Abstract: A stepping motor controller for controlling a stepping motor, includes: a motor driver; and a driver control unit. The motor driver includes: an excitation phase control unit; and a drive unit. The driver control unit includes: a motor driver power control unit; a drive control unit; a clock signal output unit; and an excitation phase storing unit. The excitation phase storing unit acquires an excitation phase at a time when the motor driver power control unit stops supplying electricity to the motor driver, and stores the acquired excitation phase as a suspension excitation phase.

Abstract: A meter system includes: an indicator including a pointer, a step motor, a stopper mechanism and a driving controller; and a flasher function unit including a flasher switch, a flasher and a flasher controller. The driving controller has: a stopper position detection operation executing element for executing a pointer moving away operation when a stopper position detection operation executing condition is satisfied and for executing a voltage detection type zero point stopper position detection operation when the executing condition is satisfied, and the flasher switch does not turn on and off, and a zero point return enforcement type zero point stopper position detection operation when the executing condition is satisfied, and the flasher switch turns on and off; a zero point setting element; and an applying element for applying the driving signal having the zero point.

Abstract: A motor drive and a method in connection with a motor drive including a frequency converter are provided. The motor of the drive is connected to a load, and the motor is controlled with the frequency controller. The method includes the steps of converting changes in electrical quantities of the motor caused by actions affecting the load into observations representing the changes, selecting control symbols on the basis of matching of the sequences of observations with a set of valid patterns, and controlling the converter based on the selected symbols.

Abstract: Motion control using electromagnetic forces. The control of motion in unpowered apparatus and an apparatus driven by electric motors and/or other prime movers utilizes electromagnetic force/torque for control of motion. One objective is to extend the domain of electric motor speed control, traditionally characterized by electronic techniques, to small apparatus such as bubble vibration toys, paper dispensers, toothbrushes and other appliances.

Abstract: A method of varying speed and direction of motor operating intervals in a food processing device to achieve real time load adaptation comprising a motor (512), control circuit (501), motor drive circuit (511), and voltage and current sense circuits (510) to control said motor based on ingredient and desired function input from a user input device (509) and known motor and ingredient load profile data stored in non-volatile memory (504). An analog to digital converter (502) is used to read motor load data using voltage and current sense circuits (510) to index said motor and ingredient load profile data enabling said control circuit (501) to alter speed and direction of motor (512) operation to provide consistency in results of final mixture irregardless of variations of initial ingredient quantity and viscosity.

The present invention also relates to a method for controlling a windshield-wiper motor and a windshield-wiper motor having a contact-disk system according to the present invention.

Abstract: It is an object to obtain a press apparatus and a press controlling method which apply press working to a processed object with accurate press load and is capable of press working with accurate press load without affected by variations in thickness of the processed objects and variations in shut height of molds. A servo motor (51) is connected concentrically to a rotation transmitter (52), and a screw shaft (53) is provided passing through the center of the rotation transmitter (52). The driving force of the servo motor (51) is converted into a thrusting force of a press ram (54) by combining the rotation transmitter (52) and the screw shaft (53). Correct press load is applied to the processed objects and troubles in the press processing caused by variations in thickness of the processed objects can be prevented.

Abstract: When a sewing machine is locked during stitching of a thick fabric, the rotational direction of a sewing motor is alternately reversed at a predetermined time interval. A needle operatively coupled to the sewing motor through a mechanical system is moved up and down, whereby the needle sticks into the same stitching point for a desired number of times.

Abstract: A pump speed control for filling machines in which the rotational speed of the pump is varied between its intake stroke and the discharge stroke by selectively controlling the speed of the driving motor as a function of the rotational position of the output shaft of the driving motor.
