Abstract (en)
[origin: WO03049274A1] An electronically-commutated motor is disclosed, comprising an inductive and/or capacitive rotor position determination, which records a surface area in which the stator and rotor poles (10-15; 17-20) are opposite each other. The total area is taken into account for the positional determination. The pole angles ( beta S, beta R) for stator and rotor poles (10-15; 17-20) are each fixed at values which result in a change of area on a rotor rotation.
