Just see a know the question is about electric vehicle (bicycle) turn handle magnet, the netizen asked electric vehicle turn handle with what magnet? How does its magnetic force change? See also did not introduce very detailed, the following permanent magnet supplier courage to tell you about it.
What kind of magnet does electric bicycle turn handle use?
Xiao Fu has been in contact with several customers used in electric vehicle speed control turn, they use NdFeb arc magnets (curved magnet), proofing is used N35 performance, this can withstand 80 degrees of temperature. Most electric vehicle magnets are based on NdFeb material, after all, there are certain requirements for magnetic force.

What is the change of magnetic force of rotating magnetic steel magnet?
At present, most of the handlebars are Hall handlebars. The output voltage of Hall handlebars depends on the strength of the magnetic field around Hall. Turning the handle changes the strength of the magnetic field around the Hall element and thus changes the output voltage of the Hall handle.
Guess you also want to know if the magnetic force of the magnet will demagnetize?
The magnetic steel will slowly demagnetize due to the motor heating and other factors, but because the internal Hall element is highly sensitive, it will not affect the use of the motor in general. Unless the motor overload and other factors cause the motor to produce a lot of heat in a short time and cannot timely heat dissipation, resulting in irreversible serious demagnetizing phenomenon of magnetic steel, and finally lead to the motor unable to operate and permanent stop, the magnetic steel can continue to be used after replacement.
Because customers use different specifications of the transfer magnetic steel, need to quote or find samples, welcome to contact courage magnet( High-temperature resistant NdFeB rotary handle magnet can be customized for you ).
