Hall sensor PCBs used in 3-wheel / 4-wheel electric-vehicle hub motors.

Hall elements” / “Hall sensor PCB” for EV hub motors are small PCBs that contain 3 (or sometimes 5) Hall sensors plus the cable/connector used by motor controllers to detect rotor position. They’re commonly used in brushless DC (BLDC) hub motors for 2/3/4-wheel scooters, tricycles, and small electric vehicles. Supplier listings often label commonly-used replacements with codes like Y3461, G3141, Y3141, 461, 3141 — these are vendor part IDs rather than a single manufacturer IC.  Typical featur...
