Abstract: A motor includes a stator core, teeth respectively protruding from the stator core, and coils respectively wound onto the teeth n (n is an integer of 2 or greater) turns including first to n-th turns. Within each of ranges respectively wound with the coils onto the teeth in directions of protrusion of the teeth from the stator core, the first turn of each of the coil lies adjacent to a center of the motor. A k-th (k is an integer, 1

Abstract: A coil includes a series of turns constituted by a first turn to an n-th turn of a conductive wire having a quadrangular cross-section, where the conductive wire is wound in a spiral shape and is stacked in a vertical direction, and n is an integer equal to or greater than 3. In addition, at least a part of the conductive wire of the first turn to the n-th turn is provided with a deformed part whose shape is different from shapes of the other parts. Further, the first turn and the n-th turn are on the both end parts of the series of turns. In addition, at each of the first turn and the n-th turn, the deformed part makes an outer surface positioned on an opposite side with respect to a center of the series of turns extend in a flush manner along a plane intersecting the series of turns.

Abstract: The invention provides a connection structure between a coil and a bus bar attached to a stator of a motor, and the coil and the bus bar each include a lead part. At least one of the lead parts has a distal end provided with a corner cut away to be stepped to configure a stepped portion having a side surface extending substantially in parallel with a longitudinal direction of the lead part. The coil and the bus bar are connected to each other in a state where the side surface of the stepped portion of a first one of the lead parts is in contact with a second one of the lead parts.
