Dear all.
I've bought a BLDC motor VEXTA AXHM-230K ( AXH series). I designed a driver board for it, the board is ok. But i don't know how to connect the wires of motor to the board. As same other BLDC, It has 8 wires, 2 wires for Vcc&GND for hall circuit, 3 wires hall feedback, 3 wires for winding, but i don't know exactly what wires. Do you know wiring diagram for this motor? please help me. I can't find it out on the internet. Please help me. Sorry because my english is not good. Thank you verry much.
You should be able to reverse engineer it if you have a double beam scope.
A low resistance across three will be the stator windings.
Connect a 1k resistor to each winding and join the ends of the resistors together to form a virtual neutral point, the scope will go to this neutral point and each winding.
If you back feed it while scoping each phase in turn and apply power to the hall circuit and check for coincidence between each hall and each of the generated phases.
