Definitions
- the drive module has a direct drive, the direct drive being set up to act magnetically on the cycloid disk.
- the cycloid disk interacts with the magnetic field of the direct drive and is deflected or rotated via this interaction, in particular eccentrically.
- at least a part, in particular the (primarily) inner part through which the magnetic flux passes, of the cycloid disk consists of a, preferably particularly, suitable magnetic material.
- the drive module in particular the combination of drive and cycloid gear, can thereby be made significantly more compact, in particular the required installation space can be reduced or made smaller, with the masses and/or mass inertia being advantageously reduced in one embodiment.
- the direct drive has a pole shoe ring with pole shoes, the pole shoe ring being arranged in the opening of the cycloid disk, in particular on a central axis of the drive module.
- the pole shoe ring forms an air gap with the opening of the cycloid disk, so that in particular an eccentric movement of the cycloid disk about the central axis is or is possible.
- the pole pieces are aligned radially outwards in the direction of the cycloid disk. “Radial” is preferably understood here as perpendicular to the central axis.
- the direct drive has a pole shoe ring with pairs of pole shoes, which form a north pole and a south pole, particularly in the axial direction. In one embodiment, this makes it possible to increase the effect of the direct drive.
- the pole shoe ring has a central opening, in particular a feedthrough, in particular a rigid central opening or feedthrough.
- this can be designed as a hollow shaft, which is formed through the, in particular through the entire, assembly of the drive module, in particular without impairing the function of the drive module.
- the central opening is arranged coaxially with the pole shoe ring; in particular, in one embodiment, the center of the opening lies on the central axis.
- the drive module has at least one, in particular at least two or at least three, and/or at most five cycloid disks.
- each of the existing cycloid disks has a direct drive, in particular a pole shoe ring.
- the cycloid disks are arranged in such a way that an overall center of gravity of the existing cycloid disks is or remains stationary during a wobbling movement.
- the phase of the cycloidal disks is shifted relative to one another by 180°, in particular in the case of two cycloidal disks, or by 120°, in particular in the case of three cycloidal disks.
- the phase shift is 3607N, where N is the number of cycloid disks present.
- the drive module can be made possible for the drive module to have low vibration/lower vibration than, in particular, one or more cycloid disk(s) which have a center of mass of the cycloid disk(s) that moves during the wobbling movement of the cycloid disk(s), in particular not being stationary.
- a cycloid drive comprises at least one drive module described herein. In one embodiment, as already described herein, this can reduce a moment of inertia of the drive, in particular enable strong or stronger robots and preferably contribute to an improvement in the aesthetics and / or the reduction of the disruptive contours of a robot.
- the cycloid drive is small, in particular with less mechanically loaded parts or assemblies.
- a method for controlling a drive module for a cycloid drive in particular a drive module described herein, is provided.
- the method includes determining a position of the cycloid disk.
- the method includes determining the position of an output of the drive module.
- the method has the actuation, in particular commutation, of the at least one electromagnet of at least one of the pole pieces, in particular the actuation of at least three electromagnets of at least three pole pieces, in particular in such a way that the cycloid disk of the drive module is positioned and/or moved , based on the determined position of the cycloid disk and/or the determined position of the output.
- an output 40 is shown schematically in FIG. 1 via the external support with output teeth 45.
- the wobbling movement T of the cycloid disk 10, which is triggered by (targeted) activation of the electromagnets and thereby forms a moving air gap 21 between the cycloid disk 10 and the pole shoe ring 13, leads to a rotation of the output 40, shown here as an example.
- the opening 6 offers the possibility of cables, in particular Data cables and/or electrical supply lines are to be guided through the drive module 1. These then do not have to be guided over the outside of the machine or robot.
- the drive module, with its wobbling movement T of the cycloid disk 10, can alternatively be designed for an output via the internal support through the webs. This alternative is not shown in Fig. 1.
