Re: window motor spec sheet confusion
Here is something that adds to the confusion: The spec says it has a pitch diameter of 20.2184mm. This equates to .796 in. So if you do the standard calc for gears (NT/ PD = DP) you get: 9 / .796 = 11.3 Diametral Pitch! Huh!
So, what is going on here. I guess we should ignore the 20.2184 number?
