Hi

I have a Parvalux motor attached to my Marshall Watchmaker’s lathe, which bears a most uninformative specification plate.

Surely this is not a 75rpm motor??

……..and there’s no fractional HP rating

Does anyone else have a similarly useless plate on theirs?

Or perhaps it is a Friday job…

Lots of parvalux motors were sold with a worm gearbox fitted, and the plate gives the output speed of the gearbox. Taking the gearbox off is dead easy, leaving a normal speed motor (probably 1500 rpm nominal) , which is what I had on my little perris lathe.

I’m guessing it was originally fitted to one of their proprietary gearboxes, with a fixed reduction ratio, to give a 75rpm final output.
I have something similar, but don’t recall the make offhand.

I ‘m with the others, it is the output of the wormdrive box NOT the motor. I have a similar unit in the shed. Noel.

Strangely … SD9 doesn’t seem to feature on the current Parvalux website:

https://www.parvalux.com/

… but it’s worth browsing, to see their wide range of products.

That Parvalux motor is also unusual in being wound (or rated for) 220 and 380VAC. Because of its current application driving a watchmakers lathe I presume it is single phase although it is possible that if it was part of some industrial equipment a transformer might have been incorporated. The plate then showing the system rating just like the speed and the torque value (too high to be the motor spindle).

Well that’s a thread stopper!

No need for this forum, anyone with a problem can just find the manufacturers phone number and get help direct.

Thanks all

As the lathe was old, I was under the impression that Parvalux were obsolete, so assumed that I’d need to contact people who knew.

I have since sent a message with a photo to Parvalux to ask for more details.

Thanks all
