Decent "Cheap" Servos?

[Cumberland Highpower]

I'm looking for a cheap (yet decent) servo for a machine I'm setting up.  It's a wimpy machine that I want to run at a pretty low SPM. as low as 30 maybe.

Thinking to order in an ISM CB-55D in 110v, although I looked a bit at some of the Reliable Sew Quiets as an option.  I don't know much about the Reliables, how low can they go? 

I've got a couple ISM SV-71s in 210V.  While I REALLY like these I do have some problems with my supply voltage. At times in summer my line voltage goes above 246v and when it crosses that threshold the ISM's will error out.  That's not really a "problem" in a big way. I just plug in a small idler motor in the  circuit that gets it down a bit and problem solved.

Anyone have any experience with the CB-55D?  How about the "Reliable" 6000 and 6050?

Get hold of Bob at Toledo Industrial Sewing Machine Co

I've had great service from him including the servo he sold me for an old singer machine

Besides that . . . he's good people . . .

And yes . . . they're in Toledo Ohio

May God bless,

The Enduro drives work pretty well.  The smaller unit, SM645B-2P is for sale on Ebay (https://www.ebay.com/itm/165684311695).  I have used 2 0f these units, and except for the positioner control have been very satisfied.  They make a larger unit, SM1050-2PF.  The positioner control requires a simple modification to get it to operat properly.  I don't know about th SM1050, but there are several people who have commented that the SM645 unit works just as well on 120VAC as it does on 220AC;  I haven't tried it and run mine on 220 VAC.  These might be other options and are very inexpensive.

Dwight's right...experience is your best route. Talk with Bob at Toledo Sewing Machine. Aside from purchasing my CB3200 from him, he hooked me up with a servo motor for a 1940 manufactured Singer 31-15 a few years back...along with a few other parts & pieces I needed to get'er running good for canvas/cloth/etc. Plus, Bob's a frequent contributor to these forums with his extensive expertise. Call 'em up on the phone...there'll be no regrets.

Hey Gerry I actually saw those units on ebay as well.   I've not owned one, but did some research a little.  Seems like most commenters said they didn't have good  low speed control?  If you have 2, how do they suit you on the slow?

Most of my shop is wired with Nema 6-20 outlets, but might want to take this machine other places from time to time because of it's smaller size.

I have a 4:1 reducer on my machine, so "slow" is not a problem.  (I also know that there is a mod to give more range on the speed control to enhance low speed operation.  I would use a higher ratio speed reducer so that the motor can run at a higher speed and give you the lower speed that you require.  This is better for the motor.

Also, just for curiosity, I just finished checking to see how/if it would run on 120VAC, and it ran perfectly, full torque, full range of speed, etc.  I assume the internal supply is universal and can handle all the way to 220VAC and that they change the label to suit the market.  So, you can run it on 220 in the shop and have a small adapter cable to run it on 120 when in the field.
