Title:
MOTOR AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/016026
Kind Code:
A1
Abstract:
A motor 10 has a stator core 21 of a stator 20 and a rotor 30. The stator core 21 has a first portion 210 and a second portion 220. The first portion 210 is constituted by laminating a plurality of soft magnetic material sheets. The second portion 220 has a greater sheet thickness than the soft magnetic material constituting the first portion 210, is made of an electrically conductive and nonmagnetic material, and includes a first member 221 having a load-side third surface 21c and a second member 222 having an anti-load-side fourth surface 21d. The rotor 30 is rotatably fixed such that magnetic flux flows into the stator core 21 of the stator 20, and has a load-side fifth surface 32a and an anti-load-side sixth surface 32b. The motor 10 satisfies at least one of a positional relationship in which the fifth surface 32a is positioned on the anti-load-side with respect to the third surface 21c, and a positional relationship in which the sixth surface 32b is positioned on the load side with respect to the fourth surface 21d.
