Study On Moving Coil Linear Permanent Manget Oscillatory Actuator

Moving Coil Linear Permanent Magnet Oscillatory Actuator (alias 'MCLPMOA' ) is widely applied in aeroplane , spaceflight apparatuses,automobile,computer HD,medical treatment machines ,air compressor more and more. As the servo system or driving source of the linear motion. Besides the characteristic of the motor style, The subject of this thesis is to study on MCLPMOA and the major works in this thesis are summarized as follows:1) Several basic types of Linear Oscillatory Actuator(LOA) as well as their basic configuration and performance principle are introduced.Analysis of the static characteristic of each type of LOA: moving coil LOA, moving core LOA, moving magnet LOA by Finite Element Method, besides applied situations of each style.2) Introduction of motor structure and some question on design. Determination of the static thrust characteristics of MCLPMOA by software MAXWELL 2D of Ansoft.3 ) Realization of dynamic simulation of MCLPMOA by Ansoft software Transient, Mathcad and experiments. Introduction detailed of the frequence changes effect on dynamic characteristic , obtained of stroke vs.frequence curve.
