要約(英語): This paper describes the starting characteristics with or without a starting circuit by comparing the analysis and experimental results. Based on the analysis results, the maximum phase current for the field circuit with the starting current is 17% less than that without the circuit. The time required by the circuit to achieve synchronous speed is 30% faster because of the starting circuit. In the motor without the starting field circuit, increased current and decreased acceleration are observed because of the braking torque. As the starting characteristics are considerably altered by the voltage drop and unbalanced three-phase voltage, these factors were considered in the analysis. From the experimental results, it was confirmed that the phase current and acceleration time agreed with the analysis results.
