This paper presents the new scheme for high-efficiency operation of PWM inverter-driven hysteresis motor with short-duration overexcitation. When the terminal voltage Vi of the hysteresis motor running at synchronous speed is continuously increased up to nVi (n > 1) and then continuously decreased to Vi, input currents are reduced and output power is increased at the same time. Because of this,...
This paper presents the method to determine the optimum values of the capacitance and rotor-slot skew pitch to maximize the efficiency of a single-phase capacitor-run permanent-magnet motor using the time-stepping finite element analysis and response surface methodology. The optimum values of the capacitance and rotor skew pitch to maximize the efficiency at the rated voltage and output are obtained...
