Anybody Know How To Adjust The Clutch On A Clutch Motor?

[LoveToLearn]

Im looking at the pedal travel and when I push the pedal down I can see something that looks like a disk brake rotor and a brake shoe. There is an adjustment screw that looks like it sets the travel of this shoe. On the other side of the rotor looks like some kind of wheel that engages by means of friction with the brake rotor thing. What is this and what is the proper adjustment? Also are there any replacement parts for these clutch motors? This one is a Consew motor 1/3hp 1750 rpm. My goal is to have my machine up and running by the end of the week so I can start learning how to sew.

Thanks

On that style of motor, the flywheel is attached to the rotar. It has a smooth surface and is rotating as long as the motor is on. The plate that moves back and forth with the lever has cork on both sides. The small pad closest to the pulley is the brake pad. The adjustment moves this pad closer to the brake side of the clutch. There's no ideal adjustment, but rather operator preference. The only requirement is that when you remove your foot from the pedal, the machine should stop. You "apply "the brake by heeling back. If you want more control, move the brake pad (via the adjustment screw) farther away, more responsive, move it closer. Be sure and leave a gap big enough so you have a neutral position you can hold with your foot. This allows you move your hand wheel freely. Your final adjustment should be the pitman rod, the two part rod system that adjusts the pedal height. Leave it low enough so when you heel back, it presses the brake against the brake pad. Make sure to tighten the locknut on the adjustment bolt. Have fun!

I'd recommend setting it to about 1/2 inch of free motion on the floor pedal before the clutch starts to engage. That should give you enough time to anticipate the action of the clutch and learn to feather it in. With a steady toe, you should be able to feather it down to about 1 stitch per second, or so. I do that on my clutch equipped sewing machines with no trouble.

You can move the swivel cup and linkage all the way out to the last hole on the motor lever to get more travel and better slow speed control.

I have an old Singer chainstitch machine and was wondering if anyone knew how to adjust the speed of my motor so I am unable to go super fast.  Just beggining to learn and it's really hard to keep it at a steady slow pace just using my foot.

Many people have an option to change the motors pulley to the smallest diameter they can get for that motor shaft.

This likely requires a v-belt change also, and is probably the cheapest and best you can do with that setup.

Though speed is definitely noticeable its not crawlin slow by any stretch.  

Another very good addition is to lengthen that typical clutch motors lever, the foot pedal link is connected to. 

So these clutch types do not have ability to  slow the actual motor down. Moving from that a photo of that machine area could help in descriptions. 

In other considerations a servo motor may be an option, and this is a good time to ask one or call one of the dealers that are posting in this machine area. 

 

Have a good day

Aside from the previous replies about installing a smaller motor pulley, adding more free movement with the motor's clutch/brake adjuster screw, and/or lengthening the motor's control arm, you could disassemble the right end of the motor and smear a little grease on the clutch pad. This should let it slip a little, allowing you better control before the clutch fully engages.
