Abstract: A control device of an electric motor that drives an axis influenced by gravity includes: a determination unit that determines whether an overrun operation to move past a target position of the axis is allowable; and a drive control unit that, in a case in which it is determined by the determination unit that the overrun operation is allowable and the axis is driven in an antigravity direction, controls driving of the electric motor so that, after the axis being driven to the overrun position past the target position in the antigravity direction, the axis is driven again in a gravity direction to stop at the target position.

Abstract: A first coil fixing component has a first body portion inserted into a first void portion formed between a coil and a first end surface of a tooth portion, a first convex portion inserted into a first concave portion of the tooth portion, and a first locking portion extending from an end on an inner side of a radial direction of the first body portion toward the opposite side of the first end surface to lock the coil. A second coil fixing component has a second body portion inserted into a second void portion formed between the coil and a second end surface of the tooth portion, a second convex portion inserted into the second concave portion of the tooth portion, and a second locking portion extending from an end on the inner side of the radial direction of the second body portion toward the opposite side of the second end surface to lock the coil. The second body portion has an elastic structure that exerts elastic force in an axial direction.

Abstract: A motor of the present invention includes a stator having windings. The stator includes: a cylindrical outer member; a mold resin portion that molds the windings with a resin; and a stress non-transmitting portion provided between the mold resin portion and the outer member so as not to transmit stress to the outer member due to shrinking of the mold resin portion or reduce the amount of transmitted stress.

A rotor has a generally annular supporting member; a plurality of shaft portions positioned on the supporting member in a circumferential direction at regular intervals, the shaft portions extending generally parallel to a rotation axis of the rotor; and a plurality of divided cores each having a hole portion which is fitted to each shaft portion. By annularly connecting the divided cores, a generally annular dividable core for the rotor is formed. Each divided core has connecting portions at both circumferential ends thereof, and each connecting portion is configured to be connected to a connecting portion of a neighboring divided core while the divided core is fitted to the shaft portion.
