Document Type and Number:
WIPO Patent Application WO/2024/029273
Kind Code:
A1
Abstract:
[Problem] To reduce magnetic flux interlinking with stator windings by effectively shielding magnetic flux that is generated by a rotating electrical machine. [Solution] Provided is a stator 100 of a resolver 1, comprising: a stator core 110 including a core back portion 111, and teeth 112 extending radially inward from a peripheral edge of the core back portion 111; an insulator 120 provided on the stator core 110; stator windings 130 wound around the teeth 112 via the insulator 120; and a shield 160 having an annular shape and covering a motor side of the stator core 110. The insulator 160 includes a winding portion that is attached to the teeth 112, and a flange portion 125 extending radially outward from the winding portion. The shield 160 includes a first annular portion 161 that covers the core back portion 111, and a second annular portion 164 that covers the stator windings 130. The flange portion 125 is interposed between the core back portion 111 and the first annular portion 161.
