ARMATURE CORE, ARMATURE, AND ELECTRIC MOTOR

摘要

An armature core (8A) includes a plurality of teeth (12) that radially extend. A plurality of coils (91), (92), and (93) are wound in a concentrated winding manner on a winding drum portion (12a) of each tooth; a winding wire (14) of a lowermost side of at least a first-layer coil is wound so as to come into close contact with a winding surface of a base end side of the winding drum portion; a second-layer coil, which is to be wound later, is wound so that at least a part of the second-layer coil overlaps the first-layer coil; and a step (12a1) as a regulating portion, which regulates the positional deviation of the winding wire of the lowermost side of the first-layer coil in an extending direction of the winding drum portion, is provided on at least a part of the winding surface for the first-layer coil on an outer periphery of the winding drum portion.
