What is the function of the Hall element in electric vehicles? This question is very general. There are many places where Hall is used in electric vehicles, and the Hall elements used are also different. \r\n The first is the role of the Hall element in the electric vehicle speed control knob: the angle of rotation of the knob converts the changing magnetic field intensity of the magnet into a changing digital voltage that is provided to the controller through the Hall element to adjust the electric vehicle. speed purpose. \r\n The second is the role of the Hall element in the electric vehicle motor: the main function of the Hall element in the electric vehicle motor is to change the phase current direction and is used to replace the motor brush, so the motor using the Hall element It must be a brushless motor. \r\n Again, it is the function of the Hall element in the power-off brake lever of the electric vehicle: the Hall element of the power-off brake lever converts the change in the magnetic field intensity of the magnet caused by the brake lever displacement into a digital voltage and provides it to the controller. The motor is powered off and the braking unit is started. \r\n Some electric vehicles are equipped with a power assist control system. The function of this Hall element is to change the magnetic field strength of the magnet by turning the pedal and convert it into a digital voltage output, which is provided to the controller to achieve the power assist function. \r\n Finally, some electric vehicles are equipped with a mileage speedometer. This Hall element counts the number of revolutions of the wheels of the electric vehicle, and then directly displays the mileage or driving speed through the calculation of the instrument. It is used For speed testing. \r\nI hope it can help you, give me the best one.
