Good motor to me (my first build) but it miss some power to me. Now i project to buy a mac or a little dd motor but i'm very curious about the potential of this xf19r. Knowing what is the best controller for example

40-43 battery amps I would say is the limit, you can bump up the voltage higher, to 72v, so you will get about 3000w.

Which motor?
1boris said:The motor was very cheap 104 usd and 67 usd for shipping to Norway

Been running the xf19's as my new favorites. I am a builder in Boston area.
I run them on 48 volt KT controller 12 mosfet, I cut the cable at the axle exit and replace it with
Grin Cable with the 12g. phase and 7 control wires.
I did that because they easily take 2200 watt bursts and seem to run better and not hot hot cable to deal with.
The small section from end of axle to windings also stays warm at worst.
I stopped doing BBSHD builds in favor of these. A nice light K2 or Jamis frame and they pop wheelies and fly.
So far I got 6 MTB builds out there mostly with hunters, one guy who runs trails.
KT setting C1 I think, raise it up to 90 and that opens the gate.
I do cap the current to about 1600 watts for customers....
Do they rate them as the same wheel speed (in same size wheel) at that voltage? If so, there isn't an RPM difference.Kajman said:Guys, anyone have idea of rpm difference between 36v and 48v version? Nice motor anyway.
Did you buy the stock XF19r with no special winding? Does report speed at while coasting? Is there a temperature sensor? How are they still doing?Thought I'd add my 2 cents.
