What do the three wires of the throttle handle represent?
1 Answers
The throttle handle has three wires: one signal wire and two power wires (+5V positive and negative). The three wires are red, black, and green. If the red and green wires are short-circuited, the vehicle will move directly. Alternatively, if the black wire among the three wires comes off while the other two remain connected, the vehicle will also move directly. However, some controllers are designed to prevent runaway and will only operate when there is resistance. The principle of the electric vehicle throttle handle is based on the Hall throttle handle principle: Inside the throttle handle, there is a linear Hall sensor that detects the magnitude of the magnetic field. The three wires are connected to the three pins of the Hall sensor, typically colored red, black, and green, representing the positive, negative, and signal terminals, respectively. The throttle handle also contains a magnet. When the throttle handle is turned, the magnet rotates accordingly. The Hall sensor detects the magnetic signal and sends a signal to the controller, thereby controlling the motor speed. If the throttle handle wires are disconnected and the positive and signal wires are short-circuited, it is equivalent to the motor running at maximum speed, causing it to spin continuously. Disconnecting the wires will stop the motor.
