Abstract
In the working machine wherein the output of an engine generator is directly supplied to a motor for travel without using the intermediary of a battery, preventing the engine from slowing down. The generator G is directly connected to the motorand there is no battery that stores the output of the generator G. CPUdecreases the power supply for the motorwhen it has been anticipated that the engine revolutions will be decreased. The number of the engine revolutions is detected according to the period of the waveform of an output of the generator G. The alternating current waveform that has been drawn out from one phase of the winding of the generator G is shaped into a rectangular waveform. CPUdetects the period of the shaped waveform. When the detected period has become larger, the CPUdetermines that the engine revolutions is about to decrease.
