Abstract: At a time of a heating high-load operation, a harmonic current is flown in an armature winding to induction-heat rare-earth magnets, thus reducing a residual magnetic flux density. Thereby, the number of rotations of a radial gap type motor is improved. The rare-earth magnets are provided near a cooling medium passage extending substantially in parallel with a flow line of a cooling medium, so that the cooling medium recovers heat of the heated rare-earth magnets. At a time of a cooling high-load operation, a greater number of rotations are obtained with respect to the same torque command value, by a field weakening control by means of a current-phase advance.
Abstract translation: 在加热高负荷运转时，谐振电流在电枢绕组中流向感应热稀土磁体，从而降低了剩余磁通密度。 由此，能够提高径向间隙型电动机的转数。 稀土磁体设置在基本上与冷却介质的流动线平行延伸的冷却介质通道附近，使得冷却介质回收加热的稀土类磁体的热量。 在冷却高负载运转时，通过利用电流相位前进的弱磁控制，相对于相同的转矩指令值可获得更大的转数。

Abstract: An axial gap rotary electric machine includes a rotor, an armature and a stator. The rotor is a magnetic body, which is capable of rotating in a circumferential direction about a rotation axis. The armature includes an armature coil opposed to the rotor from one side in a rotation axis direction parallel to the rotation axis. The stator causes the armature coil to interlink with a magnetic field flux from the other side in the rotation axis direction via the rotor.

Abstract: The field magnet is formed of, for example, two permanent magnets, and a width of the field magnet increases from a center toward both ends thereof in a monotonically non-decreasing manner. The field magnet includes, at the both ends thereof, projecting portions projecting to a side opposite to a rotation axis. The field core includes a penetration hole through which the field magnet is caused to penetrate. The penetration hole includes penetration surfaces which cover magnetic pole surfaces of the field magnet, respectively. Specifically, the penetration surface includes concave portions with which the projecting portions are fitted. When the field magnet is inserted, the penetration surfaces serve as a guide which guides the field magnet, and accordingly the field magnet can be caused to penetrate through the penetration hole with ease.

Abstract: A compression mechanism has a cylinder, a suction passage and a discharge passage. The suction passage of a cylinder is connected to a suction pipe. The discharge passage is open to an inner space of a sealed housing. A discharge gas is discharged through a discharge pipe. The cylinder is formed with a communicating passage extending from a suction passage to a suction pressure chamber to lead a suction gas in the suction passage into the suction pressure chamber and thereby allow a pressure of the suction gas in the suction passage to act on an outside surface of the cylinder.
