Stator and Carriage for a Piezoelectric Liner Motor

A piezoelectric linear motor apparatus and method is provided. The apparatus comprises a carriage configured to be actuated and a stator configured to actuate the carriage. The stator comprises a meander line structure and a gear teeth structure, coupled to the top of the meander line structure and a contact layer underneath the carriage. Furthermore, the meander line structure comprises a series of bimorph actuators laid linearly in the meander line structure. Each pair of neighboring bimorph actuators being linked with a corresponding connector on both sides of top and bottom. The meander line structure also comprises an odd series of connectors and an even series of connectors, interleaved with each individual connector, applied with phase-splitter's alternating current (AC) power to deform the bimorph actuators for generating traveling wave. The gear teeth structure is configured to transport traveling wave from the meander line structure to the carriage.
