Unformatted text preview: Circuit Model for Operation of 3-Phase Synchronous Permanent Magnet Motor in Transients (Dynamics) 1. Circuit model The motor circuit model is shown in Fig.1. The circuit parameters are set up under the following assumptions: • All elements of the motor are linear and no core losses are considered, • Electromotive forces vary sinusoidally with the rotational electric angle ϕ e • Due to the surface mounted permanent magnets winding inductances are constant (do not change with the ϕ e angle).
