Abstract :
A novel transverse-flux moving-magnet linear oscillatory actuator (TMLOA) for a compressor is proposed and analyzed, which features a unique configuration composed of usual laminated stators and moving-magnet mover. It not only offers low manufacturing cost and great dynamic characteristics, but also provides high thrust force density for its transverse flux path. The magnetic field and thrust force are analyzed by three-dimensional finite-element model. The proposed model is also used for studying effects of the axial dimensions variation on the thrust force and stroke, and then the selection of axial parameters is obtained with reference to the amplitude and smoothness of thrust force. Finally, the measurements of a prototype validate the predicted results. It shows the proposed TMLOA is very suitable for linear reciprocating motion drive applications such as compressors and pumps.
