摘要： The invention is a low-cost stepper motor drive system comprising a microstepping motor and a logic circuit. The logic circuit includes two integrated circuits for controlling one or more phases of the microstepping motor. Each one of the integrated circuits is a motor driver capable of producing up to sixteen microsteps per full step. Further, each one of the integrated circuits takes a set of analog/digital bits and a phase bit as input. Additionally, within the logic circuit, there is included a microcontroller for controlling the microstepping motor. The microcontroller comprises six control bits, which direct the controller in outputting a set of step sequences to the integrated circuits. The microcontroller can run in one of two program modes: a stand-alone mode which utilizes two profile bits to select one of a set of four slew velocities and which will accelerate the microstepping motor then slew at a preprogrammed velocity as selected by the two profile bits; and, a pulse controlled mode, wherein the motor velocity of the microstepping motor is directly related to an input pulse signal wherein each time the microcontroller receives the input pulse signal the microcontroller will output a step to the integrated circuits. The logic circuit further includes a driver circuit for driving current through each one of the motor phases, and two snubber circuits operatively located between the outputs of each one of the motor phases of each integrated circuit for stabilizing the voltage level of the logic circuit.

摘要： A drive unit for calibrating an indicator/meter of a vehicle is provided in which a pointer in an indicator for a vehicle can point immediately after an ignition switch is turned ON, and the frequency of seeing motion of the pointer in an initializing operation by a car driver is reduced. A sensing mechanism (8a-3) is provided to sense an open/close operation of a door. Correspondingly to the sensing of the sensing mechanism (8a-3), a drive-start mechanism (8a-4) starts rotation of a stepping motor using a drive mechanism (8a-1) for initialization. The drive mechanism (8a-1) during initialization rotates the stepping motor to move a driven member toward a stopper.

摘要： A printing apparatus includes a stepper motor automated self-test routine that gives an approximation of the state of the degradation of the stepper motor and/or its driven load. The test includes artificially increasing the starting frequency above normal and/or reducing the operation current below normal by a known and controllable amount to the stepper motor and tracking the level at which the motor is just able to start operating. By examining the magnitude and/or change in these levels, the remaining life and reliability of the motor can be predicted. Alternatively, the self-test routine could be used in conjunction with paper path sensors to determine the start time for a stepper motor. The start times are stored for trend analysis.

摘要： A method and apparatus for automatically detecting an occlusion or drive system failure in a medication infusion system is provided. The electrical current to an infusion pump is measured and compared against a baseline average current. If the current exceeds a threshold amount, an alarm is triggered. Alternatively, pump motor encoder pulses are measured during a pump cycle. If the number of pulses do not correspond within a normal range, an alarm is triggered. After any alarm is triggered, the pump motor is driven in reverse for an incremental distance in order to relieve the fluid pressure in the system.

摘要： A method for controlling a step motor of a scanner by using three sets of parameters is provided. The three sets of parameters include a pulse count number PCN, a count base CB, and a motor constant speed interval MCSI. The method includes the follow steps. First, generate a synchronous trigger signal in correspondence with each exposure trigger signal CVTR generated by an image sensing module of the scanner and clear a base accumulator BA. Then, add the count base CB to the base accumulator in correspondence with each reference pulse. Finally, generate an asynchronous trigger signal and clear the base accumulator when the base accumulator is greater than or equal to the pulse count number PCN. Since the speed of the step motor only relates to the pulse count number PCN and the count base CB, the step motor can be controlled by only setting these parameters.
摘要翻译：提供了一种通过使用三组参数来控制扫描仪的步进电机的方法。三组参数包括脉冲计数PCN，计数基CB和马达恒速间隔MCSI。该方法包括以下步骤。首先，产生与由扫描仪的图像感测模块产生的每个曝光触发信号CVTR相对应的同步触发信号，并清除基本累加器BA。然后，将每个参考脉冲对应的计数基CB加到基本累加器。最后，当基本累加器大于或等于脉冲计数PCN时，产生异步触发信号并清除基本累加器。由于步进电机的速度仅与脉冲数PCN和计数基CB相关，所以步进电机只能通过设置这些参数进行控制。

摘要： A step-motor-driving device includes (a) a step-motor having driving-windings in plurality of phases, (b) an exciter for supplying power to excite driving-windings, (c) a position detector for detecting a position of a mover of the motor and outputs a position-detecting-signal, and (d) an excitation-timing-controller for receiving a driving-instruction-signal and a position-detecting-signal, and outputs an exciting signal to the exciter responsive to an input of one of the driving-instruction-signal and the position-detecting-signal. The excitation-timing-controller outputs the exciting signal responding an input of the driving-instruction-signal when an excitation-switch of the driving-winding responsive to the driving-instruction-signal directs torque in a direction effective for the motor to rotate in a desirable direction, and the controller outputs the exciting signal responding an input of the position-detecting-signal when the excitation-switch of the driving-winding responsive to the driving-instruction-signal directs torque in an unfavorable direction for the motor to rotate in the desirable direction. This structure allows the step-motor-driving device to be free from jumping “out of sync”.

摘要： An abnormality detector for motor drive system easily detects, using a CPU, abnormality such as short circuit or disconnection in magnetic field coils of a motor, wiring, an open/close element, etc., which are controlled by a microprocessor (CPU). The open/close elements conducting an open/close operation sequentially in response to pulse outputs P1, P2 generated by the CPU, drive the magnetic field coils. Surge voltages generated upon interrupting the mentioned open/close elements are OR connected through a diode, and input to a temporary storage circuit. Then the CPU reads out, stores and resets the surge voltages using pulse edges of the pulse output P1 or P2. When any generation of the surge voltage is not stored in the temporary storage circuit, the CPU operates an abnormality alarm display.
