    摘要： An control system for an induction motor driven by an AC output of variable frequency and voltage produced from an inverter which converts DC power obtained by a converter through conversion of AC power having constant voltage and constant frequency. The system comprises means for estimating the power factor of the induction motor from an input current to the inverter, means for controlling the voltage of the AC output from the inverter when the estimated power factor is outside a predetermined range, and means for restricting the control of the AC output voltage to prevent the ratio between the AC output voltage and the AC output frequency from exceeding a predetermined range.

    摘要： A power module can prevent damages due to cracking or breakage of an insulating substrate when molding even if a heat plate constituting a power module pre-product is made areally smaller than the insulating substrate, and can also sufficiently satisfy demand for minimization. Specifically, the power module pre-product is sealed by a molding resin layer in a state where externally exposed end portion on one end side in both external connecting terminals and the other surface side of a heat plate are each exposed to the outside. The power module substrate constituting a multilayer substrate body includes an aligning hole, into which an aligning pin is inserted, the pin being included in a lower molding die constituting a molding die with an upper molding die that molds a molding resin layer, so as to position the power module pre-product inside a cavity.

    摘要： A manufacturing method of a hybrid permanent magnet type electric rotating machine including a stator that is constructed by winding excitation coils around respective main poles. A rotor is constructed by fixing a first rotor unit, which consists of a pair of rotor cores and a magnetic material sandwiched between the rotor cores, and a second rotor unit, which has the same construction as the first rotor unit, to a rotation shaft. The rotor is assembled to the stator to form an assembled body. The magnet material of the first rotor unit is magnetized in the axial direction by a magnetizing flux passing through a half of the assembled body in the axial direction. The magnet material of the second rotor unit is magnetized in the axial direction in an opposite polarity by a magnetizing flux passing through the remaining half of the assembled body in the axial direction.

    摘要： A stepping motor includes: a stator having main magnetic poles each having small stator teeth on its tip, a core-back portion that connects outer portions of the poles, and windings wound around the poles; and two sets of rotor units that are arranged in an axial direction and face the stator with an air gap therebetween. Each rotor unit consists of two rotor cores that are separated in the axial direction and a magnet sandwiched thereby and magnetized in the axial direction. Each rotor core has small rotor teeth around its outer surface. The rotor cores of each rotor unit are deviated by ½ pitch of the small rotor teeth, and the two rotor units are arranged to make the magnetic polarities of the small rotor teeth of the adjacent two rotor cores identical. A magnet thickness Tm and a rotor core thickness Tc satisfy 0.25≦Tm/Tc≦0.45.

For applications to a high power supply, the system comprises a plurality of variable power converters adapted to operate selectively in accordance with requisite power information sources provided in or on the side of a plurality of loads, thereby providing a system realizing a flexible power supply. For application to a low power supply, the system comprises a plug having a power specification information source and a socket having a variable power converter.
