Embodiment Construction

[0042] exist figure 1 A device 2 for dynamic balancing of a rotating body 4 is shown schematically and in simplified form. In this case, the device 2 has an unbalance measuring device 6 for determining the unbalance of the rotating body 4 . The device 2 also has a laser 8 for generating a laser beam 10 with which material of the rotating body 4 is removed and / or additional material is added to the rotating body 4 depending on the determined imbalance. Unbalance measuring device 6 and laser 8 are signal-coupled to a controller 12 , ie a control unit.

[0043] Preferably, the rotating body 4 is rotatably supported on both sides at its end sides along its longitudinal axis in bearings 14 of the unbalance measuring device 6 , wherein figure 1 Only one bearing 14 is shown by way of example.

[0044] The unbalance measuring device 6 has at least one unbalance sensor 16 , which detects an occurring unbalance of the rotating rotary body 4 , for example by means of force and / or disp...

Abstract

The invention relates to a method for dynamically balancing a rotational body (4), wherein: the rotational body (4) is set into rotation; an imbalance of the rotational body (4) is determined; according to the determined imbalance, material of the rotational body (4) is removed and / or additional material (22) is applied to the rotational body (4); and the removal and / or the application is carried out by means of a laser beam (10) of a laser (8).

Description

technical field [0001] The invention relates to a method for dynamically balancing a rotating body, in particular a motor housing of an electric motor. The invention also relates to a device for dynamically balancing a rotating body and to an electric motor having a rotating body balanced in this way, as well as to the method for making a motor housing with magnet elements inserted therein Dynamic balancing applications. Background technique [0002] A rotational or rotationally symmetrical component, as a body of revolution, always has at least a certain degree of unbalance due to manufacturing or construction-related tolerances. In this case, unbalance is to be understood in particular as an asymmetric mass distribution of a (rotationally symmetric) rotating body, whereby its axis of rotation does not coincide or coincide with its principal axis of inertia. During the rotation of the rotating body, unbalanced forces arise as centrifugal or centripetal forces due to the i...
