If you search for "solar vent" on this site, you find this. "$9 solar motor (I purchased mine online from Sundance Solar - part # 700-60062-00)." Its from a very old thread, but I think its the one I used when mine needed rebuilding...

 

Thanks - this is very helpful. I couldn't find Sundance Solar motor, but found something very similar.

 

Will you post the part/source? We have two not working.

Mark,

Yes, I will, but not right away. I haven't received the part yet, and I want to make sure it actually fits and works with the solar cell. I'll post an update once I have installed the motor and it's spinning again.

Mark,

I received the motor and installed it, the fan is spinning again. The motor is a 12 V DC RF-500TB-12560 model with brushes. If you type in the model number, you'll find multiple sites offering the motor - I got mine from Amazon. On the whole, I am not entirely pleased with it, though: it seems a bit underpowered, slightly too small, and the shaft is just a little too short to attach the fan blades securely (unless I glue them). At best, it's a temporary solution. I have been looking for a slightly heavier motor that fits more tightly, but have not found anything yet.

I used a RF-500TB-14415 to replace a failed 700-60062-00 that I could no longer source. Worked well, and was about $7 on amazon.
