Front View Of Stepper Motor Assembly
In order to see the assembly better, the pulley -- mylar tape -- is not attached
around the primary, 12-inch pulley, and the secondary,
1-inch pulley.
The grooves seen under each of the four allen wrench bolts are used for
tightening the pulley. In this image, the bolts are in
the
"Up" position, ready for the tape to be attached. Then, the
assembly is pulled or pushed down, the bolts are tightened, and the tape is
taught enough to hold the tube in position. (Note: The tube and all of
its components weighs approximately 35 lbs.)
