You can't

You are missing too much information and there are many complex interactions that come into play.

Even if you had it all, the math would be ridiculous.
Build and test- reality doesn't lie.

 

I found this resource:
http://www.orientalmotor.com/technology/articles/article-speed-torque-curves-for-step-motors.html

and also this conversion tool
http://www.linengineering.com/resources/conversion-calculator/

which made me understand several things...
however in my spces sheet it says 240 RPM is 1600 pps... But in the conversion tool (and a formula I found elsewhere) 240 rpm is 800 pps!

I wonder why this is so? Perhaps they are calculating with half-step mode??
Help please

 

I always thought that the PPS(pulses per second) was a direct result of the step angle of the motor, such as 200 steps per revolution equals 1.8 degrees per step

 

Quick question.. (I have googled it to no avail)

What is 1-2 phase?? (excitation)

Is this the same as half-step?

Thanks

already did that and as I said to no avail. All documents mention 1-2 phase excitation as something you already know the definition of, but no mention of a definition.

I am guessing it is another name for half step. Can someone please confirm or deny this?

Thanks

 

Confirm it. Check this link, around half way down the page. http://www.nmbtc.com/step-motors/engineering/full-half-and-microstepping/

 

Thank you. I guess then it is half stepping.
