Design Optimization and Performance Analysis of Rectangular Structured Moving Magnet Linear Actuator

This article examines a new linear oscillating actuator (LOA) design that uses rectangular-shaped core materials and permanent magnets (PMs). The paper's primary objective is to examine a novel LOA topology with a rectangular-shaped core and PMs as an alternative to the tubular LOA. A Static core material is housed between the mover's components, and two stator cores with two coils each are placed on either side of the mover. The dimensions of all the parameters are swept for optimization, and the optimal parameter dimension is chosen based on the optimal value of the electromagnetic (EM) force. An analysis is done for output parameters like EM force and stroke. EM force per PM mass of the investigated design of LOA is 67 percent higher than of conventional rectangular-shaped LOA. Additionally, the proposed design's EM force density is 23.8 percent higher than that of the conventional design of LOA. Furthermore, the stroke of the proposed LOA is also feasible and more than most of the designs of the LOA. Additionally, the proposed design of the LOA is simple structure, low-cost, and feasible for fabrication.
