step motor controller

hi

I try control an step motor, but I don't have datasheet of motor, because I remove them from printer.

this is my motor reference 17pm-k041-p2f:

**broken link removed**

on my program I make:
output_high(PIN_B7);
delay_ms(10);
output_low(PIN_B7);
delay_ms(10);
output_high(PIN_B6);
delay_ms(10);
output_low(PIN_B6);
delay_ms(10);
output_high(PIN_B5);
delay_ms(10);
output_low(PIN_B5);
delay_ms(10);
output_high(PIN_B4);
delay_ms(10);
output_low(PIN_B4);
delay_ms(10);
Click to expand...

in each pin I have an NPN MOSFET.

my question is how I know where PIN put each thread, I have 5.... how I can dicide this?

best regards.
 

Re: step motor controller

First, try to identify wires of your stepper motor ..
Here is a procedure that may help you:


Then you can start generating stepping sequences ..
