The HALL sensor is a switching/current-sensitive sensor for determining the rotor position of BLDC (brushless) and PM motors. It generates precise signals to the controller to synchronise the phases, ensuring smooth starting, stable low speed operation and better torque control.
Key benefits
- Precise rotor positioning for better take-off and low-speed control.
- Stability and reliability – high quality switching even under challenging conditions.
- Wide compatibility – fits most e-bikes, scooters, Talaria/Sur-Ron and other BLDC motors (depending on model).
Specifications
- Type: HALL-effect position sensor
- Output: digital (open collector/model)
- Power supply: usually 5 V DC (check your controller/motor schematic)
- Wiring Output: VCC / GND / Signal (according to your motor wiring diagram)
- Quantity per pack: 1 pc.
Compatibility
- BLDC/PM motors with HALL sensors: e-bike, e-scooter, e-moto, Sur-Ron/Talaria (specific version depending on the motor).
- Controllers: most controllers supporting HALL inputs (5 V supply).
Installation and notes
- Switch off the power and disconnect the battery before changing.
- Observe polarity (VCC/GND/Signal); errors can damage the sensor.
- Install according to the manufacturer’s position (air gap to the rotor magnets), keeping clean of metal dust.
- After replacement, follow the auto-learn/angle procedure for the controller, if provided.
FAQ
Will this sensor fit my engine?
If the engine uses 5 V HALL sensors and the mechanical location/shape matches, yes. We recommend checking the model specification or writing to us.
How many sensors does a motor need?
Most BLDCs use 3 pcs. HALL (for A/B/C phase position). This product has 1 piece (for replacement).
