Yeah it can work fine but a few things to watch for:
All motors should be identical in type, voltage, and rating if possible
Total cable length matters for VFD output, especially with reflected wave issues
Overload protection per motor (you lose individual motor feedback with one drive)
If one...
If the valve is working fine before and after the test, technically it hasn’t failed in functionality. But from a standards perspective, it didn’t meet IP65 and water ingress was detected, which disqualifies it per the spec, even if the ingress didn’t affect operation.
The customer seems to be...
Yeah defining perpendicularity to a curved surface like that is tricky. If you really want the hole axis normal to the R10 surface, you’d need to define datum A as a tangent plane at the point of intersection but that's a pain to inspect.
Might be cleaner to just define perpendicularity to the...
Yeah, Gates keeps that tooth profile info locked down pretty tight. Not in the public domain unless you license or reverse engineer.
Honestly, best bet if you're having failures is to measure a known-good OEM pulley with a CMM or profile scanner. Or buy genuine pulleys for reference if you can't...
