摘要： According to an embodiment, radially extending inner spacers are provided in a stator core at a distance from each other in the circumferential direction at intervals between a prescribed number of stacked magnetic steel plates, and ventilation ducts for cooling gas flow are formed in the radial direction. The perimeter of each ventilation duct is defined by the inner spacers and a magnetic steel plate separated by the inner spacers. The cooling gas, which flows in the rotation direction, is split laterally to both sides of a rotor coil and directed toward the outer circumference. Portions of the shoulder parts of a wedge are cut off such that the width of the shoulder parts of the wedge at positions corresponding to the ventilation ducts matches the slot width.

摘要： A wireless communication device capable of restraining dispersion of a propagation environment index and thereby improving throughput. A reception controller receives a pilot signal, measures a propagation environment and detects a phase change of the pilot signal. A moving average processor obtains a moving average of propagation environment values. An index function setter generates a propagation environment index function indicative of the correspondence between the propagation environment value and a propagation environment index which is a propagation environment quality index. When the detected phase change is greater than a threshold, a slope corrector corrects the slope of the propagation environment index function by using the moving average as a reference point, and a propagation environment index transmitter obtains a propagation environment index corresponding to the measured propagation environment value by using the propagation environment index function whose slope has been corrected, and transmits the obtained index to a base station.
