EXTERNAL ROTOR MOTOR WITH A VARYING ARMATURE PROFILE

摘要

The invention relates to an external rotor of an electric machine and to a production method for an external rotor of this type. To achieve the lightest possible construction, the external rotor has an armature thickness that is defined in the direction of the external rotor radius and that varies in the circumferential direction, said armature thickness having a first value (1) beneath the poles (3) of the external rotor and a second value (2), which differs from the first, in the pole gaps (4) between the poles (3).
