Piston's displacement damping method for linear electrodynamic engine, involves detecting induced current in induction coils by displacement of piston, and applying amplified damping current to coils with respect to induced current

摘要

The method involves detecting an induced current in induction coils (11, 21) by displacement of a piston, where the piston moves in contrary direction parallel to an axis of a linear electrodynamic engine based on an alternative movement. Frequency of the alternative movement is equal to a resonance frequency of an electromotor unit. An amplified damping current (I'nd) is applied to the induction coils with respect to the induced current. An independent claim is also included for a supplying circuit of an induction coil of a linear electrodynamic engine for implementing a damping method.
