Elektronisch kommutierter Innenläufermotor

摘要

An electronically commutated motor has an external stator (28), permanent magnet rotor (36) and shaft (40) with the bearing at the drive end (52) having a small radial displacement. A nonmagnetic piece (80) presses the inner bearing ring (74) against the shaft shoulder through the action of a screw (82) An Independent claim is also included for a motor as above having a magnet to control commutation which is in a recess in the nonmagnetic piece.
