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： In a power-transmission control mechanism for controlling transmission of power from an internal combustion engine of a lawn mower to mowing blades, a controller for an electromagnetic clutch periodically repeats: reading detected engine rotational speed during a predetermined time, when an operating switch is turned on; comparing present engine rotational speed read in the present cycle with previous engine rotational speed read in the previous cycle; engaging the electromagnetic clutch when the present engine rotational speed is equal to or higher than the previous engine rotational speed; and disengaging the electromagnetic clutch when the present engine rotational speed N is lower than the previous engine rotational speed. Thus, the power of the engine is reliably transmitted to the mowing blades without occurrence of engine stall and without being influenced by the load following characteristic of the engine, the clutch, and load fluctuation.

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.

摘要： A working machine having a working part driven by an engine and a transporting part driven by an electric motor. The rotation of the electric motor is controlled by a control part. The speed of the engine as of when the working part is brought to a working state by a work on/off switch being turned on is taken as a reference speed, and a correction coefficient corresponding to this reference speed is taken as an upper limit value. A correction coefficient corresponding to the present speed of the engine is determined. A required acceleration set in correspondence with the size of the actual travel speed of the transporting part is multiplied by the determined correction coefficient to correct this required acceleration. The control part acceleration controls the rotation of the electric motor in accordance with the corrected required acceleration.

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.
