Re: QS 3000w midmotor

Made a 3 hour trip today with the 72150 set at 250battamps and 450 phaseamps this at 58 volts.
The motor runs strong and with no overheating, i am very happy with the motor :D
Tested also foc and set it at 150amps, now with a 6 to 1 reduction it can run at 90km/u :o

Very nice, was planning pretty much the same thing.

BTW are you using something stronger than a 420 Chain?

Re: QS 3000w midmotor

QS 3000 vs D 3000 lol Thats another good example that Watt numbers say nothing about the size. See it more like a series number or just a product name :) This motor likely can do 3 to 4 times the power it was rated for, maybe even real continuous with good cooling. Regarding the belt drive i also t...

Re: QS 3000w midmotor

Ok, thanks! :D I will get one with a chain sprocket. Could you post a pic of the axle interface? I wonder how easy it will be to eventually replace the sprocket or get a selection of sizes. Did they have 219 chain sprockets? You best email to qs they make the axle like you want for me they make it ...

Re: QS 3000w midmotor

i am running the motor now for a few months with a sabvoton 72150 unlocked at 58 volts on my derbi senda.
Settings are 200 batteryamps 450 faseamps, we make hard drives in the woods for 3 hours every week with no problem so far :D
