Motor assembly through the mounting of the motor components
If other assembly methods are not possible, this complex method is applied.
Application example
The secondary section track is shorter than twice the length of the primary section. The
primary section together with the slide cannot be shifted to the side far enough so that all of
the secondary sections can be easily screwed into place.
For this installation technique, you must place a non-magnetic foil between the primary
section and secondary section track. This foil prevents the primary section from lying directly
on the secondary section track and causing physical damage.
High forces of attraction when the placing the primary section onto the secondary section
When the primary section is being mounted, high attraction forces (up to 40 kN) act in the
direction of the secondary section track. There is a risk of crushing!
• For this type of installation, a forcing assembly is required that allows the primary
• The stiffness of the forcing plate and the length of the jack screws must be selected in
• The high forces of attraction must be taken into account with sufficient reserve when
Procedure
1. Mount the secondary section track according to Chapter "Assembling individual motor
components (Page 150)".
