Title:
ROTARY ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2012/081392
Kind Code:
A1
Abstract:
Provided is a rotary electrical machine capable of providing a strong magnetic flux when the rotational device is operated at maximum magnetic flux, and of favorably suppressing magnetic flux when in a relatively weak field state. Magnetic pole ends (FT) of a plurality of permanent magnets (24) are disposed at both ends in the circumferential direction of each magnetic pole (F) formed by the permanent magnets (24), and are disposed closer to a subrotor (10) than connecting ends (FA). The magnetic pole width (M1) is the distance in the circumferential direction between each magnetic pole end (FT) of each magnetic pole (F) on a surface of a main rotor (20) facing the subrotor (10), and the magnetic pole interval (M2) is the distance in the circumferential direction between magnetic pole ends (FT) of magnetic poles (F) adjacent in the circumferential direction. The rotor-side magnetic resistor width (S1) is the range in the circumferential direction in which a magnetic resistor (7) is provided on a surface of the subrotor (10) facing the main rotor (20). The plurality of permanent magnets (24) is disposed so that magnetic pole interval (M2) is less than magnetic pole width (M1), and the magnetic resistor (7) is formed so that rotor-side magnetic resistor width (S1) is equal to or greater than magnetic pole interval (M2) and less than magnetic pole width (M1).
