Abstract: A unit of absolute rotary position encoding, where the angular range of encoding is matched to the number of poles of an electrical motor it is intended that the encoder is to be attached to. The electrical motor is suitably a brushless DC motor. This provides unique rotational position values only through an angle corresponding to an angle between two consecutive poles to enable control/drive electronics to accurately and smoothly turn the rotor from standstill and at low speeds with varying loads applied to the motor.

Abstract: In order to cope with many rotor diameters using a single type of stator portion, two stator portions, each having a built-in signal processing circuit for detecting absolute positions independently, are disposed in opposition at positions which differ from each other with respect to a rotational center of a rotor portion. When one of the stator portions receives a request command RX from an external device, it transmits a detected serial communication signal. The other stator portion receives the transmitted serial communication signal, determines a position detection abnormality, and notifies the abnormality to the external device when a difference between the received absolute position and the absolute position detected by the other stator portion exceeds a deviation previously set for 180 degrees.

Abstract: A method for determining the absolute value of a rotational angle includes imaging a continuous segment of a code track of a code carrier on a sensor array such that the sensor array generates a corresponding output signal. The code track includes a code provided over an angular range of 360°. The code contains a plurality of code words with each code word respectively corresponding to an angular value in the angular range. The output signal is correlated with a reference signal in a correlation filter to produce a correlation function signal. The reference signal is indicative of the code and the angular values corresponding to the code words. The correlation function signal is processed to determine the code word of the imaged segment of the code track as a function of the angular value where the output signal best coincides with the reference signal.
