摘要： Simplifying the controller of hybrid type drive unit. The output of a generator driven by engine is connected directly to a motor 7 through a converter or switching circuit 10 without being charged on any battery. The output of each phase of the generator is inputted to the converter 10. A timing controller 126 controls the conduction phase of a thyristor bridge 101 in the converter 10 so as to adjust the quantity of output power. A synchronous standard for phase control is formed based on output wave of an auxiliary winding 26 of the generator. A voltage detector 124 detects an applied voltage on the motor 7 as a motor rotation speed and the conduction angle is increased or decreased so as to maintain a detected voltage at a target value.

摘要： 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 motor 7 and there is no battery that stores the output of the generator G. CPU 102 decreases the power supply for the motor 7 when 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. CPU 102 detects the period of the shaped waveform. When the detected period has become larger, the CPU 102 determines that the engine revolutions is about to decrease.

摘要： A self-propelled working machine has a pair of transporting parts, a working part, an engine for driving at least the working part, and a main switch for turning the engine on and off. A locomotion preparation switch produces a command for moving the transporting parts when turned on and produces a stop command for stopping movement of the transporting parts when turned off. A locomotion speed setting member orders a target locomotion speed of the transporting parts. A work switch switches the working part on and off. A control part stops the engine when a first condition that the main switch is on, a second condition that the locomotion preparation switch is off, a third condition that the transporting parts have stopped moving and the target locomotion speed ordered by the locomotion speed setting member is zero, and a fourth condition that the work switch is off, are satisfied.

摘要： The invention makes an output sharing of an engine and an electric motor proper so as to suitably drive a load. When a throttle opening degree variation amount ΔV is within a ΔV1, an engine E can drive a power generator G at a rated revolution speed. A switching circuit 28 is switched in such a manner as to charge a battery 27 by a generated power. When the opening degree variation amount ΔV becomes larger than the ΔV1, a power assist of operating the power generator G as the electric motor is set to be standby. When the opening degree variation amount ΔV is more than ΔV2 (>ΔV1), the power assist is started. In the power assist, an angle advance amount is increased. When acceleration is insufficient, it is possible to further increase a conduction angle in stages.

摘要： A self-propelled work machine, in which the load of the work unit increases according to an increase in the travel speed. The self-propelled work machine includes electric motors for driving the travel units, an engine for driving the work unit, a work drive instruction unit for instructing the work unit to turn on, and a control unit for controlling the electric motors. The control unit reduces the actual speed of the electric motors by using PID control so that the actual rotational speed of the engine returns to a reference rotational speed when the actual rotational speed of the engine falls below the reference rotational speed in the state in which the work unit is turned on by the work drive instruction unit. The reference rotational speed is a reference value used when the work unit is driven by the engine.

摘要： An engine-driven generator G is concurrently used as a starter motor for an engine E that drives a working machine. A motor 25 for motive-power use is a driving source for the working machine to travel. The driving circuit 10 is commonly used between the starter motor G and the motor 25 for travel use. In a starting mode, with switches 35 and 36, the driving circuit 10 is connected to the starter motor G side to start the engine. After complete explosion of the engine, with the switches 35 and 36, the generator G is connected to a regulator 31, while the driving circuit 10 is connected to the motor 25 for travel use. As a result of this, while a battery 14 is electrically charged, the motor 25 for travel use is driven with the battery 14.
