Maxon Motor has developed a 16mm spindle drive. Designed to be easily configurable, the drive system has integrated axial bearing for high loads. There is a version with a metric M6 spindle or Ø 5 mm ball screw.
According to the manufacturers, gearheads, motors, encoders and controllers from the company’s standard program have been selected to drive the spindles. The individual components of the spindle drives are matched to each other in order to deliver high-efficiency drive performance.
A central component is the axial bearing, which must withstand the high tractive and compressive forces of the spindle.
There are 14 different reduction ratios in the planetary gearhead available, from 4.4 up to 850:1. Depending on the reduction ratio and the type of spindle, this makes it possible to achieve feed forces between 35 and 370N and even up to 400N for short durations.
DC or brushless EC motors can be used to drive the system. In total, nine different motor types are available.
