Add a tip to the wiki page about correctly connecting motor hall sensors #281

Closed ForcefulBlow closed 2 years ago

ForcefulBlow commented 2 years ago

Hello!

Recently I've been building a 2WD electric scooter, and I got quite frustrated when I tried to find a proper combination of phase/hall wires. It wasn't obvious if I connected hall/phase wires right in torque mode, because wheels were spinning with extreme speed no matter how lightly you touch the throttle (which is absolutely correct as it is a torque mode), and it was pretty jerky and sometimes it vibrated etc.

However, in sine wave mode with voltage control it was extremely easy to understand if hall sensors were connected correctly.

Hi,

True, people could be using variant ADC first, as it's using FOC-voltage mode, to make sure the inputs and wheels are connected in the right way and working. Hovercar variant/torque mode can be misleading without load, that's why I had added a video in the troubleshooting section of hovercar variant to show how braking behavior can look weird without load.

Regards,

Candas

Added an additional tip for troubleshooting in Firmware compatibility section of the wiki @EFeru what do you think about that ?
