Pfaff 545 industrial sewing machine overview and video

[gavingear]

Hello all, I just completed a Consew servo motor install on my Pfaff 545 walking foot industrial sewing machine, so I thought I'd take a few minutes to explain how this machine works including a description of the speed reducer, and the servo motor.

Pfaff 545 sewing machine overview:

- Made in Germany (top quality)

- Walking foot with needle feed (feet are clamped on material and needle pierced when feed takes place)

- High lift feet (about 9/16")

- Large capacity top loader bobbin

- Reverse and stitch length adjustment

- All metal lower shaft/gear drive (newer pfaff 1245 has rubber belt that can require replacement)

A couple key additions on this machine:

- Speed reducer (about 3:1) - 3x the effective motor torque, and 1/3 the top speed

- Electronic servo motor (Consew CSM 550) - Spins only when you are sewing, silent otherwise, brake, adjustable top speed, precise speed control and start/stop

You won't go wrong with that bad boy! Wonderful machine and the servo definitely kicks it up a notch!! I was sewing a suede patch on the elbow of a 40 year old fringe coat tonight on my 29K60. I was sewing it a stitch at a time using the flywheel because of the nature of the coat and patch. I kept saying to myself when the heck are you gonna pop for $150 and put a servo on this treadle machine??? It sure would have come in handy tonight and made the job a lot easier.

I have a 545 pfaff machine also. A few years ago the knee lift, attached to the underside of the table, broke and the parts were lost in a move of my upholstery shop

I can't fix it because I don't know what the missing parts looked like.

After watching your video on youtube, it appears you have the same type of knee lift

Would be able to post some pictures of the lift so that I can have someone make them for me?

I would rather buy a new knee lift, but can't find one

I have two brackets (that a horizontal bar runs through) that attach to the underside of the table. There is a lever with a wheel on it that makes contact with the lever on the underside of the sewing machine

What is missing is maybe another bracket between the lever w/wheel and the front bracket

Thank you for any help

Good video. I got a lot out of it. Thanks.

I'm thinking of getting a CSM 550 for my Pfaff 545 since they can be found for about 130 shipped in some places. Is it hard to install a reduction drive for these? Where can I find one?

JoysShop,

I have a Pfaff 1245 which replaced the 545. I believe pfaff upgraded the knee lift for the type you have just like Adler did on their 267-373. I do not have a parts list for the 545 but I know someone does. That said, you could then find out what parts you need for the foot lift. I will check and see if I can get you a parts breakdown on that set up.

Hi gavingear, nice set up and video. You should put a smaller belt from the motor to the speed reducer so you can utilize your belt tightening capabilities. Steve

Looks really nice. Godd setup. Good machine!!!!

Joyshop,

I have searched for and finally found a parts manual for the 545 pfaff. It shows the complete illustration for the knee lift assembly on page 96. I can fax it to you so you can determine which parts you are missing since this shows all the pfaff part numbers. It took me some time to find it and I hope it will help you. The parts manual is 117 pages long!!!

Just thought I'd mention that I have what people have been asking for.A DC motor with

a built-in reducer,which mounts like all the other motors but eliminates the lining up & drilling holes required when mounting a reducer & motor separately and for less $$ too.
