摘要： A DC motor assembly includes a motorized unit for generating a rotatable power at an output shaft, and a step adjusting control arrangement including an optical grating and a photocoupler. The optical grating, which is operatively coupled at the output shaft, has a plurality of light transmissible portions and a plurality of light blocking portions alternating with the light transmissible portions. The photocoupler is activated to send out an impulse signal in responsive to a phase shift between the light transmissible portion and the light blocking portion of the optical grating, wherein the output shaft is controllably driven to be rotated and stopped in a sequent manner as a stepping movement thereof in responsive to the impulse signal so as to controllably adjust the rotational speed of the output shaft.

摘要： In an automatic transmission position control by a motor, it is determined whether the present instant belongs to a starting period, that is, the present instant is immediately after resetting of a control unit or application of power to it. If it is the starting period, an actual shift position that is detected from an output of an output shaft sensor for detecting a rotation position of a motor is set as an instructed shift position. With this measure, even if the control unit is reset for a certain reason while the vehicle is running, the instructed shift position is not changed in association with the resetting. This prevents trouble that the shift position is switched contrary to the intention of the driver, whereby the reliability of a position switching control can be increased.

摘要： An adjustable iri-diaphragm controller includes a brushless direct current (DC) motor, an iris defining an aperture that corresponds to an angular position of the DC motor, and a control module including a differential circuit, an integrator, and a current-limiting circuit. The differential circuit provides an output voltage corresponding to a difference between a first voltage corresponding to the angular position of the DC motor, and a second voltage corresponding to a reference aperture. The integrator provides an output signal corresponding to the output voltage. The current-limiting circuit limits supply of electric current to the DC motor in accordance with the control output signal, and inhibits the supply of the electric current to stop further rotation of the DC motor when the DC motor is rotated to an angular position corresponding to the reference aperture.

摘要： The present invention provides a control device of a position control motor for preventing step out of the position control motor, wherein the heat generated by the position control motor is small and the energy efficiency is good. The device is constituted by a detection portion 2 detecting the rotor position of a position control motor 1, first and second control portions 3 and 4 outputting signals corresponding to a current to be supplied to the motor winding based on the deviation between the position detection signal and a command position signal, first and second distribution adjusting portions 5 and 6 distributing the output signals of the first and second control portions 3 and 4, a signal synthesis portion 7 synthesizing by vector addition the output signals distributed by the first and second distribution adjusting portions 5 and 6, and an amplification portion 8 outputting the synthesized output signal to the motor winding, and the device controls the position of the motor with the command position signal. The first control portion 3 monitors the deviation between the command position and the rotor position that is detected, and based on the amount of this deviation (electrical angle), switches to one of two modes, preventing step down.

摘要： In a motor feedback control, the current supply phase is set on the basis of the encoder count of an encoder and the current supply phase is also set on the basis of the encoder count by time-synchronous processing. In the feedback control, a maximum value or a minimum value of encoder counts is stored with updating. The rotation reversing is determined by comparing the present encoder count with the maximum value or the minimum value. If reversing is detected, the reverse rotation is stopped by fixing the current supply phase. If a disconnection is detected in windings of one phase in starting a motor feedback control, one of the other two phases for which no disconnection is detected is set to the first current supply phase.
