Abstract (en)
[origin: WO2017182191A1] The invention relates to a brushless DC motor (1) as an external rotor with an analysis and control unit (7), a stator, a rotor, a co-rotating bell (5), and a sensor (10) which detects an angular position of the rotor. The invention also relates to a method for providing an angle signal. A target (20) with at least one electrically conductive track (22) is attached to the co-rotating bell (5), and the sensor (10) is designed as an eddy current sensor with at least one coil. The sensor (10) is arranged at a radial distance from the target (20) such that the at least one electrically conductive track (22) at least partly covers the at least one coil. The sensor (10) provides an angle signal as a function of the at least one coil being covered by the at least one electrically conductive track (22), said angle signal uniquely representing the absolute angular position of the rotor up to 360°.
