    摘要： A control device for an electric generator for use with a vehicle engine includes an armature winding (stator) and a field winding (rotor) driven by the vehicle engine. A chopper is provided for controlling the field current of the field winding and a pulse width modulator is provided for controlling the duty cycle of the chopper in response to the operating conditions of the engine. A voltage feedback loop is provided from a normally provided battery which loop incorporates a detector for detecting the actual battery voltage and a comparator for comparing the battery voltage with a predetermined set voltage so that the difference in voltage is rendered to zero. The invention additionally provides a current feedback loop for controlling a deviation between a current command value determining the duty of the chopper and an actual current flowing through the field winding so as to be substantially zero. There is also disclosed means for adaptively modifying the current command signal and means for controlling the current demanded by the field winding to reduce the torque demanded by the generator at times, inter alia, of acceleration and engine knocking.

    摘要： A controlling apparatus controls a suction performance of a blower motor which is installed into a cleaner main body. The controlling apparatus increases the suction performance when a suction nozzle is operated and decreases the suction performance when the suction nozzle is stopped. Corresponding to a floor use suction nozzle and a crevice use suction nozzle, at a predetermined air flow amount range, the most suitable operation control being suited to a discriminated suction nozzle can carried out automatically. Plural kinds of the suction nozzles at an actual use scope are set beforehand. When the suction nozzle is exchanged the flow amount range is changed over and selected with a respective suction nozzle. Plural kinds of the suction nozzles are selected and changed over automatically according to the dimension of a change amount of an operation condition. A brushless direct motor is used as the blower motor and has a domain being operated at a chopper control duty of factor 100%.
