Abstract: 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.

Abstract: A method for determining the position of a movable element driven by a motor shaft includes using a counter to count current ripples contained in an armature current signal of the motor as the motor shaft rotates to drive the element. The position of the element is determined based on the counted current ripples. Upon power to the motor being interrupted such that the motor shaft slows down during the power interruption and upon the counter being prevented from counting the current ripples contained in the armature current signal of the motor during the slowdown of the motor shaft, an amount of current ripples expected to be contained in the armature current signal of the motor during the slowdown of the motor shaft is estimated. The position of the element during the slowdown of the motor shaft is determined based on the estimated amount of current ripples.

Abstract: The invention relates to a method for detecting the rotational position of the drive shaft of a DC motor and especially the position of an element driven by the drive shaft within a predetermined path of movement by evaluating the current ripples contained in the rotor current signal. The inventive method is characterized in that a period of a reference current ripple is provided during operation of the DC motor. The period of the reference current ripple is compared with the period of every current ripple detected during operation of the DC motor. If there is not sufficient agreement of the periods between the period of the reference current ripple and that of a detected current ripple, the periods of the current ripple signals that are not sufficiently in agreement are corrected with respect to the period of the reference current ripple.
