The CIM6 induction motor model represents an induction machine that can be either model a single or double cage motor. The model can represent two distinct impedance circuits depending on the selected type.
The load torque equation for the CIM6 motor model is defines as:
TL = T(Aw^2 + B*w + C0 + Dw^E)
The modelling of such devices is based, mainly, on the following references:
Siemens: "PSS®E Model Library" [PSSE-MODELS].
PowerWorld: Load Characteristic Models [PSSEMotor].
