Abstract :
This paper deals with the efficiency and the iron loss of linear oscillatory actuator (LOA) under two driving methods. The two driving methods are sinusoidal-current and rectangular-voltage drives. The efficiency and iron loss of the LOA are 79% and 2.84 W/kg under the sinusoidal current drive with an exciting current of 1 A and frequency of 37.1 Hz.
