Publication number: 20240159572Abstract: A resolver includes a rotor attached to a shaft of a rotating body, a stator, an excitation circuit, and an angle computation unit configured to compute a rotation angle of the rotor. Each tooth of the stator has line-symmetry with respect to a line connecting a center of a core back of the stator and centers of the teeth in a circumferential direction as viewed from an axial direction. A rotor outline is expressed by a function Rr(x(?), y(?)) defined by Equations (1) to (3), where an x and a y axes are axes of an orthogonal coordinate system having a center of the shaft as an origin, and an angle from a reference axis is ?, where a minimum distance from the center of the core back to the teeth is Ri, and a maximum distance is Ro, and a number of salient poles of the rotor is Nx.Type: ApplicationFiled: April 15, 2021Publication date: May 16, 2024Applicant: Mitsubishi Electric CorporationInventors: Hiroko IKEDA, Shohei FUJIKURA, Kenta MOTOYOSHI, Yu HIROTANI, Hidenori SASAKI, Tatsuya MORI
