Abstract

An electric motor and modular system of electric motors includes at least a stator, rotor, and a housing, the modular system including several variants of electric motors, e.g., within one size, the housing having a mechanical interface that is arranged for connection to a bearing support, the bearing support including at least a bearing seat for the B-side bearing of the rotor shaft, at least two different bearing supports being alternatively connectable to the housing, a first bearing support including an additional interface for connection to a bottom part of a terminal box, or alternatively to a bottom part for power electronics, and the first bearing support forming a housing for a brake and/or a fan, a second bearing support being constructed in one piece with a bottom part of a terminal box.
