Abstract
This paper proposes a performance analysis of a modified three-phase induction motor with optimal capacitance operating with a singlephase mains supply. The modified three-phase motor is described and analyzed. Based on analytical equations, calculation of optimal capacitance to minimize voltage unbalance and torque pulsations is performed. Moreover positive and negative components of voltages are revealed. A d-q-0 reference frame for dynamic performance analysis is used to investigate flux linkages and electromagnetic torque. The validity of the optimal capacitance is confirmed by experimental results, showing that the motor has the least voltage unbalance and the highest efficiency compared with other non-optimal capacitances. The experimental and simulation results are in good agreement.
