Document Type and Number:
Japanese Patent JP6672914
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor capable of achieving high-speed rotation while suppressing the reduction in torque.SOLUTION: A rotor 21 includes: magnet magnetic poles Mn, Ms comprising permanent magnets 22; and a non-magnet magnetic pole section 25 of a rotor core 23 which opposes U-phase windings U2, U4 at a rotational position of the rotor 21 where the magnet magnetic pole Mn (or the magnet magnetic pole Ms) opposes, for example, U-phase windings U1, U3. The non-magnet magnetic pole section 25 of the rotor core 23 includes: core magnetic poles Cn, Cs that function as an opposing magnetic pole to the magnet magnetic poles Mn, Ms by the magnetic fluxes of the magnet magnetic poles Mn, Ms; and a core section 28 between slits (magnetic flux permitting section) which permits the generation of an interlinkage magnetic flux (weak field magnetic flux) arising as a result of a weak field current in an opposing windings 13.SELECTED DRAWING: Figure 1
