A stepper motor has 24 North teeth and 24 South teeth. What angle change occurs on each step?
If a full step is output every 1 ms (and assuming it doesn’t slip), at what speed does the motor spin?

Solution

First of all we have to find the Angle per Step

360°/(4n) =

360°/[4(24)] =

360°/96 = 3.75°

Revolutions per Second

(4f/N) =

4(1000s)/(96) =

4000/96 = 41.667rps

-or-

41.667rps(60sec) = 2500rpm.

The speed of the motor spin is 2500rpm.
