Hi All,
I have a Unimat 3 , which is I suppose 30 years old , the motor has died with low impedence and internal damage due to wear.
I am after a replacement motor if possible.
Does anyone have a motor which will fie ??
suggestions appreciated

This UK company seem to deal in Emco Unimat parts, could be worth a try.

This guy replaced his unimat 3 motor with a 24v DC motor and controller...

The Unimat4, Asian version of U3, has a more powerful and 100% duty cycle motor.

The original motor is a "universal" type brushed motor very much like a sewing machine motor of less than 100W power. The small rubber O-ring (5mm?) used to drive the spindle will not allow any more power to be transmitted. A used sewing machine motor with foot pedal variable speed may be a good candidate for a cheap replacement. However, the original Unimat motor was very well made, sure it cannot be fixed? Maybe this site has some hints:

Me personally, I would probably go for a 1/8HP 3-phase motor with a 100W VFD, but it may take some time to source both at a reasonable NOS price from eBay. I am right now doing something very similar: replacing the 70W single phase motor of my TOYO 210 mill head with a used 80W 3-phase motor salvaged from an old Swiss chemistry distiller found in the tip of an university, and an Omron mini v7 VFD (120W) I bought NOS on eBay for about $60. But it took a while to find all parts for that cheap. Chris
Hi All ,
Thanks for the reply's, I am unsure about the repair-ability of the motor, a friend is looking into it at the moment,
I would not mind the Unimat4 motor , I will look into the cost.
A 3 phase motor is not an option as I don't have 3 phase power.
Although the sewing machine motor could be a viable option.

I have a small 230V Bodine motor that I got years ago for one of those "one day" projects. It's rated at 1/50 hp though. The 3 phase motor suggestions aren't too bad though as at the sort of load you are talking about a small VFD would easily convert single phase into 3 phase.

Hi Jeff,
I don't know if it helps but I fitted a sewing machine motor to my shaper and it works a treat...so far.

That's probably a bit big for a Unimat, but looks great on the Douglas.Quote:

Thanks, the Douglas conversion is too big , I have found that Unimat 4 motors will fit, but the price tag is ridiculous , at over $300 Australian.
I am hopeful that we can rebuild the old motor.
