Abstract:
An electric machine may be an external rotor motor with a stator and a rotor surrounding the stator. The rotor may be mounted on bearings so as to be rotatable around an axis of rotation relative to the stator, where the mechanical forces transmitted by the bearings of the rotor may be absorbed at least in part by the stator. The stator may have a coil winding for generating a magnetic field, the coil winding being surrounded at least partially by a casting compound. At the output, the mechanical forces of the rotor or the device transmitted by the bearings and taken up by the stator may be introduced into the stator largely via the casting compound. The casting compound thus reduces induced vibrations.
