In Reply to: Have you closely inspected that pulley.... posted by tubesforever on September 18, 2006 at 23:58:05:
Yes I have inspected it and yes it is certainly all one piece.I do think Papst made motors to OEM specification, that is, after all, their business. The same holds today - Maxon will make any motor configuration you want as long as you want 10,000 of them.
Follow Ups:
Yes, and we will most likely press new pulleys over the machined part. My thoughts are to make a simple nylon collar that presses over the shaft with the pulley extended beyond where it is currently located. This would make for a longer shaft that is more like the Empire's, but suitable for string.
Otherwise it would be my design and it might or might not be successful ;-)
but IIRC correctly, the ROK motor has its own external housing and is larger and heavier than the Empire (pictured)The spindle is pressed onto the motor shaft as one piece on both motors; the Empire has 331/3 /45/78 steps
I'm 99% sure these wouldn't interchange from one T/T to the other, tho' these are from the same era and maker so indeed, v. similar designs

No. The ones that we are using are identical, except for the shaft. The color and the top plate are different, but we are indeed talking about the same motor. The Rek-O-Kut and Empire are strikingly similar in mechanical features. This makes the more ugly Rek-O-Kut ideal for a ground-up DIY.
