| This page helps you select
to reach your desired top speed. Knowing
that, you can choose a motor here.
It also discusses moving the shortest
possible increment
Conditions:
- Motor controller (VXM)
operates at 400 half-steps per revolution
- Motor resolution is 1.8° per full
step or 0.9° per half-step. See note † at end of page.

*System step resolution or smallest repeatable move is dependant on system orientation, rigidity, friction, wear and applied load.
† Velmex also offers Vexta 0.9° motors. When driven by the VXM, resolution is 800 steps/rev. This effectively doubles the resolution but halves the translation speed.
