Technology on how to raise the performance of home appliances as air conditioner, washing machine and the like, such as high efficiency, low vibration, low noise, etc., is making progress recently. To model and simulate MCU/Inverter/Motor have been tried to apply into motor development as one of these energy-saving key technologies. Wherein, with applying an IPM (Interior Permanent Magnet) Motor as a motif, to analyze and simulate with both MATLAB and JMAG-RT can obtain the same results with real object, i.e. the current is warped by means of current phase.
In consequence, an analyzing model which can simulate synthetically with considerations of motor magnetic circuit, inverter, and software implemented in MCU is obtained.
