor Starter This type of motor starter works on a full voltage motor starting technique It works only on a slip ring induction motor that is why it is also known as a slip ring motor starter External resistances are connected with the rotor in star combination through the slip ring These resistors limit the rotor current & increase the torque This in turn.

PDF fileChanging Rotor Slip Important to match the motor to the load ensure that a change in motor power gives a desired change in load speed Load should have a substantial inertial components inertial torque can “carry” the load through brief periods when motor torque cannot Best used with motors designed for high slip Variable Series Resistance Additional series resistance reduces.
