RESOLVER AND ROLLING BEARING DEVICE WITH RESOLVER

摘要

PROBLEM TO BE SOLVED: To attach a resolver stator to a case member without being affected by distortion and dimensional errors of the case member.;SOLUTION: A resolver 10 has a resolver stator 12 fitted into a cylindrical fitting part 25 of a case member 15. The resolver stator 12 has a plurality of teeth parts 46 around which a coil 43 is wound and is formed in an inner periphery at intervals, and includes a stator core 42 press-fitted into the case member 15. Further, the resolver stator 12 includes an insulating part 48 formed like a ring and interposed between the teeth parts 46 and the coil 43 to insulate them from each other and includes a pair of insulators 44 arranged on both side surfaces in an axial direction of the stator core 42. A plurality of groove parts 47 for suppressing the occurrence of distortion of the stator core 42 in a radial direction due to press-fitting are formed on an outer peripheral surface of the stator core 42 along the axial direction and at intervals in a circumferential direction.;COPYRIGHT: (C)2014,JPO&INPIT
