Notice the rotor strength of my "Certified Plus" rotor that came with my original. Yep, 1700... Also notice that the sensor angles are better on the V2, mind you timing needs to be adjusted because it is too high to start off with on the new motor. Or I think it is, I'll find out...




Here are the readings I get from my milliohm meter (Instek GOM-804), using the pt-100 sensor as well to account for the temperature offset to 25°C.

Slot Machine V1 Certified Plus
AB: 55.3mΩ
AC: 55.2mΩ
BC: 55.2mΩ

Slot Machine V2 Race Spec
AB: 55.2mΩ
AC: 55.0mΩ
BC: 55.2mΩ

And here are the inductance readings from a cheap lcr meter, checked with no rotor in the can.
Slot Machine V1
AB: 118.4µH
AC: 116.9µH
BC: 118.0µH

Slot Machine V2
AB: 120.1µH
AC: 119.5µH
BC: 119.4µH

What does all this mean???
Fantom Racing champions the idea that if you can find a stator that has the same IR and slightly more inductance, that stator would be the better stator. Well my V2 I just received has lower IR than my Certified and higher inductance, so on paper the V2 is a better motor. I'll do some load testing and dyno pulls on them later.
