re:Sanyo "Step-Syn" Stepper Motors

Hugh,

These are 34 single stack motors ~150 oz.in. They will work fine on
your proposed machine. Have used a slew of these myself. Pay
attention to the 2degree step (not 1.8) and setup accordingly.
Use 1/2 the winding if you go bipolar, they were originally used
unipolar by IBM.

The white and black are center taps. Red goes w/ red-white. Blue goes
with blue-white.

Did your printer also have the giant encoders(black plastic,
sometimes clear) driven by a gear on the motor? Never got around to
using these, still have a bunch in storage somewhere.

Hope this helps.

P.S. I used a 35vdc supply and 2A (modified)half-step drivers with
these. I set the "single coil on" current to 2A, and the "2 coil on"
current to 1.4A.
