Title:
MOTOR SYSTEM, MOTOR, AND DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2014/097432
Kind Code:
A1
Abstract:
This motor system (110) is provided with the following: a motor (100) comprising a rotor (2) with rotor-side projecting sections (22) and a stator (3) with two sets of three-phase coils (34) wound around stator-side projecting sections (33); and a drive circuit (10) comprising two sets of three-phase drive circuits (10a , 10b). The stator-side projecting sections (33) comprise a first stator-side projecting section (33a) around which one of the two sets of three-phase coils (34) is wound, and a second stator-side projecting section (33b) around which the other set of coils is wrapped. When the center in the circumferential direction of the first stator-side projecting section (33a) and the center in the circumferential direction of the rotor-side projecting section (22) coincide, the center in the circumferential direction of the second stator-side projecting section (33b) and the center in the circumferential direction of the rotor-side projecting section (22) are offset from one another, making it possible to reduce torque ripple.
