BIAX 7EL 220v Replacement Motor?

JohnAU · Dec 15, 2022

Hello, I have an older Biax 7EL 110v scraper and I was wondering if anyone knows if there is another tool with 220v motor that can replace the current one? I currently run it off a 220v to 110v transformer but I am looking at options as I can’t seem to find replacement brushes and I would like to have a speed controller.

Or you could just do what many do and stick a speed controller in line with the power lead on an extension.

It is probably an off the shelf motor from another tool (as that is Biax's way) but one from so long ago finding it is going to be difficult I think. You might get lucky with a google image search/google lens but chances are you need to do a retrofit of some sort. (I would cut off the pinion and graft it onto a new motor)

Here is one example. https://www.practicalmachinist.com/forum/threads/cordless-blue-biax-retro-fit.407935/ cordless would be nice, although I would use a higher quality motor.

That's a good idea, because there is definitely no motor known that replaces the Biax 7EL motor directly.
There is a thread (german language) with pictures that shows how to do:

Biax 7 EL - Neuer Motor? - Seite 2 - Zerspanungsbude

Addendum:
This brush replaces the original one of the Biax 7/EL motor:

KK 486 Kohlebürste 5 x 6,4 x 11 mm

Be careful to choose a speed controler that won't damage the windings of the old motor.

Which is what I did do in fact. I have updated the thread.

Thanks for the replies, I think I’ll work with the current 110v motor for now. If it ever dies then I might look at retrofitting a new one.
