Set of 3 HALL Magnetic Motor Sensors for Bicycle, Scooter, or Electric Scooter – Compatible A3144, 41F, SS41F

Set of 3 HALL sensors for electric bicycle, scooter, and e-scooter motors – ideal for rotor position control and proper motor operation. Compatible with most electric vehicles: electric bike, electric scooter, e-scooter, hoverboard and more.

• Compatible with models: A3144E, OH3144, Y3144, SS441A, 41F, OH41, SH41, SS41F, S41, SS49E, OH49E, 49E
• Detects bipolar magnetic fields – responds to the presence of a magnet in both directions
• 3 pins: +5V, GND, and signal
• Connects to a 5-wire connector: 2 for power, 3 for the signals of the 3 sensors

Usage and Diagnosis

If the electric motor does not start, vibrates, makes unusual noises, or “stalls” at startup, one of the HALL sensors may be faulty.

To check, move a magnet above the sensor: the output voltage should vary between 0V and 3.2V. If no variation is observed, the sensor is likely defective and should be replaced.

Note: Other possible causes of motor malfunction:

• Uninsulated or broken wires – especially where the cable exits the motor
• Defective controller
• Power supply or connectivity issues
