Abstract: A method for monitoring a linear compressor is provided. The method includes determining a velocity dependent induced voltage in a driving coil of the linear compressor, extracting a higher order harmonic from the velocity dependent induced voltage, and establishing that a piston of the linear compressor is crashing if the higher order harmonic is greater than a reference value.
