  • Brushless DC motor actuator having remote commutation sensing apparatus
    Publication number: 20070252541
    Abstract: A brushless DC motor and Hall Effect commutation sensors are mounted on a common circuit board, and ferromagnetic elements partially embedded in the motor stator in proximity to the periphery of the rotor magnetically couple the rotor magnet to the Hall Effect sensors. Preferably, the ferromagnetic elements are embedded in the stator adjacent the radial periphery of the rotor magnet. Alternately, the ferromagnetic elements can be embedded in the stator adjacent the axial periphery of the rotor magnet.
