Abstract: This paper deals with the efficiency characteristics of a moving-magnet-type linear oscillatory actuator (LOA) for compressor by using a novel measuring method. In this measurement, another linear motor is used as the load instead of compressor. The relationship between efficiency and the phase of the load current is investegated. Maximum efficiency of the LOA reaches to 87% at the output power of 61 W.
