    Abstract: PROBLEM TO BE SOLVED: To drive a stepping motor in the way fitted to its characteristics. SOLUTION: Three commands are set in a microcomputer 1; a pulse command for controlling the angle of rotation of stepping motors 8-1 and 8-2, a current command for controlling the motor current to be caused to flow in the stepping motors 8-1 and 8-2 and a rotating vector command for controlling a rotating vector generated by the motor current of each phase to be caused to flow in the stepping motors 8-1 and 8-2. Then, in each of stepping motor control circuits 2-1 and 2-2, a motor current is fed to each of the stepping motors 8-1 and 8-2 in accordance with these pulse, current and rotating vector commands.

    Abstract: PURPOSE:To supply parts more smoothly and reliably in a part supply device to supply the parts the prescribed number by the prescribed number to an external part from a stock part in which plural parts are stocked. CONSTITUTION:Since parts situated in a guide part of a sending-out means are delivered the prescribed number by the prescribed number to a carrying means 23 while locking them by a locking means 31, carrying operation of the parts held by the carrying means 23 can be effectively avoided from being hindered by the parts situated in the guide part of the sending-out means.

    Abstract: PURPOSE:To tighten a screw more easily and precisely by dividing a screw tightening process into a plurality of modes setting the rotational frequency and maximum torque is every mode and controlling the voltage of a drive motor on the basis of parameters. CONSTITUTION:In a program processing section 11, the combination of torque for tightening a screw (maximum torque) and rotational frequency is parameter set previously and a plurality of parameters are sent sequentially to a driver control section 12 according to the screw tightening condition. The driver control section 12 sets a PWM control voltage signal S3 from a difference in the rotational frequencies based on the rotational frequency specified by the inputted parameter and the rotational frequency S2 detected by an encoder 16 to send the signal S3 to a drive motor M1. Then, before and after a screw reaches a predetermine position where it is screwed in a threadingly engaging object by a predetermine amount, voltage is controlled by first and second modes having a division of controlling the rotational speed of the motor and a division of controlling constant voltage set respectively and differing from each other.
