Title:
ROTARY ELECTRIC MACHINE DRIVING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/110883
Kind Code:
A8
Abstract:
A stator (12) has multi-phase stator coils (28u, 28v and 28w) that are wound around a stator core (26) by concentrated winding. A rotor (14) has rotor coils (42n and 42s) that are wound at multiple portions of a rotor core (16) in the circumferential direction and diodes (21n and 21 s) that serve as rectifier unit that is connected to the rotor coils (42n and 42s) and that varies the magnetic characteristics of the respective rotor coils (42n and 42s) alternately in the circumferential direction. A rotary electric machine driving system includes a decreasing 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 (28u, 28v and 28w).
