Brushless DC motor and magnetic compensation method thereof

A magnetic compensation method for a brushless DC motor is mainly to provide a magnetic element disposed on the PCB or adjacent to the Hall sensor in the motor to compensate the magnetic bias of the Hall sensor of the motor resulting from the ambient unnecessary magnetic influence on the Hall sensor...

More Information
Summary:A magnetic compensation method for a brushless DC motor is mainly to provide a magnetic element disposed on the PCB or adjacent to the Hall sensor in the motor to compensate the magnetic bias of the Hall sensor of the motor resulting from the ambient unnecessary magnetic influence on the Hall sensor; therefore, it can keep the Hall sensor output a regular voltage at each magnetic pole phase.
