MAGNETIC CORE, STATOR ASSEMBLY, ROTATING ELECTRICAL MACHINE, AND BRUSHLESS MOTOR

Abstract: a magnetic core that includes: a core back portion; and a tooth portion including: a tooth main-body portion extending from the core back portion in a first direction, and a tooth distal-end portion at a distal end of the tooth main-body portion in the first direction. a position of a geometric center of the tooth portion is the same as a position of a geometric center of the core back portion in a second direction, and when an orthogonal projection of the first direction onto a plane orthogonal to the second direction is a third direction, and a line connecting geometric centers of cross sections of the tooth main-body portion perpendicular to the third direction is a first line, a position of the first line at the distal end differs in the second direction from a position of the first line at an opposite end of the tooth main-body portion.
