FIELD: electricity.SUBSTANCE: hand-driven machine comprises an engine driven into action in the intermittent mode, a hammer coupled to the engine, a die block hit by the hammer in order to transfer rotation/hits to the operating tool, and control unit. The control unit controls rotation of the engine rotor by reswitching of the control pulse supplied to the engine depending on the load applied to the operating tool. The control pulse has the first section when the control pulse is supplied to the engine and the second section when the control pulse is not supplied to the engine. At that the control unit changes time of the control pulse delivery to the first or second section depending on the load applied to the operating tool.EFFECT: improved engine control at change of the load to the operating tool.25 cl, 34 dwg |
