Parvalux motor – help please

[Mike WaldronParticipant @mikewaldron61652]

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.
