Embodiment Construction

[0011] The small electric machine according to the invention basically consists of a rotor assembly 1 , a housing assembly 2 and a current transfer assembly 3 . Individual parts of these components have been sufficiently disclosed in conventional electrical machines and are described here only to facilitate understanding of the present invention.

[0012] The housing assembly 2 and the current transfer assembly 3 have cylindrical configurations 2.1 and 3.1, which serve to accommodate bearings 2.2 and 3.2, in which the shaft 1.1 of the rotor assembly 1 is again supported.

[0013] In the further description it is provided by way of example that a bearing 3.2 is fixed in a cylindrical receptacle 3.1 and that the shaft 1.1 is axially displaceable in this bearing. The bearing can be not only a rolling bearing, but also a sliding bearing. Furthermore, it is further provided that the bearing 2.2 is a rolling bearing, for example a ball bearing, and that it is fixed in the associate...

Abstract

The invention provides a miniature motor and a bearing arrangement for the mimiature motor.

Description

technical field [0001] The invention relates to a small electric machine and a bearing device for the small electric machine. Background technique [0002] Today, small motors are used in different applications. For example as a power source for household appliances, hand tools, actuators in motor vehicles or the like. There are increasing demands on motors of this type which, in addition to having high power, also generate low noise. [0003] In this case, the basic noise source may be the bearing of the rotor of the electric machine, if axial and / or radial relative displacements of the electric machine shaft relative to the bearing may occur at the bearing point. Such movements may be caused by the tolerances necessary for the manufacture of the components of the electric machine, the limitation of which can only be achieved at great economic cost. [0004] Therefore, there arises a need to minimize the above-mentioned relative movement, without at the same time restric...
