Besides adhering to the individual maximal loads, the following equation must comply if there are multiple forces and moments acting simultaneously on the linear motor:

$$
\frac{|Fy|}{Fy\_{\text{max}}} + \frac{|Fz|}{Fz\_{\text{max}}} + \frac{|Mx|}{Mx\_{\text{max}}} + \frac{|My|}{My\_{\text{max}}} + \frac{|Mz|}{Mz\_{\text{max}}} \leq 1

ELAX® direct drive with linear motor – precision
\
without wear

The contactless ELAX® direct drive with linear
\
motor operates completely wear-free, thereby
\
guaranteeing consistent accuracy throughout its
\
entire service life.

The mechanical guide is the element that
\
determines the service life. Our ELAX® Ex guides
\
with cross roller guidance offer decisive
\
advantages over conventional recirculating ball
\
bearing systems: Thanks to the advantageous line
\
contact (instead of point contact with ball
\
bearings), the load is distributed more evenly. The
\
material alloy of the cross rollers and guide rods,
\
which is specially designed for durability, ensures
\
high robustness and precision.

The cross roller guides are characterised by the
\
following properties:

* High precision and stability
* Low maintenance
* Less sensitive to dirt than closed ball circulation
  \
  systems

Our experience over many years shows that with
\
moderate loads, regular maintenance and a clean
\
environment, service lives of over 350 million
\
cycles can be achieved.

Actions with which life time can be extended:

* Trajectories with curve profiles instead of
  \
  trapezoidal profiles (XENAX® Servo controller,
  \
  default value S-curve profile = 20%).
* Dynamics not higher than needed.
* Completing non cycle time critical motions
  \
  slower.
* Avoid pollution in the guides.
* Cleaning and lubrication of the guiding beams
  \
  every 12 months.
