Maximum Efficiency Drives of Interior Permanent Magnet Synchronous Motor Considering Iron Loss and Cross-Magnetic Saturation John B. Adawey, Shu Yamamoto, Takashi Kano, and Takahiro Ara Department of Electrical Engineering, Polytechnic University, Sagamihara, Kanagawa, Japan Abstract-- This paper covers the proposed method to maximize the driving efficiency for interior permanent magnet synchronous motors considering iron loss and cross-magnetic saturation effects. Using a simple repetition calculation method, the proposed method automatically determines the optimum current command in real-time. This method not only maximizes the driving efficiency but also realizes high-precision torque control performance. The validity of this method is verified from experimental results. Index Term -- Iron loss, magnetic saturation, maximum efficiency drive, optimum current command, torque control performance. INTRODUCTION Energy conservation is the primary goal and general objective of our latest research development in the field of electrical machines and system. From the perspective view of effective and efficient utilization of electrical energy, an essential technological issue to consider is to drive the machine at its maximum efficiency. Permanent Magnet Synchronous Motors (PMSM) are widely used in hybrid electronic vehicles, robotics, servo system, and other high-performance industry applications. Maximum efficiency drives of PMSM can be realized by the loss minimization control strategies. Loss minimization controllers of IPMSMs are roughly divided into search controllers and loss-model based controllers. The former is the search control algorithm method [1]-[3] where the current command vector is generated so that input power is minimized. In this method, motor constants are unnecessary but the pulsation is superimposed to the d- and q-axis currents during steady-state conditions. On the other hand, the latter which is the loss-model control method [4]-[9] u
