  • Publication number: 20170220091
    Abstract: The present invention provides a power-supply management device which can efficiently connect and disconnect power supply to an electric-powered section, and a machine tool including the power-supply management device. The power-supply management device (101) detects a synchronization command of a control program, and compares an operation time of the electric-powered section between synchronizations in each control system which is a synchronization target by the synchronization command on the basis of the detected synchronization command. Then, the power-supply management device (101) disconnects the power supply to the electric-powered section belonging to the control system except the control system having the maximum operation time of the electric-powered section between the synchronizations, and restarts the power supply at the end of the synchronization in each control system.

  • Patent number: 6917121
    Abstract: A power generator unit incorporates an engine and a generator driven by the engine. The generator incorporates a multi piece sound insulation cover that allows for efficient cooling of the various internal components. A plurality of cooling paths are created within the cover and air is drawn into and through the cover by two separate fans. An engine cooling fan draws in cooling air through a generally dedicated cooling air vent(s) to cool an electronic control(unit, an engine cylinder, and a muffler. A generator cooling fan draws in cooling air through an additional cooling air vent(s) to cool an engine crankcase and the generator. The insulation cover provides quiet operation and efficient cooling of the power generator.
