Abstract

A moving-coil-type linear oscillatory actuator(LOA) consists of the NdFeB permanent magnets with high specific energy as the stator. a coil-wrapped nonmagnetic hollow rectangular structure. LOA system have the push/pull effect caused by the unbalanced magnetic field. In order to eliminate the unbalanced thrust, we propose the control algorithm and construct the LOA driver. As a results, we obtain the balanced oscillating thrust.
