Kinedyne servo motor

[fibersport]

Just got my Kinedyne servo motor last night from Neel's Saddlery.  Ryan is a great guy to deal with but the servo motor is unbelievable.  Granted I'm new to sewing but the power and especially the slow speed of this thing is fantastic.  To me, this is similar to comparing a manual transmission to an automatic.  Don't get me wrong, I love manuals but not having to deal with finding the friciton point of a clutch motor or dealing with the instant ramp up of a cheaper servo motor is priceless, you get a true one stitch at a time.  I built a speed reducer and it worked but not like this motor.  It's smooth as silk, powerful, quiet and everything I've been trying to get out of a motor.  The HM750SL, HM750SH or even the HM1000SH is what you want to look at they all have the 50 rpm lower limit.  I know some have kind of written these motors off but everything they say about them is true.  I highly recommend the Kinedyne motor - and I do not get anything for saying this -

Glad you like it. Ive heard good things about them as well. 

What is the differences between the 3 models you listed?

I've been interested in these motors for a couple of years but this is the first actual report of one in the wild.

Thanks for posting!

From what I was told by Ryan (if I remember correctly) the 750 SL is let's say the base model that runs as slow as 50 rpm and is rated at 1 hp.  The 750SH is the same but is built to run on the slow side longer if that makes sense and is also rated at 1 hp.  The slower they run the more heat is generated so I believe it has to do probably additional heat sinks in the controller.  The 1000SH is the best one, it too can run all day at very slow speeds and is rated at 1.3 hp.  

Just last week I had tried one of the generic "750" watt motors with needle positioner from Amazon.  I think it was on and off my machine in two days, it would have been sooner but I still have a day job.  The Kinedyne is so much more refined, is much heavier is very well built and the positioner is super accurate.  The generic one would drift all over the place, the Kinedyne is spot on every time.  I really like the controller being separate so ou can easily change settings without having to crawl under the table.

They are not cheap, but honestly you get what you pay for.  A generic digital servo runs about $75-100, a good analog servo is now about $175.  The Kinedyne starts at just under twice the analog model.  I would rather not quote Neel's Saddlery's pricing and suggest you contact him yourself.  And don't worry about dealing with a smaller company, he is a top notch guy.  I did wrestle with the cost, however after getting it I really don't regret it.  You might watch the videos from The Thoughtful Woodworker, they helped me make up my mind.

I purchased three of the 1000SH motors/controllers from Ryan and I run gargantuan machines (Singer 7-33, 11-20 and 11-22) with them, working heavy leather at slow speeds, no speed reducers required. (Running 230/26 needles and #346 threads.)

I can't say enough good things about Ryan and his service both before and after the sale.  I will say that the manual, highly technical, needs some clarification at a few points,  but for most applications, it's "plug and play."

In addition, because of the nature of standard rubber (or rubber composite) V belts to take a "set" while at rest, especially around the small pulley on the motor, I use an "ACCU-LINK" adjustable link V-belt (the green one) with the 3L profile.  Runs without distortion or doesn't produce the black rubber dust common to rubber(ized) belts as they wear.  Stupidly expensive, but easy to fit and re-adjust as necessary, and clean running.

I have no doubt these motors are good (they're made by Hightex) but here they're a ridiculous price. I bought "generic" servos and built speed reducers for considerably less cost and they all work fine for my needs. I guess for commercial usage the cost isn't so much a factor - but how many factories want such a slow speed machine? In most factories the speed of making something is very important (time is money) so paying extra for a slow speed you don't need is wasting money. It seems to me it's a pretty specific (and limited) market this motor is catering for?

Don't get me wrong, I'd love to change my servos for these but the cost would be absurd, ain't going to happen.

A little pricey yes but this is the 4th motor I've bought chasing what I was looking for in a servo motor.  I'm thinking I've gound it.  Now if I add up all the money I've spent on the previous motors, I could have bought two of the Kinedynes and been satisfied all this time.  Sometimes you just have to wiegh what's important to you, a few dollars for less frustration works for me - besides I had sold some other stuff from another hobby that helped fund this.
