Abstract
An actuator has a first stator with four first poles, a second stator with four second poles aligned with the four first poles, a permanent magnet between the first stator and the second stator, four armatures positioned at terminal ends of the aligned four first poles and four second poles, and coils 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 to selectively alter air gap sizes associated with the four armatures.
