    摘要： In an inverter system including of an electric-power converter and an ac rotating machine, over-voltage generated in the ac rotating machine is controlled by a low-cost system configuration. The system includes: an electric-power converter; a three-phase ac rotating machine; and a four-core non-coaxial cable, having a ground line and three-phase electric-power supplying lines, connecting the electric-power converter to the three-phase ac rotating machine. One or two capacitors are connected between the ground line and one or two of the electric-power supplying lines, at electric-power supplying terminals on the rotating machine, so that respective capacitances between the three-phase electric-power supplying lines and the ground line are approximately equal to each other.

    摘要： An objective of the present invention is to provide a connection terminal in which the number of parts is reduced and a contact failure hardly occurs. A connection terminal is conducted to a windings wound around tooth of a stator having a cylindrical shape. The connection terminal includes an insertion part that is inserted in a concave part formed in the stator of a motor and a connection part that extends from the insertion part. In the insertion part, a contact part that comes into contact with an end part of the winding when the insertion part is inserted in the concave part, is formed. The insertion part and the connection part are integrally formed.

    摘要： A stationary induction apparatus superior in insulating ability against a surge voltage includes a coil piece on a line end side surrounded by one electrostatic shield insulating layer. The coil piece and electrostatic shield insulating layer, together with another coil piece, are surrounded by another electrostatic shield insulating layer, thus forming a successively nested configuration. Each of the electrostatic shield insulating layers includes an electrical insulating layer of pressboard and first and second conductive layers respectively located on inner and outer surface sides of the electrical insulating layer, The capacitance of each of the electrostatic shield insulating layers is adjusted to control an electrical potential distribution upon application of a surge voltage.
