Alien Power Systems Hall Sensors with VESC6

I have two alien power 80mm motors running in FOC.

I have hooked the sensors up and checked that i can rotate the motor slowly and get 5v on the different hall sensors between the +5V and phase hall sensors, but I've read I should get voltage from hall sensor to ground, can I not operate in this way??

It WILL NOT detect the motor hall sensors in BLDC or FOC mode, and i'm pretty sure i've hooked upeverything right, since i do get output on the sensors when probed with a volt meter.

what the heck am i doing wrong!?

 

The motors have no temp sensor, so that wire is skipped over. I hooked Red to +5V Ground to Black, and the three phase hall sensors to the remaining 3 wires closest to the ground pin.

 

So frustrated right now!  I want the extra low end torque because i ride offroad, and i want all my power to be able to start well on rocky hills smoothly. I have tons of power, but startup is still a little... meh

Can you show a drawing and pictures of how you connected everything?

Absolutely.  So the motor does spin when doing the detection, it spins very slowly, but it does not complete even a single rotation. I've tried different amperages (up to 50A current)

So, in this image The wiring is connected to the motor just as seen. I put the old connector next to the new one in the same orientation as the wiring has been connected. so as follows:

Old Connector   |      New Connector

Red                  ->     Green

BLANK            ->   Orange  No Connection (Motor has no temp sensor)

Blue            ->      Yellow

Yellow             ->      White

Green              ->      Red

Black             ->       Black

In my opinion red wire should be connected to V+ and black to GND, the rest is halls. If your motor spins and doesn't detect hall it's likely that hall power supply is connected  incorrectly.

It looks correct as far as I can tell. I will try to make a terminal command that tests the hall sensors to see if something seems to be wrong.

I wish I could maybe visualise the output in the logging. I can hook up my scope and take readings if that helps too

Are you sure the halls are working? I had an APS motor where the hall sensor wires broke so many times that I switched to external hall sensors.

I also had to ask APS for the wiring diagram for my motor. For mine it was: yellow - positive, red - negative, black white blue - sensor signals, green - temp. I had the 3000w 63mm motor.

I've emailed them for a response. wow if my cabling is like your's, my halls are definitely hooked up wrong, and probably blown. Ugh.  I hope not, but we'll see.
