Servo Motor Pulley size for Juki 1541S with speed reducer

[SachaWLT]

Hi Folks. Just joined Leatherworker.net although I've gleaned a huge amount of info from this resource.

 I'm looking to upgrade from a clutch motor to an 800 watt servo motor (looking at the Enduro Pro SM650-1) for my Juki 1541S. I have a 3/6/9" speed reducer mounted and I'm mainly sewing light leather, canvas and cordura nylon for bags. what size pulley with the new motor would one recommend for my set up?

Thanks for any insight.

The smallest that you can find which will fit on the shaft..which will probably be a 40mm or a 45mm ..

If you want to sew as slow as possible then always fit the smallest you can, as mike said. With the reducer that you already have fitted, however, even a 3" should still be fine.

I agree the reducer is going to have plenty power and the servo itself will be able to stitch pretty slow when and if you want.

The ones I have had all came with 90mm or others I had a choice for smaller, see how your belt setup works as is, first.

Save your money for the moment, And Welcome to the show! 

Good day there

Thanks for the advice, ya'll.

The motor comes with a 2" pulley so I'll probably just go with that for now.  I really appreciate the help.

2" should be fine, I wouldn't bother trying to get a smaller one 'cos it won't be much smaller!

BTW better to use a toothed belt with the smaller pulleys, the teeth allow the belt to conform to the smaller curve better, belt lasts longer, tensions are more even etc.
