The efficiency-oriented control strategies are very important to obtain high-efficiency performance of permanentmagnet synchronous motor (PMSM) drive systems. This paper proposes a novel analytic system loss model of PMSM drive system which can consider about both losses of PMSM and power converter losses. The losses of PMSM consist of two parts: stator iron losses and stator copper losses which...
As the permanent magnet synchronous motor (PMSM) system is the key part of power system in electric vehicles (EVs), the efficiency of PMSM system has great influence on the energy consumption of EVs. To increase the endurance mileage of EVs in one charge, it is important to improve the system efficiency of PMSM drive system. This paper proposes a novel analytical nonlinear loss model for PMSM system...
Double-side tabular permanent magnet linear synchronous motors (PMLSM), which is incorporated with high power pulse technology, so as to be high power pulsed-PMLSM (PP-PMLSM), is mainly applied in the aspect of short-term acceleration. Under large current, the motor generates high instantaneous thrust and accelerates the load immediately to the expected velocity. The high winding current density and...
