An annular linear alternator of 100 W class were fabricated. The electrical output of 100 W was obtained for a design operating condition with regular stroke at the highest operating speed. In the alternator testing the magnet plunger was directly connected to a motor-driven moving mechanism. The linear alternator is composed of a plunger with permanent-magnet ring, power coil, inner yoke and outer yoke. We studied on the operating characteristics of three stage magnet rings and two poles linear alternators. An installed force sensor could give mechanical power.
