Abstract
An electric motor for driving an inertia separator is provided, including a stator and a rotor. The stator is arranged in a stator space enclosed by a stator housing. The rotor is arranged in a rotor space concentrically with the stator with regard to an axis of rotation. A ring gap is formed radially between the rotor and the stator such that it separates the stator space from the rotor space. A housing bottom includes a nonmagnetic section extending through the ring gap. An inertia separator includes a second rotor operably connected to the rotor. A separator housing encloses a void containing the second rotor, wherein the housing bottom is arranged on the separator housing on a side facing the electric motor such that the nonmagnetic section of the housing bottom defines an opening in the rotor space that is oriented towards the void.
