A free piston gas Compressor, a method to avoid the overshoot of the portion of alternation of a linear motor and a Controller for linear motor

摘要

A free piston gas Compressor comprises a Cylinder, a piston which can rotate inside the Cylinder and a linear Electric motor coupled to the piston is derivable in Alternative that has at least one Winding excitation.Is a measure of the switching time of the piston, any change in the switching time is detected and the Power input to the excitation Winding is regulated in response to any changes detected in the switching time.
