Summary:This paper describes a vector control method of a magnetically modulated motor. The motor has a quite different structure from a standard permanent magnet synchronous motor (PMSM) because of the two rotors with two different mechanical output shafts, i.e., an inner PM rotor and an outer magnetic-flux modulator composed of only iron and air. Investigation on the vector control method using a real machine is still unexplored, thus, the paper discusses the vector control algorithm of the motor. In addition, several experimental tests have been conducted to examine the control performance of the mechanical output power delivered by the two rotors, using a prototype machine. It has been verified that the discussed algorithm makes it possible to control the two rotor output power as well as the stator input power like a conventional planetary-gear-based HEV system, including the motoring and regenerating operations.
