    摘要: A generating apparatus includes a generator, a first and a second rectifiers, and a voltage regulator. The generator has three-phase star-connected armature windings which generate three-phase high-output voltage at phase-terminals and low-output voltage at a neutral point. The first rectifier is a three-phase full-wave rectifier connected between the phase-winding and a high-voltage load, and the second rectifier is a diode connected between the neutral point and a low-voltage load with a battery. The regulator regulates the high output voltage to energize the high-voltage load and, at the same time, the low-output voltage to become an optimum voltage level for charging battery. MOSFETs may be used for the first rectifier to short-circuit the armature windings thereby supplying them with leading currents which are respectively ahead of the high-output voltages, so as to increase the generator output power.

    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.

    摘要: An alternating current generator for a motor vehicle includes magnet type field cores, i.e., field cores with claw poles on which permanent magnets are interposed in the spaces between the claw poles, where the generator has a ratio of number of claw poles/outside diameter of the field core that allows generation of a large output current. The alternating current generator includes permanent magnets disposed in spaces between peripherally adjacent claws which reduce the magnetic flux leakage caused by the field coil occurring in the spaces. When a residual magnetic flux density higher than 0.25 tesla is applied in advance in a direction that reduces magnetic flux, a large output current is obtained when the above-noted ratio is in the range of from about 1.6.times.10.sup.-1 to 2.0.times.10.sup.-1 (1/mm).

    摘要: An automotive alternator includes a rotary shaft, a pulley, a stator, a rotor, and a magnetic fluctuation suppressor. The pulley is provided on the rotary shaft to transmit rotating power from an engine to the rotary shaft. The stator includes a stator winding. The rotor is mounted on the rotary shaft and configured to provide a first rotating magnetic field to the stator. The magnetic fluctuation suppressor includes a magnetic body and a magnetic source. The magnetic body is mounted on the rotary shaft such that the magnetic body is rotatable along with the rotary shaft at a rotational speed different from that of the rotary shaft. The magnetic source is fixed to the rotary shaft so as to create a second rotating magnetic field which induces a magnetic attraction between the magnetic body and the magnetic source, by which fluctuations in rotational movement of the rotary shaft are suppressed.

    摘要: A method of calculating torque of a Lundell-type synchronous generator is disclosed in which only power generation output current and a rotational speed are input for calculation of the amount of electric power and the amount of losses for thereby enabling calculation of power generating torque, based on a sum of the amount of electric power and the amount of losses, which is generated as an output. The present method establishes formulae enabling calculation based on only output current and the rotational speed, enabling a minimal number of inputs to shorten a calculation time interval.

    摘要: A print head driving circuit is provided whereby, even if the load changes, the accuracy of the driving voltage waveform supplied to the load can be maintained, and consequently, deterioration in printing quality can be prevented. Transistors Q3, Q4 connected in a push-pull configuration are connected to the upstream of a transistor Q1. If the base potential of the transistor Q1 rises above its normal level, then the emitter potential of the transistors Q3, Q4 will rise and the transistor Q3 will become non-conductive, and the transistor Q1 will also become non-conductive, but since the transistor Q4 is conductive, the current I2 will flow from the base terminal of the transistor Q1, to earth, via the transistor Q4, and hence the base potential of the transistor Q1 will fall to or below the prescribed value. As a result, it is possible to prevent the base potential of the transistor Q1 from rising up in excess of the prescribed value.
