Embodiment Construction

[0039] In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown schematically in order to simplify the drawings.

[0040] First, the basic idea in this embodiment will be described. The present embodiment relates to a frame structure of a motor whose rotor has a magnetic field source including a magnet. In the following description, since the structure and function of a motor having a magnetic field source including a magnet as a rotor are well known, detailed description will be omitted except for the parts related to the present embodiment.

Abstract

The invention provides a frame structure of a motor and a method for manufacturing the frame and the armature of the motor. In a frame structure of a motor, when the number of angles of a frame is 4M (M is a natural number, and M >= 1), and the number of slots of an armature core is 6N (N is a natural number, and N >= 1), the armature core is inserted into the frame in such a manner as to form a variation theta within a predetermined range in a circumferential direction between a reference line that is orthogonal to two opposing sides of the frame and passes through a rotation axis of the frame, and a straight line linking magnetic poles symmetric about a point with respect to the rotation axis.

Description

[0001] Cross References to Related Applications [0002] This application is based on Japanese Patent Application No. 2019-235835 filed with the Japan Patent Office on December 26, 2019, and the entire content of said Japanese Patent Application is hereby incorporated by reference. technical field [0003] The invention relates to a motor frame structure and a manufacturing method of the motor frame and armature. Background technique [0004] A synchronous motor including permanent magnets is an example of a motor whose rotor has a magnetic field source including magnets. In this synchronous motor including permanent magnets, due to changes in the reluctance of the armature core and changes in the magnetic flux density of the permanent magnets, even in a no-load state, a torque that pulsates according to the rotation angle of the rotor, that is, a tooth slot torque. Regarding the cogging torque, a cogging torque caused by a "design factor" and a cogging torque caused by a ...
