Abstract: The present invention aims to provide a dynamo-electric machine allowing high-voltage resistance, high-heat resistance, and stress resistance to improve. The object can be attained by providing a dynamo-electric machine having a stator or a rotor including a wound coil, a slot core containing the wound coil, a first insulant arranged around the wound coil and mainly formed of an inorganic material, and a second insulant arranged between the inorganic insulant and the slot core and mainly formed of an organic material.

Abstract: The present invention provides an inter-bus-bar built-in capacitor capable of reducing the size of a capacitor used in an inverter or the like or downsizing the capacitor, and provides power equipment as well as a power converting apparatus. The inter-bus-bar built-in capacitor is provided between a pair of opposing bus bars and includes a high-dielectric-constant material which has a relative dielectric constant of at least 50 when a voltage of 1,000 V is applied at a temperature of 25° C. Thus, it is possible to provide the inter-bus-bar built-in capacitor capable of reducing the size of a capacitor used in an inverter or the like or downsizing the capacitor and provide the power equipment as well as the power converting apparatus.

Abstract: An electrical rotary machine includes coils including element wires wound, and a core holding the coil, wherein spaces, both between the coils and the core, and between the adjacent element wires, are filled with a heat-conductive insulating resin. A method of manufacturing the electrical rotary machine includes a first step of impregnating the coils and filling the space between the adjacent element wires with the heat-conductive insulating resin, and a second step of impregnating the coils and the core and filling the space between the coils and the core with the heat-conductive insulating resin.
