Title:
ROTARY MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/162232
Kind Code:
A1
Abstract:
A rotary motor (10) is provided with: a magnetic field element (40) having a magnet part (1000) which includes a plurality of magnetic poles, the polarities of which alternate in the circumferential direction; and an armature (50) having a multi-phase armature winding (51) disposed so as to face the magnet part in the radial direction. The magnet part is an oriented magnet in which a magnet magnetic path has been formed along a magnetization easy axis, and the magnetization easy axis has an angle of inclination within a prescribed angle range relative to the d-axis at at least at a point of intersection (P1) between the d-axis, which is a magnetic pole center, and an armature-side circumferential surface (1002) of the magnet part.
