Jan:

After reading all the posts on this subject I am a little confused.
I have three Vexta (Oriental Motor) PK268M-02A steppers that will be
driven by Gecko 201 drives. These steppers are 187 in/oz.; 2A/phase;
4.5V; 2.25 ohms/phase; .9 deg; 6 wire motors. If I run these motors
"Half Coil" would I run them @ 2amps or 4amps? With my cheap volt
meter, I get a resistance of 4.8 ohms full coil & 2.5 ohms half coil.

Thanks: Gerry
