Traditional induction motor models are either 60-Hz models for steady-state operation or dq0 models for transient analysis. This paper presents a general induction-motor model based directly on phase coordinates. Stator and rotor windings are seen as coupled coils, much like a transformer. For transient analysis, this model is basically the same (apart from the mechanical equations) as the standard model for coupled inductances in the EMTP. In addition to the general model equations, the paper presents the data conversion procedure to obtain the model parameters from standard manufacturers data. Simulation results show the validity of the model as compared to a standard (dq0) EMTP induction motor model
