EC MOTOR HAVING AN ANNULAR SENSOR MAGNET

EC MOTOR HAVING AN ANNULAR SENSOR MAGNET

In an electronically commutated motor comprising a permanently excited rotor, which has a rotor shaft (122) and which is coaxially surrounded by a stator with at least one stator winding, wherein the rotor shaft (122) defines an axis of rotation (130) of the permanently excited rotor and is rotatabl...

description In an electronically commutated motor comprising a permanently excited rotor, which has a rotor shaft (122) and which is coaxially surrounded by a stator with at least one stator winding, wherein the rotor shaft (122) defines an axis of rotation (130) of the permanently excited rotor and is rotatably mounted at at least two bearing points, which are spaced apart from one another in the longitudinal direction of the axis of rotation (130), a ring magnet (150) is arranged on the rotor shaft (122) with a magnetisation (152) which designed to be close to the surface in the region of an end side (154) of the ring magnet (150) oriented perpendicular to the axis of rotation (130), and which is designed for radially oriented and continuous detection of the rotor position by means of at least one associated magnetic field sensor (200).
