Abstract: The invention relates to an electric motor having a rotor and a hollow-cylindrical stator which carries exciter coils (3), the stator being connected at the end face to a stator carrier (8) of the electric motor and having stator teeth (1) which extend in an axial direction and which each have at least one pole shoe (1a, 1b), at least one coil winding (3) being wound around a stator tooth (1) in each case, there being arranged at one or both end faces (1St1, 1St2) of a stator tooth (1) and/or the pole shoes (1a, 1b) thereof an end face element (2, 6) which is/are at least partially wrapped or surrounded by the coil winding (3).
Abstract: An electric motor may include an outer rotor and an inner rotor, with a stator, which carries the excitation coils, formed as a hollow cylinder and engaging in the pot-shaped outer rotor and being connected to the housing or to a part of the electric motor fixedly connected to the housing, and where the electric motor may further include a water cooling and an air cooling system.
Abstract: The invention relates to a stator with a plurality of field coils, wherein the yoke teeth, which bear the field coils, of the poles are connected with their free ends to a stator ring, and wherein adjacent pole shoes or poles are connected to one another.
