Yeah, I've been meaning to update that. I'll do it now. I actually got that info from the lehner site. I guess there must be different shaft options?

EDIT: Updated the 1940's with a 4mm shaft...

Yeah, it caught me off guard since the 1950 was a 4mm. Oh well, Mike straightened me out. :005:

Seriously, your motor calculations and everything is awesome - an excellent resource. Thanks.

The 1950 is 5mm. 1940 is 4mm, as well as the other 19 series motors (4mm).

Brain, for the Wye vs Delta configuration, I'm not exactly sure which, but one of them increases the KV by 1.73, not decreases. I just don't know which way does what lol...

Nevermind...Wye decreases KV (by reducing voltage by 1.73). When the motor is used as an alternator, Wye boosts voltage by 1.73, while current is reduced by 1.73. So in a motor configuration, its logical that voltage is reduced by 1.73. So I guess this means using wye allows the use of more voltage, since KV will end up being the same...

This is pretty useful.
