Specifying the total length of the secondary section track
The total length of a secondary section track determines the number of required secondary
sections. It depends on the length of the desired traversing distance, the number of primary
sections on this secondary section track and, if applicable, the use of a Hall sensor box.
The calculation of the total length of the secondary section track specified here guarantees
the maximum motor force over the entire traversing distance.
An individual primary section on the secondary section track
If it is intended that only one primary section should be on the secondary section track, the
length of the secondary section track is calculated using the length of the required traversing
distance and the magnetically active length of the primary section (see the image below).
