I am assuming that you are discussing a motor from a Swiss made older model Bernina machine using a phase controller such as the type 290 or YC-420. The motor description will say SEG 884...? If so, the motor brush holder's black plastic tab can be bent up (lifted up) to remove the old brush and bent back down to hold the brush in position.
Note: The tabs can only be bent 3 times before they break off.....

Bernina 807runs without the pedal and doesn't stop


I suspect it may have something to do with the foot control unit or the motor itself. There are usually some carbon brushes that wear and may need replacement, although I doubt this is your problem. Worn carbon brush symptoms are usually a jerky, sporadic power issue. Some of the older foot control units have a part (I believe it's a capacitor) that goes bad--in some cases can cause a fire. In some machines, that has been repaired but other machines out there still have the original equipment.

There is a "BerninaThirtySomethings" group on Yahoo that would be very helpful with questions you have about your machine. You will need a Yahoo account, request to be added to the group, then you will have access to all the files, previous conversations, as well as asking your own specific questions.

Oh, I just found this:

I have bernina 530-2 record and cant get it to start. nothing happens when I lift the knee control. Does this mean it needs a new motor?


Some of these old machines have carbon brushes in them. When it gets worn down from use and eventually fails to make contact, it will no longer work. The replacement carbon brush is relatively inexpensive ~$15.

Concerning 1970s 830 Bernina. There is no motor sound..nothing. Are the carbon brushes in the pedal?


The 830 models varied so I'm not sure. My machine looks like this:

Bernina 830 sewing machine feet pedal accessory box table instruction...

If you scroll over to the photo of the motor, there is a white plug which pulls out. Underneath, there is a screw. The carbon brush may be there. However, some 830s had the speed switch on the machine (right above the knee control) and others have it in the foot pedal.

I found the following information in my computer files that may be helpful: Bernina 830 Motor Brush Replacement

My machine is actually a Bernina 830 (mechanical 34 years old) I need to know how to get the housing off the motor so my hubby can replace the brushes

Re: sewng machine motor housing

DISASSEMBLY TO INSPECT OR CHANGE BERNINA 830 MOTOR BRUSHES:

Remove the big plastic cover piece on the bottom of the machine with the single screw in the center.

Remove the machine's end panel by removing the single silver screw from underneath the bottom middle of the side panel. Pull the bottom of the side panel out and down to remove it. It comes off easily.

Remove the two screws under the motor assembly (silver screws with black washers).

Swivel the motor assembly enough to remove the belt.
There is a another plastic panel on the motor assembly over the motor itself. Remove the two phillips head screws to remove this panel.

At this point you can see the commutator and inspect the "business" ends of the brushes. (In our case, one brush was almost gone and there was nothing left of the second brush except the spring!)

You can then slide the motor out of the housing. I pushed on the motor pulley and pulled on the other end of the motor with pliers. The motor comes out rather easily, but be careful not to disturb the wires any more than necessary.

With the motor exposed, unscrew the caps over the brushes and remove the brushes.

Our motor's commutator looks significantly worn and the motor may need to be replaced.

FWIW, if your machine hasn't been oiled for a long time, you should probably take time to do that. When the old oil solidifies, it sticks the moving parts together. Forcing the motor to try to run the machine can damage the machine. Use fresh good quality sewing machine oil or (I use) liquid Tri-Flow Synthetic Lube and apply a couple drops every place metal rubs on metal. (Wiggle the handwheel and watch where things move.) Do NOT oil belts, synthetic gears, cams.

I have a Bernina Sport and when I press the foot pedal only intermittently does power go to the machine. How do I correct this?


It could very well be the carbon brush. It is generally a piece of soft carbon (like pencil lead) with a spring on the end which applies pressure. When the carbon gets worn down, it does not make consistent contact. Depends on your machine model. I've replaced carbon brushes on the motor of an 830 Record, but I had to replace something in the foot control. Do not despair. The replacements can be found for ~ $12-15. Available multiple places. Just be sure they will fit your machine.

Bernina machine starts sewing anfmten stops or doesn't start at all.


Be sure that you regularly clean and oil your Bernina. If not oiled regularly, the old oil turns to varnish and actually freezes the parts. Some people believe something is wrong with the motor or foot control, when really it just needs some TLC to keep it running smoothly.

May be one of several issues--depends on the model Bernina. Could be a problem with the foot control. I had to replace a carbon brush in the foot control of my 930. (A new foot control could cost over $160!)

Or some machines (mostly older models, ie 830 Records) have carbon brushes on the motor that wear with age. Once they've worn down, they no longer make constant contact giving you the "intermittent" issue. I've replaced carbon brushes on some older Berninas--usually found somewhere around the motor (look for a screw or knob on the motor). You can buy replacements a lot of places. I've purchased them on eBay.

How to remove on/off knob and feed dog up/down knob on Bernina 1130 - do they just prise off and push back on?


Both of these knobs simply pull off.

On my 1030 (which has only the on/off knob), you can get your fingernails behind the edge and pull; it's not on very firmly.

Give the oiling a go. At the very worst, you'll have to take it to a technician to fix but you are unlikely to break anything but be mindful of the screws underneath when you retighten them - the nuts into which they screw are only held by thin plastic on the cover.

THE MOTOR USUALLY HAS A LARGE SCREW. WHEN YOU REMOVE THE SCREW THE CARBON BRUSHES WILL SHOW. THERE IS USUALLY TWO. YOU CAN TAKE THEM TO A LOCAL MOTOR SHOP TO GET NEW ONES.

How to remove end cover from bernina 830 record (handwheel end)


There is one screw on the bottom of the machine in the center of the handwheel end. Remove this screw fully. Then the cover should come off fairly easily. The top of the cover has two pins that slide up into the housing of the machine. So be careful not to break these while removing the cover. Also, the screw that goes in from the bottom is held tight by a metal washer that rests in a plastic channel on the cover. Be sure not to lose this washer. If you do, you will not be able to reattach the cover.
