cation007 Posted January 29, 2006 Report Share Posted January 29, 2006 I have a stepper motor salvaged from a printer. I can see that it draws 1.3A/ph. I also salvaged SI 7300 chips from it.I am trying to drive the motor with that chip, but fail to do so...I dunno y. The power supply to the chip was 12V 3A.I want to know wheter this didnt work coz of this low voltage!I am sure that both motor and the driver chip works!Plz help me!Thanks in advance!
