Embodiment Construction

[0041] By means of a fixed definition of the construction of the motor as either a fully supported motor (full case construction) or an open frame motor (open frame solution) and a fixed definition of the conduction of the air flow at or through the motor , apply the same motor to meet different requirements, eg limited in different tool types. This means that a dedicated motor must be used for each tool type. For example, in the case of product applications in (strongly) polluted environments (conductive dust, magnetic dust, e.g. on angle handle hand grinders), it is necessary or at least advantageous to use enclosed electric motors (also called enclosed motors) of.

[0042] Only relatively low powers of such electric motors can be achieved with some possible solutions for cooling such canned motors. If the same motor were applied to a product used in a less polluted environment (such as a hole saw), then only lower power could be achieved here, although the same motor with...

Abstract

The invention relates to an electric motor construction kit for assembling a plurality of electric motors, in particular for mounting at least two configurations or types of preferred electronically commutated electric motors. The 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 electric motor assembly is constructed from general parts. In addition, the invention further relates to an electric motor or diffent types of electric motors, in particular electronically rectified electric motor or electronically rectified different types of electric motors, preferably full-bearing motor and / or semi-bearing motor (0), has / have a support module or a support module in the electric motor assembly, the support module of the motor is suitable for a second motor in different type, or different motors have substantially the same support module.

Description

technical field [0001] The invention relates to an electric motor assembly for mounting a plurality of electric motors, in particular for mounting at least two configurations or types of preferably electronically commutatable electric motors. The invention also relates to an electric motor or different types of electric motors, in particular an electronically commutatable electric motor or several different types of electronically commutatable electric motors, preferably fully-mounted and / or semi-mounted motors. Furthermore, the invention relates to a manually operated electric tool, an electromechanical tool or an electric drive, which has an electric motor according to the invention formed from an electric motor assembly according to the invention. Background technique [0002] In the prior art, electric motors or electric (auxiliary) drives are known, for example as drive motors for manually operated electric or electromechanical tools, or for example as servo drives for ...
