Abstract: An electric machine may include a rotor rotatable about a motor axial direction, a stator including a laminated core with axially successive laminations, a carrier to which the stator is fixed, and at least two pins disposed spaced apart in a motor circumferential direction. The pins may be fixed to the carrier. The laminated core may include, for a respective pin, an associated guide through which the respective pin passes. The associated guide may have an associated lamination opening in at least a part of the laminations. The respective pin may be in contact with at least some of the laminations in an axial contact section. In the contact section, at least some of the lamination openings may have at least one tooth projecting radially inwardly. A respective tooth may extend circumferentially over a tooth segment such that an adjoining gap segment is free of teeth.

Abstract: An electric machine, e.g., an electric motor for a fan, and a method of manufacturing are disclosed. The electric machine includes a rotor that rotates in operation about an axis of rotation that is parallel to a motor axial direction, a stator extending in a motor circumferential direction, and a carrier extending radially with respect to the motor axial direction. The stator is attached to the carrier. At least one pin is arranged radially offset to the axis of rotation is fixed to the carrier and projects axially from the carrier. The stator is axially pressed onto the at least one pin so that the stator is attached to the at least one pin via a press fit and so that the press fit positions the stator relative to the carrier and fixes the stator to the carrier.
