Abstract

PURPOSE:To reduce cogging torque by cutting angles of both ends of each addendum of an armature core. CONSTITUTION:An armature is provided to the inside perimeter of a motor. An outside diameter R1 of a tooth 14 forming the side wall of each slot 16 of the armature core 12 is placed at a virtual circle 22. Angles of the tip ends of each tooth 14 are cut off, and a cut slope 20 after cutting off is placed at the inside of the virtual circle 22 of the outside diameter R1.
