This paper describes the permanent magnet single-winding LOA in terms of its structure, static thrust characteristics, frequency characteristics, temperature characteristics, and other features as shown in experiment results, and also describes the LOAs high output based on magnetic field analysis. We applied structural analysis to design a high-power version of a single-winding LOA that is structurally simple enough to be used in artificial heart actuators.We compared calculated results from static thrust characteristic analysis with measured statistics obtained from a prototype LOA. This analysis of static thrust characteristics used the FEM (Finite Element Method) for the analytical to obtain the static thrust characteristics from the distribution of magnetic flux density at the air gap center by application of Maxwells stress law.After making and testing a prototype LOA, we found that the LOAs static thrust characteristics achieved the values intended in the design.We also determined, at the laboratory level, that the LOAs frequency characteristics show that the LOA can obtain the required frequencies.
