Control system for e.g. refrigerator- or air conditioning linear compressor, varies voltage applied in accordance with adjusted stroke reference value

摘要

A unit regulating the maximum stroke (21), compares the maximum stroke value with the current stroke (25). It alters the value of a stored stroke reference value (22), for output. Voltage applied to the compressor motor is controlled (23) in accordance with the new stroke reference value. An Independent claim is included for the corresponding method.
