This is a burned Losmandy G11 Gemini goto motor during my repair. The original electrolitic burn for a balancing problem. At first must be removed the encoder with a de-solder station. |
 |
Inside the motor encoder. It's important to handle with care the encoder plastic ring, that must be removed from the motor shaft. |
 |
The motor opened. It's important to pay attention removing the motor back plate, it's easy to damage the brush. |
 |
I replaced the damaged electrolitic with a same value tantal and glued on the rotor with a cyanoacrylate glue. |
 |
The tantal condensators should be all of the same size to minimize unbalancing of the rotor. It's not a simple task, but work great! |
