Jim, according to Van Eck description, this machine is showing an "electronically governed DC magnetic motor".
We know now that there is no sensor on the claw shaft. Logically, you could find something fitted at the end of the motor :
- an Infra red sensor (with a coding wheel) or - a Tacho generator (In any cases , logically you could also find 4 wires coming to the motor.)
Did you replace motor belt ?
If yes, did you install a genuine belt ? If yes, is it a reinforced micro "V" belt (like elmo GS1200) ?
Here is Van Eck explanations concerning "GS1200" typical Belt grade :
"New belt, replacing your broken or stretched belt: The motor belt is a quality belt for Elmo GS-1200 (all versions). Brand product of current production. Given specifically for Elmo GS-1200 projectors from us in order, highest durability. Belt of rugged polyurethane with embedded special fiberglass-tension cords. We recommend the use of this particular form of V-belts, because here only the geometry to 100% corresponds to what Elmo has provided for these devices."
In summary, this means that installing this belt grade will improve speed steadiness too.
