Atwood Motors
 

...so does anyone know if the atwood motor is the same as last year's one, now that the specs are up? (in terms of performance?)

Atwood,Chiaphua,CIM...whatever!
 

Antonio,

I could kick myself for not remembering the exact #'s, but I'll get it for tomorrow. We, just for the heck of it, put it on a tachometer/strobe and found that both motors were VERY much slower than last year's motors. We used the same strobe last year, so I know that that isn't the problem. I want to say that it is less than 4000 rpms but I might be mistaken. I'm sure that before I can post our actual #'s some one will have some data of their own.

BTW both motors were within 4-7 rpms of each other--which is pretty good. Also there was the anticipated 175 rpm difference between foward and reverse.

The out put shaft is different for the one from last years. its a 1/2 inch shaft with a keyway.

are you sure its 1/2"? I was playing with one yesterday, and it sure didnt look 1/2"....

This site has good info on the atwoods we got: http://kevin.jpl.nasa.gov/first/chiaphua.pdf

Is this spec sheet for this year's motors?

I'm not really sure, I found it on one of the other forums I was browsing through. This might not be this year's, but it has charts and stuff which can be pretty useful for other help.

well, I guess it doesn't matter that much since we can use last year's Chiaphua motor which means they must be the same

It has a very nice hex coupler that easily converts it to a 5/8" axle, as does the Bosch drill motor
