Greetings, a little help please. I'm trying to get a 48v 1800w BLDC motor running (MY1020). It came with the controller and pedal throttle from eBay, usual crap gokart sort.
Now, I've hooked it up to a 56v (57v charged) battery. The caps in the controller look rated to 63v I can't tell what the MOSFETs will take though. The MOSFETs don't seem to have popped, with no shorts to ground on the phases.
I can see the 5v signal on the throttle and the varying voltage on the throttle signal wire. The source voltage is showing at a few locations on the wiring harness.
The controller is switched on but I get no reaction from the motor. I haven't been able to read any output on the phase wires, but not sure the right way to do that.
Would the 48v controller have an over-voltage protection? It mentions under-voltage, but not over.
The PCB does have pins for different voltage configurations, not sure how I'd activate them, there is 5v across each pin pair. It wasn't sold as a variable voltage controller.
What troubleshooting steps should I undertake to try and diagnose the issue? TIA
