摘要：
We have developed a high-performance moving-magnet rotary actuator for very low-profile magnetic disk drives. A small moving magnet and efficient low-profile magnetic circuit construction give high acceleration and reduce power consumption to 50% that of moving coil actuators. The arrangement of the coils and yokes increases the design flexibility. The actuator does, however, suffer from a magnetic bias force and large inductance.
