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： Even when a cheap magnetic responsive element is used for a magnetic detecting portion, a rotation detector excellent in vibration resistance is provided, a housing 1 being provided with a tubular insertion portion 1a through which an axle 13 is inserted. A rotor 5 is provided with a cylindrical portion 5a through which the insertion portion 1a is inserted and that has a plurality of magnetic poles and rotates synchronously with a front wheel (wheel) 11 fitted to the axle 13. The magnetic detecting portion (rotation detecting portion) 3 detects a change of magnetic poles accompanying the rotation of the cylindrical portion 5a. A spacer (magnetic member) 4 is disposed in the surroundings of the insertion portion 1a of a bottom portion 1g of the housing 1, and holds the rotor 5 at the bottom portion 1g when the cylindrical portion 5a is fitted into the insertion portion 1a.

摘要： In an evaluation circuit for evaluating an output signal of a magnetoresistive sensor (1) for rotational speed measurement, in which the evaluation circuit performs an offset compensation of the sensor signal and comprises a comparator (4) which receives the offset compensated sensor signal and compares it with a reference voltage, a reliable identification of the output signal of the sensor after switching on the arrangement is ensured in that, in an initial mode, the value of the reference voltage is selected in dependence upon the temperature, the temperature dependence being approximated to that of the sensor signal, in that a control unit (6) is provided which, in the initial mode, consecutively checks whether the sensor signal is present, triggers the offset compensation only after the presence of said signal, subsequently checks whether the comparator (4) supplies an output signal, and changes over to a control mode only after the presence of said signal, in which control mode the temperature dependence of the reference voltage is switched off and, instead, the reference voltage is adjusted to approximately 40% of the maximum amplitude of the offset-compensated sensor signal.

摘要： An improved method, for obtaining a datum concerning the rotation speed (n) of a rotating object, such as a motor rotor (32), offers high precision. Typically, the motor has a sensor (61) which supplies a sensor signal that has, for each revolution of the rotor, a plurality A of events such as pulses or pulse edges which are counted by a microprocessor (23) associated with the motor. In order to keep the computation load on the microprocessor from increasing as the rotor speed increases, yet maintain high precision, the measurement is done over a full rotation of the rotor, starts at a first signal event (176), and ends after a third or nth signal event (182) which happens at the same rotational position as the first signal event.

摘要： Through differentiation of input signal Vw from a sensor the angular frequency &ohgr; becomes included in the amplitude component. Through a plurality of differential operations the amplitude including the angular frequency &ohgr; varies, but the time-dependent term becomes equal. Since the amplitude of the signal Vw outputted from the revolution speed sensor 10 is approximately constant, the angular frequency &ohgr; proportional to the revolution speed can be extracted by determining a ratio thereof.
