Dynamic Model of 3-ph IM in synchronously rotating reference frame

Induction motor modelling using synchronously rotating reference frame.

The mathematical model of Induction motor in synchronously rotating reference frame. Reference frame speed is equal to synchronous speed(ω= ωe). Synchronously rotating reference frame is suitable when analog computer is employed because both stator and rotor d-q quantities becomes steady DC quantities. It is also best suited for studying multi-machine system.
