Electric motor construction kit and electric motor

An electric motor construction kit for assembling a plurality of electric motors, comprising:

• at least one module including:
• a rotor module having a rotor body, a magnet, and/or a balancing disk;
• a stator module having a stator body, a winding having slot insulation, an end plate, a connecting plate, an electrical connection, a connection for radio interference suppression, and/or a slot seal;
• a fastening module having a tensioning element, a force introduction element, a first ring and/or a second ring having an opening for cooling;
• and a frame module having a first end cap, an armature bearing, a cap, a magnet wheel, a sensor circuit board, and/or a second end cap having an opening for cooling, and configured for mounting an armature shaft of an electric motor of the plurality of electric motors, and the frame module is configured such that both a first armature shaft of a first configuration or a first type of electric motor and a second armature shaft of a second configuration or a second type of electric motor can be mounted with the frame module;
• and a plurality of assemblies configured for constructing the plurality of electric motors, at least one assembly of the plurality of assemblies including one or more modules of the at least one module, wherein the at least one module does not include a cooling system of an electric motor of the plurality of electric motors, wherein each module of the at least one module is constructed from carry-over parts, and wherein any electric motor configured for construction with the electric motor construction kit includes the rotor module, the stator module, and/or the fastening module.
