2-Controllable-Rotor Motor Driven by a 5-Phase Current

A number of automobiles have been fitted with electric motors and their inverters. In order to reduce the space of the motors, we have proposed a 2-controllable-rotor motor which consists of 2 rotors and 1 stator. However, this motor is driven by a 6-phase inverter, and the inverter size is almost the same as that for 2 motors driven by 3-phase inverters. In this paper, we propose a 2-controllable-rotor motor driven by a 5-phase current, and its operation principle is described. Furthermore, its characteristics are investigated using finite element analysis.
