Document Type and Number:
Japanese Patent JP2017042007
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor capable of accurately detecting magnetic fluxes of permanent magnets of a rotor.SOLUTION: A motor 1 comprises: a stator 2 including an A-phase stator part 2a and a B-phase stator part 2b, in an axial direction, including first and second stator cores 4 and 5 including first and second claw-shaped magnetic poles 4b and 5b including radial extension parts 4c and 5c extending in a radial direction and magnetic pole parts 4d and 5d extending from distal ends of the radial extension parts 4c and 5c in the axial direction, and a winding 6 that is provided between the first and second stator cores 4 and 5; a rotor 3 including an A-phase rotor part 3a and a B-phase rotor part 3b, in the axial direction, including permanent magnets 12 opposing the magnetic pole parts 4d and 5d; and an A-phase sensor 21 and a B-phase sensor 22 provided between the permanent magnets 12 in the axial direction for detecting magnetic fluxes of the permanent magnets 12.SELECTED DRAWING: Figure 3
