| 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
- Standard Motor resolution is 1.8° per full
step or 0.9° per half-step with the VXM.
- To increase resolution and/or decrease speed you might prefer the Vexta M Series High Resolution Motors†

*System step resolution or smallest repeatable move is dependant on system orientation, rigidity, friction, wear and applied load.
† Velmex also offers Vexta High Resolution 0.9° motors. When driven by the VXM, resolution is 800 steps/rev. This effectively doubles the resolution but halves the translation speed. Speed can also be reduced with thei insertion of a gear head between the motor and stage.
