The speed control on the back is simply a variable resistance potentiometer, the same thing that controls the volume on older amplifiers. The output current to the motor is supplied by the printed circuit board in the bottom of the unit. This allows gradual increases in speed to avoid over-torquing the motor on speedup. Even the poshy-posh-posh mixers do this.
At least it still works. The most common problem is the cheap plastic drive gears that strip out with a mild cookie dough, this jams the beaters together and requires burial-at-dumpster.
SOURCE: Sunbeam Mixmaster is smoking from the motor.
I wouldn't turn it on again , if the switch is smoking then for all practical purpose;s the brush;s are nearly shot as well. I would look around the good will thrift shops or a Salvation Army Store you ;ll find a nice one there for less than a repair bill. You never know what you will find there. Have fun hunting.. DFD please rate me. Tku

OK, this may not be a solution, but might help you get there.
The speed control is NOT a potentiometer, it is a mechanical governer, and may be out of adjustment, or one of two components in the speed control mechanism has failed. The following is a test/ adjustment procedure.
During this procedure you will not be fiddling with electrical components (No risk of shock) You will be making adjustments with the motor running.
In the centre of the speed finder dial is a chrome cap. This can be *carefully* pried out. Be gentle, it's easy to chip the phenolic resin plastic.
Behind this cap is a nut around a threaded part with a screwdriver slot. Using a spanner and screwdriver to stop the centre part turning, loosen the nut some.
Turn the speed finder dial to 1. Plug the motor in and switch on. Whilst restraining the outer nut with a spanner, turn the central screw. From memory, it needs to be turned clockwise, that is, screwed inwards. The motor should respond by slowing down. Should you get no speed change, try turning the screw the other way some.
If you get a speed change, continue turning the screw in that direction until the motor stops. Now screw the other way until the motor just starts again.
This is the lowest speed and corresponds to 1 on the dial. Check the speed finder dial is still pointing to the 1 position. Lock the adjustment screw by restraining the central part, and turning the nut clockwise with the spanner until tight. Try turning the dial to see that the speed changes smoothly throughout the range. You may need to tweak the adjustment a little to get things just right.
Once you're happy with the speed control refit the chrome button, and you're done.
If you could get no speed change, one of two components under the speed finder dial has indeed failed.
Now you will need to determine just what the machine is worth to you. A motor specialist should be able to diagnose which part has failed. However, new parts will not physically fit and modifications will be needed. This could prove costly. If you know an inveterate tinkerer, you're costs could be substantially lowered.
Best of Luck.

G'day tandjcox842, did you get an answer to your question? If not, and you'd like to offload your mixmaster, I may be intersted. I've got one that works well but is missing parts. Regardz, Perry.
SOURCE: How do you remove the
Remove the end cap. It has 3 legs which are hooked UNDER the inside rim of the outer speed dial ring.
These legs look like a one piece plastic part as if it belongs to the outer ring, but it does not.
The end cap legs can be bent inwards, i.e. away from under the speed ring,
Make sure you have good light, so you can see how the legs move.
With a flat screwdriver (fairly wide) bend back (twist the screwdriver gentle) all three to evaluate how strong they are and get a feel.
That also help loosening them.
I recommend to bend back one at a time and put small shims where the screwdriver goes.
While I was able to do it without, it with shims it will be easier to keep the legs inward.
Once you get two legs to come up from under the ring, you can get the entire end cap out.
Had to do this to fix the tilt mechanism. There was an inner nut that had came off the holding bracket. I suspect vibration made it come off , so I put some nail enamel on it after fixing.
The speed ring screws etc. are all accessible once you have the end cap off.
To get to the actual speed control knob, just unscrew the next little part, you'll see and it becomes obvious how to get at the rest.
