    摘要: A chopper control system for controlling the amount of power supplied from a DC power source to a load having inductance. The chopper control system comprises a chopper circuit for accomplishing the on-off control of main current flowing from a DC power source to a load having inductance, and a duty cycle control circuit for controlling the duty cycle of the chopper circuit. A flywheel circuit including a series-connected circuit of a flywheel diode and a reactor is connected in inverse parallel with the load. The counter electromotive force induced in the flywheel circuit is detected by a detecting circuit and the output of the detecting circuit is applied to the duty cycle control circuit to prevent the main current from exceeding a predetermined value.

    摘要: A slip ring is made of a carbonaceous material and a brush is made of a metal. A metal connection bar has an insert member held in the carbonaceous slip ring to make a mechanical and electrical connection without the necessity of an additional member. The slip ring and the connection bar are insert-molded in a slip-ring-support made of a resinous material. The slip-ring-support is press-fitted to a rear portion of the rotor so that the slip ring and the connection bar are fixed to the shaft at the same time. Further, the fan unit having a plurality of fan blades and a fan-supporting-portion is molded integrally with the slip-ring-support.

    摘要: A vehicular generator motor performing generator operation and motor operation is disclosed. The generator motor comprises an AC-DC converter means and a switching means. The converter means is composed of a plurality of MOSFETs and connected between each armature coil and a vehicular storage battery. Alternating current produced across the coils is converted into a direct current for charging the battery by the AC-DC converter means in generator operation mode. In motor operation mode, the DC output from the battery is converted into an alternating current for setting up a rotating magnetic field by the converter means, and the battery output is fed to the armature coils. The mode of operation of the MOSFETs is switched between these two modes by the switching means. The rotating field produces a certain phase difference with the magnetic field developed by the rotating magnetic poles. The MOSFETs are made of SiC having a smaller resistivity than that of Si. This ensures a high withstand voltage necessary during power generation. Loss caused by large current flowing in the motor operation mode is reduced. Good driving torque can be obtained.

    摘要: An electric power generating device including an induction type electric rotating machine rotating in interlock with an engine comprises an inverter connected at the AC side to and end of an armature winding and at the DC side to an electric power storing device, a detecting means for detecting the quantity of state related to the electric power generating voltage of the induction type electric rotating machine excluding the measured RPM of the induction type electric rotating machine but including the electric power storing voltage of the electric power storing device, and an electric power generation controlling means for maintaining the electric power storing voltage within the preset range by controlling the frequency of the controlling voltage of the inverter based on the quantity of state related to the electric power generating voltage. This electric power generating device can control the electric power generation without using any RPM detecting device for the induction electric machine, and as a result, the composition of the device can be simplified. The frequency can be controlled so that the frequency can be changed in the direction in which the difference between the electric power storing voltage and the preset reference voltage is reduced.
