Double independent three-phase winding permanent-magnet synchronous motors with iron loss: Dynamic mathematical model and vector simulator

This paper proposes a new dynamic mathematical model for double independent three-phase winding permanent-magnet synchronous motors (PMSMs) with iron loss. The proposed model is constructed in the general reference frame, and consists of three consistent basic equations, namely circuit equation, torque evolution equation, and energy transmission equation. In addition to the mathematical model, this paper proposes two new vector simulators for the PMSMs. They are constructed in the general reference frame, and can be quickly reduced to the stator or rotor reference frame. The proposed mathematical model and vector simulator are inevitable and useful for characteristic analyses, drive system developments, etc., for the PMSMs driven in the high-speed region, where iron loss is the dominant factor of total losses. © 2018 The Institute of Electrical Engineers of Japan.
