Aligning the motor components
The primary part is not symmetrically placed over the secondary
part, as the winding within the primary part is not centered.
Due to keeping the specified installation height at the bottom of the secon‐
plate
dary part up to the top of the primary part, the necessary air gap arises and
the motor reaches its projected power data.
NOTICE
After assembly, check the free movement of the motor components to each
other immediately. Therefore, move the versatile motor components by hand
over the complete travel length. The versatile motor components must be
freely movable at each position over the total travel length - without any con‐
tact to fixed motor components. This check can detect faulty assembly in time
( e.g. dirt under the assembly surfaces, faulty installation dimensions, insuffi‐
cient machine rigidity etc.).
The following specifications on the air gap refer to the use of sec‐
ondary parts without cover plate. If cover plates are used, the air
gap must be increased by the thickness of the cover plates
