I want to use this thread to post up information on these motors in one location for others to reference if they are using them.
First the most important, the phase / hall wiring combinations
If you are using a Lyen Controller on one that uses the same color combinations as his the wiring is as follows (same as original version)
Phase:
Motor -> Controller
B->B
G->G
Y->Y
Hall connector 1:
Motor -> Controller
R->R
B->B
B->B
G->G
Y->Y
Hall connector 2:
Motor -> Controller
Orange -> Red
Black -> Black
Grey -> Yellow
Brown -> Green
White -> Blue
kV measured the same as the previous version 9.3kV
Inductance appears to be slightly higher than the previous version and measured it at 145uH vs the previous versions 120uH
Axles are 16x1.5mm thread pitch
Continuous power handling is rated at 5000W, I have not tried to torture test one yet, however my original version survived lots of abuse at 12,000W and still looks new on the inside and the covers are sealed.
Will it FIT! without lube or stretching
The axles on the V2 are different from the V1
The flange of the V2 motor is centered, not off center like the V1 is (but corrected for with a custom axle to center it). The axle ends are 40mm long from the shoulder and have 40mm of thread. This means that the V2 Axle is 40mm+137mm+40mm for a total of 217mm long with the 137mm shoulder to shoulder portion centered along with the flange.
That's always the question with something packing this much awesome so here are some measurements I've made with pictures to hopefully help you figure out if it will fit on your frame.
I made on my makeshift test stand that has a dropout width of 149mm.
First up, 2 shots of my testing setup
Close up
Freewheel side placed against the drop out, there is some small variance in where the axles shoulder flat is between motors, about +- 1mm judging from what I've seen.
Wire exit and disc brake side. These are of course all sans disc brake so please take into account it's size and the bolts that hold it on when trying to figure out if it will fit.
Measured gap from axle shoulder flat to the dropout
This is the reason I supply the freewheel side washer with the motors. It's not always needed, but differences in freewheels and small variances in the axle position necessitate it. This is a random 16th Dicta brand freewheel I happened to have laying around with the washer in place. I did not tighten the freewheel at all, so it can go down further than pictured here. This motor has the axle shoulder perfectly flush with the freewheel threads.
Washer thickness used for demonstration.
So what is the theoretical minimum dropout size that we can fit one of these motors into?
Dropout distance of 149mm - disc brake side gap of 12mm = axle shoulder to shoulder width of 137mm. I believe the actual spec is 135mm they are machined to, so the difference is just measurement error, but I'll err to the side of being bigger at 137mm.
Add to this the freewheel + washer most likely needed to prevent binding and you end up at 140mm (a thinner washer could be utilized in many cases, I went with a size that I knew would work for all variances that I have encountered in axle offset to prevent binding).
So if you were to run this without a disc brake, you could theoretically run this in a drop out as small as 140mm, but I can't guarantee that due to variances in frame design and small differences between motors. This is why the official spec is 145mm minimum with work, but it can be made to fit smaller dropouts if you have some skill/creativity.
Next up, how to take your motor cover off and add a temperature sensor.
I'll add more info as I gather it.
