Castle 1717

[rabosi]

I think Himalaya is right. In post #11 Patrick show a caliper measurement for the 2025 to be 53.67mm. I did a rough comparison measurement from the photo on page one and it seems like the diameter for the 1717 is around 45mm (+/- 1 maybe?).

That measurement is on the end cap, the o.d. of the fins will be quite a bit larger. The 1717 (1.7 diameter rotor) will need to be at least .2 inches larger or about 5mm than a 15 series (1.5 diameter rotor), and more yet if they pack more/larger windings in there.

Say 1515，the first 15 is the can dia.(w/o fins), not rotor dia. for instance the Neu 15 series has a dia. of 1.53"(39mm). the latter 15 is the rotor magnetic length.

Correct. The endcap is about 0.2mm smaller than the can. With fins added the can gets 1.8mm larger, thats exactly 55.6mm shown on Castle website. It's def a 2025.
I was trying to figure out if my KB45 watercooling jackets fit the 1717 and found this on CC website.
