good point luke
All we need to connect two motors to one throttle is a Y-Cable if we have two torque mode throttle controllers. Should work flawless.
The only thing that must be unsprung weight is the sprocket on the drive axle. The motor could be mounted on the swing arm near the pivot so it's not unsprung.
Anyway, back on topic: Measured motor weight, my scale shows 5.32 kg
including the free 14T
that my motor came with.
Just ask for one if you order your motor there, they charged me nothing for that.
The inner dia of the sprocket : 14.22 mm
Key thickness: ~3mm ; width: 3.95 mm , length: 10mm (same as sprocket length/thickness)
About KV: I measured 146Hz @ 44.4V. With 6 pole pairs this must be spinning at 1460rpm. Around 32.9 KV
About Inductance: I measured 311 µH
Cogging is so hard... i never had a motor that has so much cogging
The silver finish is really crappy.I'll wash it of with turpentine
There is a slot that looks like made for a 20-26-4 shaft seal ring. But it seems like the shaft surface was not polished at that place. Something we should do by ourselves before inserting a seal.
