Which Servo Motor For Consew 206Rb-1

[paprhangr]

Im confused ,what motor works best for high tork at low speed up to 3/8" leather on a consew 206 rb-5

Well, after doing some research, it looks like there are a lot of good reviews on the Reliable SQ 5000...or I could get a reducer. However, the reducers looks to cost as much as the motors themselves. Are there and inexpensive alternatives for a reducer? It doesn't make much sense to spend money on just a reducer if I can get a servo motor for the same price. As I am not working on leather, just canvas and sailcloth, I think the servo would have sufficient torque at slow speed. Right?

I have a consew servo on my Kingmax 206 clone. I dropped the 70mm pulley down to a 1 3/4 I think and now I can get it to go quite slow. I pondered the reducer but its anywhere from 125-145, I may save that for when I get a post-bed where I'll need slow for tight turns. I think the torque is fine for what I do, I can always hand wheel helper it.

If you are going from a clutch to a servo I don't think you'll be unhappy. I have seen the digital servos out there and youtube videos on how to turn them down more but they are 160+ on ebay so I went with the pulley change on my analog.

What about the ENDURO motors? I read that some members modified them to slow down the starting speed.

Seems there are motors with even 1400W power and they have mentioned the amount of torque in their descriptions.

Congrats on the Consew! Nice machine, a real Work Horse!

Thought I'd chime in, as I am going through same thing, trying to decide if I should get Servo Motor to replace my first Servo that I bought new and it was a bad one. It was a Reliable 3000 Sew Quiet, and it quit shortly after buying it. I know it is unusual, based on what I have read that other buyers of the same motor have written. But anyhow, it happened!

So, I found this one:

New Nick O Sew NKS 5500 110V Servo Motor Best Quality | eBay

I don't know how it compares to what else you are looking at, but looks to be 3/4 HP.

Let us know what you decide and how you like the motor you end up with. It's a hard choice to make and I agree, can be confusing.

Good luck!

I think I am getting that Nickosew myself for my post-bed I have on order from them, I have talked to Nick and he has a nice setup. I am not sure on the service yet as this is the first time working with them but they have a huge presence so I doubt they wouldn't support things. That said the NKS 5500 is an analog and I am guessing its like my Consew analog servo and doesn't give the bump control with the pedal I think you can get with a digital servo. Be interested to hear people who have both a digital and a analog servo on the differences.

A 70mm motor pulley is about 3 inches in diameter. This will drive the machine at a very high rate of speed. You will probably end up setting the rotary switch to the lowest setting, just to maintain control.

I have 50mm (~ 2") pulleys on all of my servo motors.

Wiz, i thought the speed dial only changes the max speed and has no other affect when starting and at low speed. But you have mentioned that it does reduce torque at startup and low speed. Is that correct? I understand the low startup torque I did not realise that the changing of max speed also degraded startup.

Yes it does lose torque at slower speeds, but not too badly on a typical straight stitch or walking foot machine. The heavier the load on the machine, the more pronounced the effect. If you only sew into medium temper leather, lower torque won't be a problem. You would notice it if you have a #24 needle and are sewing with #207 bonded thread, into 3/8 inch of water hardened veg-tan.

This type of application is where a smaller motor pulley (or speed reducer) comes in handy. It multiplies the available punching power, at the expense of top end speed. Replacing a 3" pulley with a 2" pulley increases the slow speed punching power by 1/3rd. You probably wouldn't even notice the 33% loss of available top speed (~ 2200 rather than 3450). I don't see most leather crafters sewing at 36+ stitches per second. Now, upholsters are a whole nuther story!

Gregg,

I have really been studying servo motor vs. clutch motors and although the cost is somewhere between $105-$150-ish, I want to make a good choice and not buy a motor that will quit on me long before it should, like my servo motor did.

So, can you please tell me what exactly the "S" means? Is that for "Switch" or for something else?

You seem to be the only Dealer offering this particular servo motor with an "S" on the end of the model number.

Do I really need to have the illuminated switch? Does it make the machine run better somehow?

I have found other motors that have either a similar number, similar look, or both... such as:

NKS-5500 (Nick-O Sew) Great Ebay Feedback, & They will sell to you over phone too.

FESM-550 http://www.zamirsew.net DC Motor, 3/4 HP

FESM-550N (Allbrands) I have purchased from them in the past, Very Satisfied.

I'd be happy with a clutch motor too, but still considering a servo again, reading what people have to say who owned them or who have owned them.

Please advise, if you can. Much appreciated.

Thanks so much.

The entire concept of the 500GR is that you don't need a speed reducer...so much for that I guess. BTW...speed reducers work great even with standard cluch motors, and give great low end torque and great low end speed control.

And yes, the Family FESM-550S ( "S" is the one with the external, illuminated switch) is a fantastic motor. I'm quite sure this is the one Wiz is talking about.
