Usually stepper motors will be having 5 or 5 wires with 2 pair of coils and 1 common,so we can easily find out the terminals. but in this how I can find out the common and other terminals, I want to interface to the 8051 controller for the complete PROXIMITY ROBOT project since with that stepper motor I can't make the Choasis and other thing, since it is big in size.

CAN ANY ONE HELP IN THIS MATTER.

REGARDS n THANKS

Below is a digram of Bipolar stepper motor



To check which wire for which coil.. simply do the connectivity test]]> contact@nospam.com (Ajay Bhargav) Wed, 01 Aug 2007 01:24:14 -0700 http://www.8051projects.net/forum-t1360.html http://www.8051projects.net/forum-t1360.html i only discussed about Unipolar Stepper motors (5 or 6 wires). But i think i have to write for Bipolar motors too ]]> contact@nospam.com (Ajay Bhargav) Wed, 01 Aug 2007 03:49:41 -0700 http://www.8051projects.net/forum-t1360.html http://www.8051projects.net/forum-t1360.html contact@nospam.com (Ajay Bhargav) Sat, 01 Sep 2007 13:09:30 -0700 http://www.8051projects.net/forum-t1360.html http://www.8051projects.net/forum-t1360.html ]]> contact@nospam.com (Ajay Bhargav) Sat, 01 Sep 2007 13:11:35 -0700 http://www.8051projects.net/forum-t1360.html
