Inspired by the RC builds here, I got a TURNIGY AERODRIVE SK3 – 6374-149KV outrunner from HobbyKing for my BladeZ electric stand-up scooter. I installed internal halls and went through all 36 combinations for the hall and phase wires. However I can't find a really low current draw when testing, the lowest I got was over 11A under no load (which compared to what I read here seems really high). I got the motor to turn smoothly when there is no load, but when I ride on the scooter it doesn't turn anymore (or turns really slowly when I do a running start). Here are additional details about the build, wondering if anyone can spot if there's something wrong with my setup:
batteries: 48V Turnigy lipos, 15C
controller: 48V conhis motor controller rated for 1kW (I also have a 72V huatong but haven't wired that yet for the scooter)
motor: Turnigy Aerodrive SK3, rated for 12S, 149KV, 2kW+. I think it has 14 magnets, 12 "gaps" on the windings.
halls: SS413A, installed internally, 120 degrees apart
rider: 147lbs
My hypothesis is that the halls may be shot, I had to cram them in really tight spaces. But I wouldn't know if the symptoms above (high no-load current, wouldn't turn when I'm riding on it) support this. And if so, what would be my options? Would going with external halls solve this? Or is it the controller that's the constraint? Thanks for any help!
