What Causes a Hall Sensor Fault in Tricycles?
2 Answers
Generally, electric tricycles with voice prompts will announce a Hall sensor fault. Symptoms of a faulty Hall sensor in an electric vehicle motor include the motor not turning, turning weakly, or making abnormal noises. If the Hall sensor in the motor experiences a short circuit, the vehicle may not stop when intended. Below is relevant information: Specific symptoms: If the Hall sensor in the motor has an open circuit, after stopping, turning the throttle may not make the vehicle move, or it may move intermittently, indicating a faulty Hall sensor in the electric vehicle motor. Solution: If a Hall sensor fault occurs, it is recommended to open the seat cushion, disconnect the circuit breaker of the controller, wait for ten seconds, then reconnect and reset it, and try riding again. If this does not resolve the issue, please seek assistance from a professional mechanic for repairs.
I've been delivering goods with a tricycle for ten years and have encountered issues with Hall sensors several times. Mainly, the bumpy roads cause the sensors to become unstable, leading to poor contact over time. Additionally, during rainy days, moisture seeps in, causing internal short circuits or oxidation and rust. If you frequently carry heavy loads, the wire connections can loosen, preventing current flow. Once, while delivering in the mountains, the Hall sensor suddenly failed, and I had to push the cart for dozens of miles before finding a repair shop. The mechanic said the Hall sensor near the motor was clogged with mud. I recommend regularly checking if the wire connectors are secure, especially before the rainy season, and taking preventive measures.
