The hall induction magnetic ring is often used in the BLDCM and some fixed speed motors. It is also called hall induction magnetic pole in the industry of BLDCM, because the hall induction magnetic ring is generally a multipole magnetic ring. Its working principle is to rely on the induction of multiple magnetic poles and Hall elements of the magnetic ring, so as to test the speed and efficiency of the motor, and can provide the information according to the hall induction magnetic ring To control the operation of the motor.
Generally, the hall induction magnetic ring does not need too strong magnetism. As long as there are multiple poles arranged and can provide the magnetic pole signal to the hall element, the hall element can get the signal to work normally. Therefore, the hall induction ring is mostly the same-sex ferrite ring.
Our company has many specifications of motor multipole ring magnet. Please let us know the specifications of magnet for our quotation and provide samples close to the size.
