Fundamental Wave AIM Slip Ring

Asynchronous Induction Machine with Slip Ring Rotor  Description

The Fundamental Wave AIM Slip Ring (or AIM Slip Ring) component models an asynchronous induction machine with a slip ring rotor. Resistances and stray inductances of the machine always refer to either stator or rotor. The symmetry of the stator and rotor is assumed. The number of stator and rotor phases may be different. The following losses are modeled:

 • heat losses in the temperature dependent stator winding resistances
 • heat losses in the temperature dependent rotor winding resistances
 • friction losses
 • stator and rotor core losses (only eddy current losses, no hysteresis losses) Connections
