Abstract :
This paper is associated with the manufacture of a transverse flux linear motor (TFLM) and the characteristic of the thrust force and the maximum displacement of the mover in linear motor. The thrust force of this calculation is in good agreement with experiments. We utilized a new design for household electric applications that the volume of a linear motor reduced by 3/4. In this paper, we examine the initial displacement of piston for linear actuator and the reaction force of sustained body for a constant spring coefficient and damping coefficient under several current rates in linear motor. Thus, we calculate with FN3D and ANSYS and experiment the thrust force of the linear actuator with applied current, 0, 500, 1000, and 2000 [ampere turns, AT]. We used the experiment with several types of alternating current and the phase difference between the peak value of applied current and the maximum displacement of the mover of the linear actuator is changed with applied current frequency
