WTB: BLDC motor controller 72V

Post by Bigpie »

Years ago I converted a trials bike, it's somewhere in the projects section, anyway I sold it on as I wasn't using it and the new owner is looking for a motor controller now. Max voltage of 83V and 200a peak, 110a continuous was the claim on the controller. It's a 20s battery.

If you / they are willing to go diy,

It will run a few different control firmwares.

Otherwise there are some large vesc controllers out there that should do.

Is an older Kelly any use? https://endless-sphere.com/sphere/threa ... 00.121580/

That might be of interest, might be massive overkill for the little motor.

Wouldn't be that massive - the Kelly is 150A battery / 300A phase and the motor has some headroom for a voltage upgrade down the line.
It's likely bulkier though.
