Abstract

A voice-coil-type LOA consists of the NdFeB permanent magnets with high specific energy as the stator, a coil-wrapped nonmagnetic hollow rectangular structure, and an iron core as a pathway for magnetic flux. When applying a voice-coil-type LOA to the control system, we have to obtain the control parameters and circuit parameters, such as mass, coil inductance, coil resistance, thrust voltage & stroke, frequency & stroke and so on. Therefore, these parameter were determined from the analytical and experimental method.
