Hello i've got an inconventional BLDC motor and wondering if i can use a conventional driver board.
see my photos. 3 lines for the coils, 3 for the feedback signals, and 2 more (+ and -) to power some kinda circuit who-knows-what. The really weird thing is, the connector has nine leads in it. I checked it with a loupe.

 

Is there a name plate on the motor, or do you know what it came out of?

 

It may be BLDC operated, it could also be controlled in a AC 3ph fashion.
It appears to have a tire on the outer edge for a direct drive traction motor.
Max.

yeah its one of those scooter wheels with the integrated hub motor. no identifying markings, just a serial # that didn't get any hits on google. the guy i bought it from said it runs on 36v. it's very likely from one of those rent-a-scooters like bird or lime, and i figure it runs off of a 10s li-ion battery pack. those things all run off the 18650 batteries.

 

I'd be very tempted to cut the connector off unless you have the socket.

The PCB is a great help...
Red wire is +5V power for the Hall sensors I would think.
Black = 0V
Yellow = Hall sensor for phase A
Green = Hall sensor for phase B
Blue = Hall sensor for phase C

Then there will be 3 wires for the motor coils.
It may take a bit of experimenting to get the A, B and C motor phases correct. but it should be pretty straight forward to try out.
Do you have the driver board for it?

I may have misunderstood the original post, but took it that he wanted to try to use an ESC, instead of a hall sensor driver. If that's the case, couldn't the hall sensors just be ignored?

 

well no i don't have the stock board, the controller that i have is a generic board, it has three outputs, U, V, and W. it is one of those "sensorless" controllers with no inputs for the hall sensors. IIRC, it syncs the phases by sensing the back emf. so yeah i'm assuming that it will work without using those signals.
what i dont get is that little blue board. i thought the hall sensors didn't need any 5 volts to operate.
i do have the 9-lead cable to mate with the connector, but i don't get why there are 9 leads.
check this photo. i figure that those black rectangular things are the sensors, but why do they have 3 wires?
thanx, mike

well AFAIK, these kind of scooter motors are all the BLDC type but i can't say for sure.

That would be a pair for supply voltage and one for the signal.
Max.

 

The Hall sensors need 0 and +5V to operate.

If you want to use a sensor-less driver, just leave the Hall board unconnected.
Don't remove it as it may be used with another driver board. I think low speed will need it.

ok then yeah i'll just leave those leads unconnected.
much obliged fellas
