Title:
MOTOR AND ROBOT
Document Type and Number:
Japanese Patent JP2022116601
Kind Code:
A
Abstract:
To facilitate positioning when a stator of a motor is composed of a plurality of magnetic circuit members, and does not hinder formation of a magnetic flux.SOLUTION: A stator is formed by combining a plurality of magnetic circuit members in a circumferential direction of a stator. This magnetic circuit member includes a partial yoke that forms a yoke, and first and second partial cores that are formed at each circumferential end of the partial yoke and form a part of the core. This magnetic circuit member is placed in a case provided with a positioning convex portion at a position corresponding to an end position of the partial yoke. At this time, the stator is formed by combining the first partial core of the magnetic circuit member and the second partial core of an adjacent magnetic circuit member in the circumferential direction such that the first partial core is brought into contact with the second partial core. The positioning of the magnetic circuit member with respect to the case is performed by assembling a concave portion provided at the end portion of the partial yoke in the circumferential direction of the magnetic circuit member with the convex portion on the case.SELECTED DRAWING: Figure 5
