The electric bicycle turns and turns the motor. It doesn't move. What's the matter?
2, turn the negative electrode broken (probably negative contact bad), will drive, turn off the key, and then re open the key, the controller will protect, and no response, easy to judge turn into burning.3, the controller is broken, can not normally output current and voltage, replace the controller.
The turning handle of an electric car has 3 lead wires: the power supply (+5V), the ground wire, and the signal line (linear continuous change signal). There are two kinds of electric switches used in electric vehicles, the photoelectric switch and the hall switch. The electric cars which use the hall switch at present make up the majority. The magnitude of the output voltage depends on the magnetic field strength around the hall element. Rotating the handle changes the magnetic field intensity around the hall element and changes the output voltage of the hall switch
The electric bicycle turns and turns the motor. It doesn't move1, bad line contact, it is likely to turn the line of a place of high voltage caused by a string.
