ABSTRACT:
Fixation of magnetic shells may be implemented in a motor housing in a simple manner in terms of design and assembly technology while guaranteeing great heat resistance. S-shaped sheet metal stirrups include at least a first stirrup portion bent radially upwards, slit longitudinally, open on the end side and at least a second stirrup portion which is bent lower radially. The first stirrup portion laterally surrounds fixation cams which may be stamped out of the motor housing in a radially inward direction. The second stirrup portion passes below the fixation cam and rests against the end sides of the magnetic shells. The S-shaped sheet metal stirrups are axially inserted between tangentially opposite end sides of the magnetic shells to press down on them.
