Hello, today I got my e-bikes 40amp controller and tried connecting it to a 1.4kw hub motor - this is to replace the 0.6kw motor on my scooter for a power-up. All the wire colours matched and it ran first time but I noticed the wiring got very hot, ie too hot to hold on to! This was after running at full power for more than about 10 seconds. Speed also seemed slow
To cut a long story short eventually I tried connecting the controller wires together that changes motor direction and the damn thing nearly flew out the vice, the wires are now luke warm and I NEED to try this on the scoot... but I checked the direction and now the brake will be on the other side.. probably can figure something out but can I get the motor running happy in the other direction by switching the power wires around?
Eventually I'd like to get another motor as a spare depending on how it performs as I think 1.4kw could be too powerful for my 26ah batteries. The motor I got came on a wheel that is a perfect match for the old one, don't know if I've been lucky or there is a common standard or how easy it is to fit a motor onto a wheel. Any tips from the pro-s here appreciated. If I manage to get it running will post the differences in performance obtained I have no idea what to expect
