Abstract

This paper deals with the magnetic model of an interior permanent magnet synchronous motor, whose parameters are computed using finite element analysis. As known, in unsaturated conditions the motor inductive parameters and flux linkage call be univocally determined. Conversely, under saturated operation, different choices may be adopted to define them. Various models are examined, with the purpose to individuate the most effective for a prediction of the motor and speed capability. Attention is devoted to the performance at base speed as well as in the flux-weakening region. Comparison with tests confirms the good agreement with the results obtained by finite element analysis.
