Tribology in Linear Electric Motor with Plate Mover

This paper deals with tribological systems of a linear electric motor for high-frequency motion and high acceleration, intended for the creation of an acoustic wave of the thermoacoustic conversion system. The main originality of this structure resides in the linear guidance (based on pressure screws acting on springs) used for the plate mover. Given the high acceleration and speed, it was impossible to use traditional mechanical guidance processes (V-guide rail and Cam-roller guide). The plate mover is made up of a translator of sandwiched magnets between two stationary stators. This plate mover is in magnetic balance between the two stationary stators through a controlled friction device.
