摘要： In a motor control device, a communication interface receives a control command defining a target rotation amount and a target rotation speed of a motor. A sensor interface receives a detection signal from a rotation angle sensor outputting a detection signal in every rotation of the motor at a predetermined angle. A controller decides a set value of a rotation speed of the motor. A drive signal generator generates and outputs a drive signal for rotating the motor. The controller calculates a difference between the target rotation amount and a total rotation amount of the motor from start of execution of the control command, based on the number of received detection signals, and determines whether an abnormality occurs in operation of the motor based on an update frequency of a minimum value of the difference or a non-update period when the minimum value of the difference is not updated.

摘要： A motor control system and method are provided for detecting current ripple in a commutated DC motor and further determining position and speed of the motor based on the detected ripple current. Ripples in the motor current are detected and a ripple frequency is calculated based on the time between successive ripples. A ripple count between successive frequencies is determined and the ripple count is compared to a threshold value, and an estimated ripple frequency is determined from a motor model when the ripple count exceeds the threshold value. A corrected ripple count is calculated from a ratio of the calculated ripple frequency and the estimated ripple frequency, and motor position and motor speed are determined based on the corrected ripple count.

摘要： A method for determining the rotational position of the drive shaft of a DC motor includes providing a period of a reference current ripple indicative of proper operation of the motor. The period of the reference current ripple is then compared with the period of each current ripple contained in a rotor current signal of the motor during operation of the motor. The current ripples of the rotor current signal of the motor having periods which differ from the period of the reference current ripple are then corrected. A corrected rotor current signal based on the corrected current ripples and uncorrected current ripples of the rotor current signal of the motor is then generated. The current ripples contained in the corrected rotor current signal are then counted to determine the position of the drive shaft of the motor and, consequently, the position of an element being driven by the motor.

摘要： A method for determining the rotational position of a motor drive shaft includes counting detected ripples contained in a motor current signal as the shaft is driven. Whether a ripple expected to be contained in the current signal at a probable time is absent from within a tolerance band containing the probable time of the expected current ripple is determined. If the expected ripple is absent from within the tolerance band containing the probable time, then whether a ripple is detected after the tolerance band of the expected ripple is determined. If a ripple is detected after the tolerance band and the expected ripple is absent from within the tolerance band, then the expected ripple is counted as a detected ripple. The determined rotational position of the shaft is based on the counted ripples. The length of the tolerance band dynamically changes as a function of a motor operating state.

摘要： A method for calibrating electric motors using current-sensing only is disclosed. The method involves applying a voltage in pulse-width modulated fashion for a short time to insure motion of the motor. Following startup, varying voltages are pulsed to the motor, switching polarity at regular intervals. The current generated in the motor by each level of voltage is measured. The data generated provide a reasonably accurate view of the properties of the motor, allowing for more precise velocity control.
