Hi, I recently ordered a 2000W 48V DC Brushless Motor & Controller Kit from Vevor.
Motor model : MY1020D
Controller model : BY15WF02-A
The kit went together fairly easily, all the wires went together by color and it went in reverse, researched it might be a hall/phase combo, messed around a bit and switched the hall sensors on the motor and switched the phase wire combination to the following:
PHASE
Motor | Controller
B | Y
G | G
Y | B
HALL
Motor | Controller
B | B
G | Y
Y | G
and that was it, I was scooting along on my homemade EBike. Yay. For about 30 minutes. Then whenever I gave the system throttle, it would make a grinding type sound and come to a halt. I immediately stopped and felt the controller, hot to the touch, motor pretty warm to the touch not as hot as the controller. I proceeded to pedal home to try to figure out what went wrong.
Assuming that the controller was toast, and wanting an upgraded controller anyway, I ordered a KunRay 48V-96V 80A 3000W controller. I THINK the model number is : KRBLC0 1014, not entirely sure.
I wired it up according to the store's suggestion at:
PHASE
Motor | Controller
Y | Y
B | G
G | B
HALL
Motor | Controller
B | Y
B | Y
G | G
I then connected the selfstudy wire to itself and the motor started spinning in the wrong direction, according to the advice from the company, I unplugged it and plugged it back in and it started spinning the correct direction. I let it run for 10-20 seconds, also according to the company, then unplugged it (you guessed it, according to the company). I then gave it some throttle WITHOUT the tire connected via chain and it seemed to run fairly smooth, sometimes jumping backwards then smooth forwards depending on how it felt. But once I connected the tire to the motor, all heck seemed to break loose. It will sit still with no throttle, cool. Give it some low throttle, the tire jumps around a bit then goes, gives it slightly more throttle, HORRIBLE grinding sound and tire comes to a halt. Manually pedal the tire to make sure its not mechanical, all seems good. I am pretty sure I tried out all of the phase/hall combos (forgot to mark a few off when going through them) and all of the combinations have the exact same results.
I then read that it might be a motor issue itself, which I assumed would be fine as it wasn't sweltering hot as the controller was. So I cracked that bad boy open and with my vast superior knowledge (i have no clue what i was looking for) I came to the conclusion that it didn't look melted. so that's good right?
And this is where I am at right now. A complete and total loss as to what the issue could be. I don't have another motor to test this controller on at the moment, but I have a voltmeter and know how to follow directions. Any and all advice is appreciated.
