We changed all our machines at work a couple of years back.Fantastic and well worth doing.Not noticed a loss of power.Jack servo motor not sure if 3/4 hp or 1 hp.Went for needle positioner, I've set mine up so the needle stops just on the way up, tap of the heal and needle rises, great for stoping and turning on corners.Other machines set to stop with needle up which I don't like as much.Tapping my foot I can do one stitch at a time.I did extend the length of the motor arm and the foot pedal arm for a bit of extra control.

Learned on servos and will always use one, clutch motors are noisy and damn near dangerous! lol

We have two "Family" servo motors on our pfaffs and I bought a consew servo motor for our long arm. Alot of bad reviews on that consew motor and I can see why after having it in a short period of time. Far too fast even after putting a different pulley on. The electronic RPM gauge is nice, but it starts at like 500 rpms and goes up around 3500. Came with a needle positioning sensor but thats for down the road.

So I pulled the trigger on the "Family servo, 550s" should be here tomorrow, hope I like it!

I have Servos on both my machines, never going back. I am now planning to rig one to my drill press.

Got the servo motor today and have it installed, love the way I can go slow now and just chunk along if I want. No more 0 to 60 in a half second! Will wait till I run some carpet thru it before I declare full success...

I switched all of my motors to Family servo motors a few years back and I'm so glad that I did. I absolutely love them

I'm a big fan of servo motors since I switched. A nicely worn in clutch motor can be nice to use but servos are so much more predictable in my optinion. I don't have the needle position option on mine but they're so controllable you can stop with the needle down (or up) every time I've found.

i swapped the clutch on my Seiko & it has made such a difference, haven’t been brave enough to play with the settings yet tho.
