Abstract

An electric motor construction kit for assembling a plurality of electric motors includes at least one module and a plurality of assemblies for constructing the plurality of electric motors. At least one assembly of the plurality of assemblies includes one or more modules of the at least one module. Apart from a cooling system of an electric motor of the plurality of electric motors, each module of the at least one module is constructed from carry-over parts.

First claim

What is claimed is:

1. 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.

2. The electric motor construction kit according to claim 1 , wherein: the at least one assembly includes at least one first individual part for at least one specific configuration or one specific type of electric motor configured to be constructed from the electric motor construction kit; and the at least one individual part, together with the one or more module of the at least one module, forms the at least one assembly.

3. The electric motor construction kit according to claim 1 , wherein: a first non-output drive side of at least one specific configuration or one specific type of electric motor configured to be constructed from the electric motor construction kit and a second non-output drive side of at least one further specific configuration or one further specific type of electric motor configured to be constructed from the electric motor construction kit are identical; and/or a first output drive side of the at least one specific configuration or one specific type of electric motor configured to be constructed from the electric motor construction kit and a second output drive side of the at least one further specific configuration or one further specific type of electric motor configured to be constructed from the electric motor construction kit are configured such that a multiplicity of individual parts is provided.

4. The electric motor construction kit according to claim 1 , wherein an electric motor of the plurality of electric motors is configured to be included in a handheld electric tool.

5. The electric motor construction kit according to claim 4 , wherein the handheld electric tool is one of an electric screwdriver, an electric drill, an electric saw, an electric grinding machine, and an electric gardening appliance.

6. The electric motor construction kit according to claim 1 , wherein the first configuration or first type of electric motor and the second configuration or second type of electric motor are electronically commutatable electric motors or electronically commutatable electric motors of different types.

7. The electric motor construction kit according to claim 1 , wherein: the bearing is disposed on a non-output drive side of an electric motor of the plurality of electric motors and an end cap disposed substantially directly on the stator module; and the rotor module is mounted in the end cap.

8. The electric motor construction kit according to claim 7 , wherein the frame module further includes a further rolling-contact bearing disposed on an output-drive side of an electric motor of the plurality of electric motors.

9. An electric motor construction kit for assembling a plurality of electric motors, comprising: at least one module including: a rotor module; a stator module; a fastening module; a frame module 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, 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, wherein, for cooling an electric motor of the plurality of electric motors, (i) a changed end cap having an opening is used as a carry-over part in the frame module, (ii) a changed ring having an opening is used as a carry-over part in the fastening module, and/or (iii) a changed end cap having an opening is used as an individual part, and wherein the stator module includes a slot seal.

10. The electric motor construction kit according to claim 9 , wherein: the at least one assembly includes at least one first individual part for at least one specific configuration or one specific type of electric motor configured to be constructed from the electric motor construction kit; and the at least one individual part, together with the one or more module of the at least one module, forms the at least one assembly.

11. The electric motor construction kit according to claim 9 , wherein: a first non-output drive side of at least one specific configuration or one specific type of electric motor configured to be constructed from the electric motor construction kit and a second non-output drive side of at least one further specific configuration or one further specific type of electric motor configured to be constructed from the electric motor construction kit are identical;
and/or a first output drive side of the at least one specific configuration or one specific type of electric motor configured to be constructed from the electric motor construction kit and a second output drive side of the at least one further specific configuration or one further specific type of electric motor configured to be constructed from the electric motor construction kit are configured such that a multiplicity of individual parts is provided.

12. The electric motor construction kit according to claim 9 , wherein the open frame electric motor and the closed frame electric motor are configured to be included in a handheld electric tool.

13. The electric motor construction kit according to claim 12 , wherein the handheld electric tool is one of an electric screwdriver, an electric drill, an electric saw, an electric grinding machine, and an electric gardening appliance.
