Analysis of characteristics of 3-phase synchronous inductor motor

This paper treats the 3-phase synchronous inductor motor of the same structure as the PM type or HB (hybrid) type 3-phase stepping motor. The characteristics of the synchronous inductor motor when it is driven by a single-phase power supply using a phase shifting capacitor are analyzed. Motor performance is examined in the connection with the capacitance of capacitor, and the selecting method of capacitance for obtaining good performance is proposed. Effects of motor constants on the characteristics of the motor are discussed. Moreover, starting characteristics of the motor driven by a single-phase power supply are also examined.
