    What is the temperature resistance of magnets used in brushless motors?

    The brushless motor adopts electronic commutation, the coil does not move, and the magnetic pole rotates. Brushless motors use a set of electronic equipment to sense the position of permanent magnet poles through Hall elements. Based on this perception, electronic circuits are used to switch the ...
