Abstract:
An actuator includes a first stator with four first poles and a second stator with four second poles aligned with the four first poles. A permanent magnet is attached to the first stator and the second stator. Four moving armatures are positioned at terminal ends of the four first poles and the four second poles. Coils are wrapped around the first stator and the second stator. A controller selectively applies current to the coils to migrate flux created by the permanent magnet through selective poles of the first stator and the second stator and thereby alter the size of air gaps associated with the four moving armatures.
