Stepper motor question??

[weke934]

If a stepper motor advances 625 degress when given 250 pulses.

Whats the step rate??


Thanks

625/250=2.5

Step Rate = 2.5 degrees/step
you would have to have 144steps/revolution stepper motor to get the 2.5 degrees /step rate.
Very odd!
Are you sure it's advancing with every step?



Most steppers have 48 step per revolution (7.5 degrees/step or 3.75degrees per half step).

You should get lots of brownie points for doing somebody else's homework

Not really, 1.8 degrees per step (200 per rev.) is quite common too, for applications where a smoother output is required.
