Hoverboard wheel are 350 Watt brushless hub motors. That's the same type of motor used in electric bikes and scooters. I figured what the heck, let's see if this thing will chooch. I bought a couple of cheap brushless motor drivers (QS-909 JYQD_V7.3) from amazon and ebay. Sure enough the motor moves, if you get the connections right.
There's a couple of things to watch out for.
First off, there is no heat sink on the mosfets. BE FREEKIN CAREFUL there! the body of the Low side mosfets are grounded, and the body of the High side mosfets are connected to 36V DC. So if you put a heat sink on both, you'll short the power source, POOF goes the fuse if you're lucky! Spark goes the battery if you aren't!
Problem 2: there isn't any documentation for the motor controller IC:
JY01
B636G001DG3
Best possible circuit trace I could make:
 |
| Traces on the front of motor controller. |
B
 |
| Back of board. NOTE: the image is mirrored, as if looking through the front of the board. |
Both
 |
| ALL traces drawn on the front of the board. |
Mystery pin: The second pin on the top right of the IC is tied to ground with a 10k resistor.
I have no idea what that pin does.
Leave me a comment if you find this helpful or can help solve the "Mystery of the mystery pin"

Thank you this helps alot but mine doesn't have the hall sensors will it still work im planing on making a e scooter.
ReplyDeleteSo how did you know how to connect wires from motor to controller. (Color wise)
