The linear drives of the LinMot
slider and the fix stator. The requirements on this slide bearing construction are
exceptionally high, due to the enormous dynamic properties and acceleration of the
drives. For these reasons the following points must be observed:
Due to the surface pressure, a transversal forces have a stressing effect on the slide
bearing and on the lifetime of the drive. For this reason care should be taken in the
construction in order to reduce such transversal forces to a minimum, or to absorb them
by means of an additional guide.
The linear drives of the LinMot
elements and are not allowed to be used as guide or bearing elements.
In all constructions where the slider of the LinMot
longitudinally sliding machine part over direct coupling, an over determinate system
arises.
Figure 4-22: Compensation of parallelism errors
In order to compensate the inevitable offset and parallelism errors, a compensation
capable coupling (represented here by a bent line) must be used between the slider and
the moving machine part.
If the linear motors are mounted horizontal, the notch of the stator should be on the
lower side (see figures above). If mounted like this, the sliders mass is compensated by
magnetical forces in the stator.
