just wanted to share email i got from AMY who works for MXUS:
Hello Jack ,
I am Amy , may I know are you customers of our company ?
Thanks for your note of our new super powerful motor . It is new upgrades of V2 .
V3 motor and cover cannot put into the V2, because V3 stator is bent , and the axle of V3 is bigger .
If you want to know the difference, the link writes perfectly.
"The 3K-Turbo, upgrades the axle from 17mm to 20mm diameter on the wire side with a larger bearing to squeeze in 5.26mm² phase wires (76% increase in cross-sectional area): Larger phase wires reduces the resistance and increases the efficiency of the power delivery to the motor. In addition, the 3K-Turbo adds a spare set of hall & temp wires for double-redundancy more reliability. The larger phase wires are particularly beneficial for the 3T and 4T windings where the cross-sectional area of the winding very close to the same 5.26mm²."
OK , now would you like one sample , one sample total is 239$ including shipping to your company.
If you like it ,let me know .By the way ,if you add my Skype : rollyyou
That would be great .
Best regards
Amy
