Stepper Motor Maximum Speed and Power Calculator
Stepper Motor Maximum Speed and Power Calculator. Stepper motors are normally used for positioning, and are not known for their speed. This calculator computes the maximum speed of a stepper motor, which is limited by the time it takes for the coil to energize to it''s maximum holding current, and then deenergize as polarity flips.
