Abstract
A stator has multi-phase stator coils that are wound around a stator core by concentrated winding. A rotor has rotor coils that are wound at multiple portions of a rotor core in the circumferential direction and diodes that serve as rectifier unit that is connected to the rotor coils and that varies the magnetic characteristics of the respective rotor coils alternately in the circumferential direction. A rotary electric machine driving system includes a decreasing/increasing pulse superimposing unit that superimposes decreasing pulse current for a pulse-shaped decrease on a q-axis current command for passing currents through the stator coils and that superimposes increasing pulse current for a pulse-shaped increase on a d-axis current command.
