Another slow down option?

[James1]

The 750SL And the 750SH are in fact the same motor except for the circuitry. The SH has additional circuitry to protect it from overheating when sewing extremely thick leather at extremely slow speeds. Also, the 750SH has more functions programmed into the controller, but I’m not sure what those extra functions consist of. 

The 750SL is approximately $300 delivered in the US, and the 750SH is approximately $350 delivered in the US

Just curious if anyone else has purchased one of these yet? If so, what are your thoughts? 

@James1 Just got off the phone with Ryan Neel, I ordered the 750SL with NPS. I will be mounting it on my 441, replacing the servo & speed reducer.  I have been learning how to use my 1341 and it has a NPS and I have come to appreciate it.

Being able to keep a close eye on the needle and where it is going and not needing to watch out for where the needle bar stroke is at is useful, IMHO. I'm sure that if you are already a master at sewing machines that the NPS may not offer much use, I am not in this group yet.

I will report back how it works for me.

@CdK Nice! I took a Dremel tool and opened up the front of my needle  presser foot so I could see it better. Please let us know when you get it installed.

@James1Good tip, I have an open slotted presser foot on my 1341 but the slot is too small to really see the needle. I have fitted parts from Hennigan Engineering & Precision and an Australian company whose name eludes me on my 441 to better suit my needs. These include the narrow feed dog & plate also narrow presser feet which is open and the needle is easy to track.

I’ll let you know once I have them installed. I contacted Ryan a little while ago and updated my order to 2 750SL units. I’ll probably need different belts as the speed reducer will be removed.

I have a singer 16-188 w/ a standard servo motor and no speed reducer.   Depending on how thick the product I'm sewing I can go very slow but a slight push on the pedal it does speed up.  So does the HM-750SL have a long travel on the pedal to keep from having to lightly feather the pedal to keep control of speed?

[James1]

The pedal has a pretty short travel, but you can set the speed limit and push the pedal to the floor, but it will only go as fast as your setting, if that makes any sense

I purchased the 750SL several weeks ago and have been running it hard since then. It easily handles three layers of 9 ounce Latigo, even when I just tap the pedal to advance it one stitch. My 1 hp Consew motor struggled with this and often just stopped. The real challenge for me is sewing relatively slowly through 7 layers of 21 ounce duck canvas. The Consew always bogged down, but the Kinedyne handles it without any sign of struggle, even with a 23 needle. By the way, this is on a Juli 1508NS.

What I really like about it is that the needle stops pretty much on a dime when I take my foot off the pedal when sewing fast. My other motors seem to give way to momentum and allow the machine to sew up to three stitches before coming to a halt. It’s as if there is a brake in the motor. 
 

I can’t speak to durability since I’ve had it such a short time, but based on the first few weeks of use, I highly recommend this an an alternative to a speed reducer, especially given how well the needle positioner works.

For those on continental Europe intressted in this servo motor (Kinedyne), this might be a supplier of your choice.

I send an email to them (first to Kinedyne to get info on their representative in Europe) to ask for price etc. Got an answer at last - see below - but I had not the patience to wait and bought a servo motor from Global instead. By the way I have none affiliation what so ever with this company.

The email from them:

Hi

thanks for your enquiry

 

We are Kinedyne distributors and price for these motors is 400€ +vat22% with syncronizer for needle positioning and our support if you need help during fitting.

 

Do the machines has any pneumatic?

Which model is?

 

Thanks

Simone

I wanted to chime in real quick on the 750SH. I am in Canada and Ryan Neel had the motor to me in 3 days! WOW what an awesome motor. I am using it with a 205 style machine from Global. My machine was used and came with a Reliable style motor (grey plastic cover) and was not great. A speed reducer would have cost me the motor alone. The Kindyne is super slow, and will easily go through my 2 layers of 2.5mm chrome tan on a 27 needle. It is well built, of course time will tell how long it lasts. 

The best thing about the motor setup is it is very responsive. Pedle movement starts it slow and the ramp is nice. Once you let up it immediately stops or slows. Very easy to control. I didn't get the NPS because I didn't want to bother with the flywheel I have and with the speed control I don't miss it. I have had the typical brushless servo motor coming from just about every industrial brand (they all look same with the logo changed) and didn't like the feedback. 

If anyone is questioning the Kinedyne it is a huge value and can transform your machine performance.

@adventureleather Thanks for your report and especially the video.  It really shows how it runs.

I really want one of these, I just can't justify the expense with as infrequently as I use the machine.

nice video, thanks for sharing

 

why you choose 750SH over 750SL? 

is it coming completed with a needle positioner? if not - will it work with non-Kinedyne one? 

 

and a main  issue - is it really substituting a wheeled speed reducer?

Thanks Al. Totally understand. I had no choice..needed a better motor than what mine came with haha.

Great questions. The SH model has more circuitry to help with the heavier machine for the torque of turning a bigger flywheel. I think for heat if you use the slower RPM settings. I don't recall the HP rating on the SL vs SH. The motor is well built very solid metal. Ryan mentioned to me that some saddler makers still like the reducer for the torque ability because they are used to it. But the pulley on the 750 is super small and the motor goes to 50RPM. For me it is super slow and powerful enough for my uses, 2.3mm 2 layers mostly and it is sewing fine with glue. I haven't trie thicker material. In terms of speed, yes no speed reducer needed..its very slow without. 

I didn't get the needle positioner. I didn't want to spend more and I haven't missed having one to be honest. The motor slows down immediately so finding BDC or full up is fine and easy.
