Abstract: A motor includes a stator including a stator core and teeth respectively protruding from the stator core, and coils respectively wound onto the teeth n (n is an integer of 1 or greater) turns including first to n-th turns. The coils are each made from a conductive member having a polygonal cross section. On a cross section obtained when one of the coils is cut in a corresponding one of directions of protrusion of the teeth from the stator core, the one of the coils includes a recess on at least either a first opposing surface representing an opposing surface to a corresponding one of the teeth or a second opposing surface representing an opposing surface to another one of the coils, which is wound onto adjacent one of the teeth. A space allowing refrigerant used for cooling the coils to pass through is provided between the recess and at least either the first opposing surface or the second opposing surface.

Abstract: A laser processing apparatus includes first and second laser oscillators that emit first and second laser lights (LB1), (LB2) having wavelengths different from each other, an optical fiber that guides first and second laser lights (LB1), (LB2), and laser head (50) configured to condense first and second laser lights (LB1), (LB2), respectively, at predetermined positions of a workpiece. Laser head (50) includes optical path difference generation unit (70) provided inside second housing (51). Optical path difference generation unit (70) is configured to make an optical path length of first laser light (LB1) inside second housing (51) longer than an optical path length of second laser light (LB2).

Abstract: First block (10) is provided with heat dissipator (50). Heat dissipator (50) is provided at an end part of first block (10) on the emission side of the laser light. Heat dissipator (50) extends forward beyond a light emitting surface of semiconductor laser element (40). The surface, of heat dissipator (50), facing the laser light is inclined so as to be more distant from center line L of the laser light toward the forward direction.

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.
