I run a clone of this motor at 3-7Kw all day without trouble @ 80v. Gets hot but 3mm phase wires are fine.
Realize OT, but anyone have a comparison for the "real world" **max torque** between these two?The Toecutter said:torque for the Leafbike motors

ZeroEm said:I'm sure it depends on the frame. On my trike 2019 7T Leafmotor 3mm phase wires, run a 7 speed cassette without spreading forks. Going to try to force an 8 speed in.
I peddle a lot and don't notice any drag from the motor. Of late set my speed limit at 28.5 mph/46 kph and pulls 20 amps @ 74V by Grinfineon 40A controller, have my max amps set at 36a (why it"s my battery continuous discharge current, 10sec burst is 80a) until my temp sensor is hooked up. I have 5 ml of FF and never even stressed this motor. My ridding style averaging 10w/K, steepest hill top it at 20 mph.
The Toecutter said:Also, does anyone have figures for the hysteresis drag torque and eddy current drag torque for the Leafbike motors? I could not find these figures published anywhere, but it would be nice to calculate how much wattage I'll need to overcome the cogging losses when riding with the drive system turned off, and to also be able to compare other motors for which these figures are published.

if not, you could use the hubmotor outside the wheel, in the drivetrain (like rassy did, or one of the various other versions), or separately chained to the wheel (so not in the pedal drivetrain), and have a freewheel (or clutch) between the motor and the wheel. thus the drag when not powered would be essentially nothing.
you'd also end up with stronger wheels this way, since the hub would be smaller and the spokes longer and more able to be laced "correctly" than with the large hubmotor in the wheel.
spinningmagnets said:I was told at Interbike that it costs less than $10 per motor, so I am shocked and saddened that more hubs aren't the thinnest lams by default, without some special order and a huge MOQ
