A Hall sensor that stays fixed on the tester is no longer switching properly. This may be caused by an internal failure, a power supply issue, or a fault in the signal return line.

⛔️🛴 A hidden motor issue many people mistake for a battery or controller problem 👀

🔍 Cause: displaced magnets inside the motor.
When magnets shift out of place, the magnetic field becomes misaligned. That can cause electrical noise, loss of torque, and poor performance under load.

✅ That’s why a motor may spin fine in the air, but fail when actually ridden.

🧲 Your motor is losing power… and you don’t even know why ⚠️
Magnets work because their internal domains are perfectly aligned 🔄
But when heat builds up 🔥, that alignment starts breaking down…
Push it too far and you hit the Curie point → magnetism is gone.
No strength. No torque. Just damage.
🔥 The result?
Your motor struggles, overheats… and can burn the windings.
⚠️ What’s killing your magnets:
📈 Overcurrent → too much load = too much heat
👊 Hard impacts → internal structure gets disturbed
🧲 External magnetic fields → mess with alignment
🌧️ Corrosion → slowly destroys the material
⛔️ End result:
Weak magnets = weak motor = expensive repair
