ABSTRACT:
A closed-loop system is implemented during startup for accurately determining the magnet offset between a set of magnets and a set of windings of a brushless DC motor. The determined magnetic offset value is used to align a position sensor to the actual angular distance between the windings and the magnets. The alignment of the position sensor setting is in turn used to provide a commutation current that allows the motor to operate at maximum efficiency.
