The canned electric motor includes a static motor frame, a rotor shaft, a rotatable motor rotor which is co-rotatably connected with the rotor shaft, a static motor stator having a stator body which is directly fixed to the static motor frame, and a separating can which fluidically separates the static motor stator from the rotatable motor rotor. The separating can has a first axial support which protrudes radially from an outside of the separating can. The separating can is supported in a first axial direction by the stator body via the first axial support and in a second axial direction by the static motor frame. The first axial direction is opposite to the second axial direction.

Abstract: An electronically commutated electric motor includes a stator with stator coil(s), a magnetized rotor which rotates relative to the stator, the magnetized rotor having at least two opposite magnet poles which generate an excitation field, a static magnetic field sensor which detects the excitation field and generates a sensor signal having signal edges, a full-wave signal period, and half-wave lengths of an N- and an S-signal level, a motor energizing device which drives the stator coil(s) and generates a revolving stator field when triggered by a trigger signal, a memory unit which saves parameter values, and an evaluation unit which generates the trigger signal via a shift compensation of an asymmetric shift of the signal edges of the sensor signal. The shift compensation is calculated based on a position of a received sensor signal edge, the full-wave signal period, and the half-wave lengths of the sensor signal.
