This paper describes an impact of a flux weakening current to an iron loss which includes a modulation index effect and PWM carrier effect. 1.5 kW IPMSM was selected as a test machine, the measured iron loss are analyzed and compared with the simulation results which are obtained by a coupled simulation between FEA and circuit simulator. Interesting results are shown in this paper such that the iron...
This paper compares SPMSM and IPMSM under high flux density condition. Both machines use same stator construction and same rotor geometry, also have similar open circuit voltages. No load characteristics which include iron loss are compared and output power characteristics which include efficiency and iron, eddy current loss are described.
