    摘要: A motor driving apparatus for driving and braking a motor equipped with a brake comprises a motor/brake driving DC power supply which is used both as a motor driving power supply and as a brake driving power supply, wherein when the motor/brake driving DC power supply is being used as the motor driving power supply, a voltage conversion circuit via which a voltage supplied from the motor/brake driving DC power supply is applied to the brake feedback-controls the voltage applied to the brake. This configuration serves to reduce the loss (due to temperature rise) in the brake coil of the motor being driven to move a robot arm.

    摘要: An arc welding method using a welding material having a low transformation temperature, characterized in that it is carried out by the use of a shielding gas consisting of a rare gas alone or a mixed gas of a rare gas and a small amount of an oxygen gas; and an additional welding method using a welding material having a low transformation temperature, characterized in that it is carried out while moving a weld line in the form of a straight line. The former method allows the enhancement of a Charpy value in combination with improved fatigue strength, and the latter allows the experience of heat history of the material having a low transformation temperature to be suppressed, resulting in the prevention of weld crack in combination with an improved fatigue strength.

    摘要: Provided to the motor controller is means which can alter a conversion ratio with which a current value detected by a current detector is converted into a unit (such as voltage) easily usable in motor current control. According to the maximum current value of the motor and the demagnetization limit current of the motor, an optimum conversion ratio is selected and switched over. By making it possible to select and preset a conversion ratio, a plurality of motors can be controlled by one motor controller. Therefore, restrictions imposed on the combination of the motor controller and the motor are lightened.

    摘要: A bridge-type main valve located at a connecting outlet between a vacuum chamber and a main vacuum pump, and having a rod of an electric cylinder driven by a stepper motor connected to a valve seat for opening and dosing the connecting outlet so that the driving direction and a closing surface of the valve seat form a right angle. A piston may be attached to the rod, and a cylindrical housing fitted in the piston so that the piston and the cylindrical housing form a pressurized air pumping chamber for moving the rod and the valve seat in the outlet closing direction. The valve can achieve fine pressure adjustment without any variable orifice by stopping a valve seat at an arbitrary (not stepwise) position.
