Design Consideration
The information provided here is critical to using linear motor components.
Design your system to comply with the following points to run safely and
successfully.
Motor Air Gap
Maintaining the air gap is critical to proper installation and operation of the
linear motor components. Use the coil, and magnet drawing in
on
to calculate the installation envelope dimension. Size the carriage,
bearings, and base plate to withstand the force of attraction between the coil and
magnet track. By maintaining the installation envelope dimension in your design,
the vertical air gap requirement will be met. The following diagram shows the
critical dimensions.
