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 drawings in the LX-Series
Iron Core Linear Servo Motor Technical Data, publication LX-TD001 and the
cooling plate drawings in the Kinetix Motion Control Selection Guide,
publication GMC-SG001 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.
