• Characteristics analysis using the matrix method of stator-fed AC commutator motor are presented. Recently, many variable-speed AC motor drive systems with semiconductor switching devices have been developed. However, the power supply systems suffer from higher harmonic currents during switching. On the contrary, three-phase AC commutator motors have essentially no detrimental influence on the power supply systems. Consequently, the motors are being reconsidered for use in spite the fact that they need periodic maintenance for the replacement of commutators and brushes.So far, motor analysis was calculated using various vector methods: in this case complicated calculations are required, with accurate solutions difficult to be obtained. We derive the fundamental equations using the matrix method which can be applied to the transient phenomenon. Also, we obtained an agreement between calculations and experimental results of the steady-state characteristics.
