Enco 110-0820 motor help

[njmike]

Hi, I'm a new member and this is my first post. Happy to be a part of the community. My father was a tool and die maker for 25 years and was my inspiration for setting up my own little shop. I acquired an Enco 110-0820 that has an interesting customization. The previous owner hooked up a Dayton 1.5hp motor that drives the original motor, and if you want to go into reverse you juggle some plugs around. I'm guessing the motor was bad and were unable to find a replacement. The capacitor was cut out of the circuit. I intend to take it apart and see if a new capacitor is all it needs, but was wondering if others found an equivalent replacement motor? Pictures show the setup and tag on the motor.

Whaaa? That's a hoopty setup for sure. I recommend putting it back single motor if possible- using the original motor as a jackshaft
is not efficient

What voltage are you wanting to run it on? The original 3/4 hp motor would be ok on 110 volts (if it works or can be fixed)
but the 1.5 hp unit should be on 220v. The 17 amp draw will exceed your house breaker rating (most are only 15) and
if the barrel switch isn't burned out by now it soon will be

I question the need for the flying cap if the larger motor has them already

Well that's goofy as heck! My only advice would be to replace both(!?) motors with one 3-phase motor, and get a VFD for speed control. 3-phase + VFD has other advantages too, like greater reliability (no capacitor to go bad), soft start, adjustable accel and decel settings, braking resistor option, etc. But having a dial to turn for on-the-fly spindle speed adjustment is the "killer app".

The 3-phase install is nice but 200-300$ investment (or more)
I would go with the existing hardware for now while I checked out the rest of the machine
That is a 9x20 inch lathe I think

Ah good point, I was going on the assumption that the rest of the lathe was good. If that's an unknown, then you don't want to spend much to find out.

But if you're buying a motor anyway, it's sad to buy another single-phase, when the 3-phase is such a quality-of-life improvement. And if you buy a good 3-phase motor only to find that the lathe is no good, you still have a good motor to use on another machine, or sell.

I have bought all my 3-phase motors used and all have been fine. Unless a bearing goes out (easy to detect by hand if it's bad), there's not much that can go wrong with them.

Funky. The cap you found bypassed is for the old motor, the new motor's cap is on the motor itself, under the humped cover.

1.5 ponies might be overkill anyway. If you want to stay at 110v, a 3/4 to 1 HP reversing motor would be the ticket. In the original location, of course.

So did you want to use the larger motor for now? It may work for light use without tripping the breaker but the best performance would
be to set it up for 220 volts and make a couple wiring changes
