How the braided copper wire is soldered into a carbon brush? 2

[pcusa]

I needs to fix the motor of an automatic window in my 93 Camry. Somehow during the process, I broke the subtle carbon brush and need to replace them. I could not find discount carbon brush as a repair part in autoparts stores. If someone knows, please tip me. I then try using the carbon stick from a used C-size battery and manufacturing it into the shape I need. There came the problem, I could not solder the braided copper wire onto the carbon graphite easily. I wonder how this is done on commercial parts? Is there a special machine for such job? Thank you.

Wires are not soldered to carbon brushes. A hole is drilled into the brush larger than the braided wire. It is than packed and tamped with carbon dust and sealed with a sealing compound. Sorry I can help you any further

Try taking the motor to a motor rewind shop. They should be able to get you the correct brush.

However, for this recent of a car it would be cheaper to go to a junkyard and buy a used motor.

One thing I have done in the past with difficult to find brushes is to go to a motor shop which does DC motors. They have a lot of different size brushes in their stock. Find one close to yours and use fine emory paper to sand it to the size where it will fit in the brush sleeve in the motor. If the brush is too long you can cut it off and shape the end to conform to the commutator. There are different hardnesses in brushes and you can ask the motor people for help.
