End position shock absorber
Damage on machine or motor components
when driving against hard stop!
WARNING
⇒ Use suitable energy-absorbing end position shock absorber
⇒ Adhere to the specified maximum decelerations
Suitable energy-absorbing end position shock absorber must be provided in
order to protect the machine during uncontrolled coasting of an axis.
If the maximum deceleration is exceeded, this can cause the primary part to
come loose and damage the engine components.
●
When moving against a fixed stop, the maximum permissible
deceleration must be limited to 250 m/s² by a suitable ener‐
gy-absorbing end position damper.
●
The necessary spring excursion of the shock absorbers
must be taken into account when the end position shock ab‐
sorbers are integrated into the machine (in particular when
the total travel length is determined).

Axis cover systems
Depending on the application, design, operational principle and features of
synchronous linear motors, the following requirements on axis cover systems
apply:
●
High dynamic properties (no overshoot, little masses)
●
Accuracy and smooth run
●
Protection of motor components against chips, dust and foreign objects
(in particular ferromagnetic parts),
●
Resistance to oil and coolant lubricants
●
Robustness and wear resistance
Different covering systems can be used, like bellow covers, telescopic covers
or roller covers. A suitable axis cover system should be configured, if possi‐
ble, during the early development process of the machine or system – sup‐
ported by the corresponding specialized supplier.

General
The following figures shows a complete linear direct drive, consisting of a
synchronous linear motor, length scale system, drive controller and superor‐
dinate control.
