There are magnets inside the handles of electric bicycles, usually neodymium arc segmented magnets, with the shape shown in the figure below. Some netizens asked if the magnetic steel inside the handles of electric bicycles/tricycles affects speed? Let's talk about this issue.

Electric tricycle bicycle handle speed controller arc strong magnet

The magnet in the electric bicycle/tricycle handle is usually used to sense the position and speed of the motor to help control the speed and action of the motor, the presence of the magnetic steel (magnet) itself does not directly affect the speed of the electric vehicle, but its role in the system has an important impact on the performance and speed of the electric vehicle.

The speed of the electric vehicle is mainly determined by the output of the motor and the power supply of the battery. The neodymium arc magnets in the rotary handle helps to sense the position and speed of the motor, and the output power of the motor can be adjusted by cooperating with the electronic control system. This means that through the operation of the handle, you can control the acceleration and deceleration of the electric vehicle, but the magnetic steel itself does not directly affect the speed.

It is worth noting that if the magnet in the handle is damaged or malfunctioning, it may cause problems with the control system of the electric vehicle, which in turn affects the adjustment and operation of the speed. Therefore, if you find that the speed of the electric vehicle cannot be adjusted by the handle, you may need to check and repair the magnetic steel or other related components in the handle.

Electric bicycle handle magnetic steel (magnet) type;

There are two common types of electric vehicle rotating magnetic steel, one is a single long arc, the magnetic induction intensity of the magnet surface, in different parts, the size will be different, the magnetic induction surface of the Hall element, away from the magnetic steel slightly distance, when the specific position of the magnetic steel changes, the magnetic induction intensity applied to the Hall element will also change. The voltage output of the Hall element will change.

The other is to install a small magnet on both sides of a certain arc of the small ring, so that the Hall element is between two small magnets, different parts between the two small magnets, the magnetic induction intensity will be different, the electric vehicle rotating handle rotation, the magnetic induction intensity applied to the Hall element is also changing, the principle is equivalent to an arc magnet above, However, because the magnetic induction intensity between the two small magnets is affected by many factors such as the deformation of the material in the installation position, the overall linearity is not as good as the single arc small magnet.

Conclusion:

The magnet inside the electric vehicle handle itself does not directly affect speed, but it plays an important role in the control system of the electric vehicle, helping to regulate the output of the motor, thereby affecting speed and power.
