Slowing down a lathe...

[Frank Fusco]

Frank and others
"EVS" stand for Eltronic Variable Speed, this can be either a DC drive or a "Variable Frequency Drive". In order to use a VFD you must have a 3 phase motor so if one wants to do this as a retrofit they'll have too change out the motor. Many VFD's will operate on 1 phase, they create there own 3 phase. These can be had up to 2 HP for under $400 depending on the size and feature. I did a tutorial on how to do this sometime back if anyone wants to look it up.

Thanks for clarifying that. For $400.00, I would be better off saving the money and later investing in a different lathe. My Grizzly only cost $400.00 to start with. But, I will take the motor to a local shop and ask about adding a variable speed thingy. Might work but I have to be careful to not lose power as I don't have a lot to work with now.

Don,
I did a search on it and could not find it. You don't have another copy wholed away somewhere do you?

Thanks,
Bob

VFDs and 3-phase motors appropriate for lathes are available for "reasonable" investments via surplus routes, too. Not all lathes can physically support changing out the motor, however...'depends on the design, etc.
