my new consew 206RB-5 premier 550 variable speed servo motor-speed control

[wydfuqnopn]

Just bought this machine and love it. Would ultimately like a cowboy 105 too but could only afford one or the other. I bought it for the range of sewing it will do. I will be using it primarily for belts, purses, wallets, briefcases, etc. nothing really above 8-9 ounce leather. but occasionally for applications where I will appreciate its speed. I also bought the 50mm pulley for the motor from consew.

Here is my question that I will appreciate anything you can offer.

How slow can I get it down to?

can you recommend that I use a gear reducer or a larger pulley system underneath?

is there a "monster wheel" or something of the sort for the actual "head" that I can use in conjuction with the 50mm to accomplish a slower speed without having to use a gear reducer or larger pully system underneath?

Thank you in advance. im new to all this sewing stuff with a machine. Been doing it all with two needles and thread up until now.

 

Best regards,

steve

Steve, I have same motor on my Pfaff 1245. With original 75mm pulley it was little too fast for me. With 45mm pulley it is much better. Keep in mind I'm learning too, so it may not be a problem to someone with experience. To me - this one change is good enough, but I'm working on upholstery stuff. For small items like you mentioned I would probably think about reducer, but again, I think this is 95% experience and 5% motor reducer

Work with your current setup for a bit.  If it's slow enough for you, then your're good to go.  If you need more slow-speed control you can always add a speed reducer.

Simplest way is to find a large pulley to replace the handwheel, an 8" will give a significant speed reduction (I've done this on three of my machines). There have been a few posts about this method as well as lots about speed reducers.

I haven't actually installed the 50mm pully yet because I wanted to use it as it came before changing it so that I could recognize the difference. thank you for help

ok so I have seen the you tube video but I have talked to 3 different people who work for companied selling the machines and they all said that it would possibly harm the machine but they hadn't done it themselves so couldn't give me reasons why. I know there are plenty of manufacturers who make a larger wheel for their machines and works without damaging the unit. I actually bought a pulley before talking to them and decided to just do it the established method. My pulley didn't have any places for screw to go into the bore so returned it. Bye would like a bigger handwheel anyway. Thx for input

can you recommend where to buy one?

To give you a frame of reference here...

 

The 206RB series is an upholstery machine. The stock handwheel/pulley on the machine combined with a standard pulley on a motor allow the machine enough penetrating force yet still have plenty of top-end speed to run through yards and yards of upholstery fabrics in a production environment.

For leather, different ballgame.

Nobody selling these machines is going to recommend throwing an iron reducer wheel in the mix and increasing the torque to a machine past what it was engineered for. It arguably can reduce the life expectancy of the machine if you are placing a greater amount of torque to it than was originally intended.

However, people do it all the time. These machines are made to last for years, sewing 40+ hours a week. They can handle a hobby level of abuse.

 

You have some choices:

Use the stock 550w motor with the smallest pulley you can fit on it (typically 45mm - 50mm) (cheap)

and/or

Add a larger pulley in place of the stock handwheel. You want one with a 3L belt profile (still cheap)

and/or

Add a speed reducer pulley under the table (about $150 - $200)

and/or

Add a high-end motor with good low speed control ($250 - $1000)

See this thread, pretty much this whole conversation is covered:

And if you want to take it to the next level -

large wheel + speed reducer, gives me 1 stitch every 2.5 secs! Yes, I know, it's a bit extreme, but........

Seriously, a 2" on the motor and a 6 - 8" on the head unit (as in R8R's link) should give you the control you want.

man that is beautiful right there. every 2.5 seconds that's almost enough time to pour a cup of coffee..in the kitchen. guys I thank you. this forum is incredible. so glad I joined. wish I would have before I bought my machine but hey, whaddayado.
