发明名称 Electric motor, particularly an electronically commutated direct current motor
摘要 An electric motor, particularly an electronically commutated direct current motor, has a stator and a rotor. The stator and the rotor are arranged coaxially to a longitudinal axis of the electric motor. The stator features a plurality of electrical stator poles and a plurality of phase windings. The rotor features a permanent magnet with a least one magnetic pole pair which is dedicated to the phase windings. The phase windings and/or the permanent magnet are divided into several axial sections in the direction of the longitudinal axis of the electric motor and these sections are staggered around the longitudinal axis of the electric motor with respect to each other. Angular positions of the individual phases are offset with respect to each other is in such a way that torque ripple can be reduced and torque gaps can be prevented.
