    Abstract: A flying device includes a plurality of rotary vanes, a motor element serving as a driving source for each of the plurality of rotary vanes, the motor element driving and rotating a main shaft of the rotary vanes, and a drive circuit. The motor element includes a stator, a rotor, and a pair of bearings. The stator includes a stator core having an annular yoke and a plurality of teeth projecting inward from the annular yoke, and stator windings wound respectively around the plurality of teeth of the stator core. The rotor includes a permanent magnet of a cylindrical shape located inside the stator core via a gap, the permanent magnet being positioned counter to the plurality of teeth, a rotor yoke in contact with a cylindrical inner wall surface of the permanent magnet, and a shaft pivotally supported at an axis of the rotor yoke, the shaft being connected to the main shaft. The pair of bearings pivotally support the shaft to allow the shaft to rotate freely, and are located respectively on both sides of a direction of a rotating shaft of the rotor. The permanent magnet has anisotropically arranged magnetic poles, and a number of the magnetic poles is P representing an even number. The permanent magnet is configured such that the rotor yoke is smaller in weight than the permanent magnet. The drive circuit controls a stator current supplied to the stator windings.

    Abstract: Temperature conditioning unit (100X) includes first intake and exhaust device (10A), second intake and exhaust device (20A), and housing (30) that accommodates element (50) to temperature-condition. First intake and exhaust device (10A) and second intake and exhaust device (20A) each include: a rotary drive device including a shaft and a rotary drive source that rotates the shaft; an impeller including an impeller disk that engages the shaft at its central part and includes a surface extending in a direction intersecting the shaft, and a plurality of rotor vanes erected on the impeller disk; and a fan case including a side wall surrounding the impeller, an intake port, and a vent communicating with an interior of housing (30). The plurality of rotor vanes each extend in a direction from the central part to an outer peripheral part of the impeller disk in the shape of a circular arc bulging in a rotation direction of the shaft. A frequency at which first intake and exhaust device (10A) produces a sound having an energy peak is different from a frequency at which second intake and exhaust device (20A) produces a sound having an energy peak.

    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: 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 permanent-magnet-embedded electric motor includes a stator having a coil wound on a stator core, and a rotor disposed rotatably inside the stator through a gap to an inner circumferential surface of the stator core. The rotor is provided with a rotor core formed of laminated steel plates having a plurality of magnet-embedding holes, and a permanent magnet housed and retained in each of the magnet-embedding holes. A thickness of the bridge portions formed between edges of the magnet-embedding holes and an outer circumference of the rotor core, and a thickness of a thinned link portion connecting adjoining two of the bridge portions are thinner than a thickness of the steel plates.
