Abstract

A DC permanent-magnet (PM) linear oscillating motor/controller system is discussed. The device described uses a novel manufacturing technique that results in a high force-density device. The mechanism of static force production and the effects of airgap leakage flux on the force are treated theoretically. Emphasis is on the exact determination of electromagnetic fields and forces for the resulting magnetic circuit. The analysis leads to these parameters and ultimately to the dynamic performance of these devices. The construction and initial tests for a PM linear oscillator motor and its controller have been carried out. The motor and its design and power electronics are discussed
