I have a Bernina 707. I believe the motor just started on fire. It was humming loudly and smoking. Can I replace the motor? Are they available? Can someone rework the motor? Bonnie McCartney
Are you shure the armature or electric field of the motor is blowing out is it not only the interference suppression capacitor?
Your Bernina 707 can most likely be repaired. You can take it to a Bernina repair shop. Sometimes they can rob parts from donor machines. If you really like your Bernina and would like to keep it, it is probably worth checking out repair. Purchasing another machine of similar quality in good working condition could cost ~$300--in addition, you probably already have a lot of accessories for the machine which would work only on vintage Berninas made before ~1986. Search eBay and see what comes up for similar machines that have sold. Who knows, they may even be able to repair the motor... In my humble opinion, your 707 is a keeper if nothing else is wrong with it.
If you are very creative you can install a generic motor ~ $30 but you will have to create a bracket.
Yes
However you are likely looking at $300 plus not sure machine would be worth that expense if you need a motor I have one for sale

Yes you can have the motor replaced. You need to take to a certified repair center though.
I WOULDN'T BE SO ANXIOUS TO REPLACE THE MOTOR YET. MANY TIMES THE BELT WILL GET OUT OF ALIGNMENT AND CAUSE THE BELT TO SMELL BURNT AND THE NOISE WILL BE PRETTY LOUD. CHECK THE BELT AND WHILE IT IS ON SLOWLY TURN THE BELT WITH THE MOTOR (KEEP HANDS AWAY). THERE IS AN ADJUSTMENT FOR HOW MUCH PULL AND TO ALIGN THE BELT. IT IS EASY SO DON'T WORRY. NOW, TO GET TO THE BELT! LOOSEN THE OUTSIDE HANDLE ON THE WHEEL . LOOSEN THE SMALL SCREW AND CONTINUE TO UNSCREW THE HANDLE; REMOVE IT. NOW, LOOSEN THE INSIDE LUG AND TAKE OFF. REMOVE THE WHOLE HANDLE. THE BELT WILL FALL OFF. REPLACE THE BELT. REPLACE EVERYTHING. (BEFORE YOU START IT IS HELPFUL HOW MANY TIMES YOU TURN TO REMOVE). ONCE EVERYTHING IS REMOVED SLOWLY PUSH THE FOOT PEDAL. LOOSEN THE BELT ADJUST AND MOVE IT WHILE YOU PUSH ON THE FOOT PEDAL. IT WILL COME TO A POINT OF ITS FASTEST AND QUIETNESS REST. TIGHTEN THIS BOLT AND REPLACE EVERYTHING AND START SEWING.

Motors can be replaced easily and are not too difficult to find. However, give a look at the belt. If the hand wheel isn't allowing the belt to move but the motor is trying to force the belt to move it will cause the belt to burn and smell bad. Check the hand wheel to see if it is moving freely. Anyway, check this before you replace the motor. If you replace the belt it must be adjusted by a bolt that holds the motor tight. While the motor is running slow move the motor in and out and side to side. You will notice the speed of the motor change as you do this. The motor speed will be at it's highest when you will tighten the bolt.
