英文摘要：

Aiming at the low thrust force of a transverse-flux double-stator moving magnet linear oscillatory motor （LOA） , the working principle was analyzed. The dynamic model of the motor was established and the dynamic factors were investigated. The effect of main structure parameters on motor thrust force performance were investigated based on 3D finite element method （FEM） , such as gap thickness, length of permanent magnet （PM）, PM thickness, the location of the rotor, inner stator thickness, etc. Based on this, the parameters were optimized and a transverse-flux LOA with high thrust force for a refrigeration compressor was designed. The results show that the motion follows the law of sine arid the structure parameters such as the length of PM have great effect on performance. By optimal design, the thrust force can reach 700 N, which meets the application requirement of high force.
