I need help again
 

I ask for help on here and got what I needed.

This time I may not be so lucky.

I have a short arm quilting machine. My motor is getting hot. I can only do 3 rows before I have to stop and let it cool down. I have the information off the motor, just can't find one on google.

Even thought my machine is a Singer 911 comercial the motor is much smaller than the clutch type motor that mounts on a comercial sewing table. It is belt driven and mounted on the back side of the machine. It's a Groschop or Croschop. I couldn't tell what the first letter was. It's a 90 vdc, 1.09 amp, 70 watt, 3500 rpm.

Anyone have any idea where I might find one?

Thanks in advance for any help.

Maybe your belt is too tight making the motor work too hard. Can you adjust the belt to loosen it?

No in fact the belt is a little loose. Not enough for it to slip but I can hold the wheel and move the belt by hand.

Does it need some grease?

If it’s been a while since you serviced it, you might be getting enough additional drag combined with a slow sewing speed to make the motor hot. I think I would do a full service (clean out lint, apply oil and grease where needed) on the machine to make sure it’s turning freely before I did anything with the motor.

Lint buildup between the feeddog base and the needle plate can cause gradual loss of performance, but I don’t know if your machine even has feeddogs if it’s being used for FMQ.


I’m not familiar with the Singer 911 machine, do you have a photo?

Singer 911

Googling Singer 911 comes up with this image. Motor should be powerful enough without over-heating:o.

Not sure I would put one of those motors on a sewing machine. Porchse 911s?

The only thing that creates heat on a sewing machine is friction. Whether it is lint, dust, or whatever, your motor is being forced to work too hard. That is why it gets hot. Please stop using it until you can clean it out or have someone do it for you. Right now you have a very dirty motor, if you keep using it, you will be buying a new motor. Much cheaper to have it cleaned.

We've done searches from ISMACS to Google to, well several others and have yet to come up with any Singer 911.

Could you post a pick of your ailing machine and recheck the model number?

I agree with the poster above that says a good cleaning and lubing should take care of it.

Man, if you dropped one of those on top of me, I'd overheat too! My floor might also not take it.

Most motors can be serviced, belts are the most common cause of too much heat and I agree, a good general service might just take care of the problem you know about and some potentially impending ones.
