Abstract
This paper concerns the optimization of eight different quasi-Halbach magnet array structures that are used in a dual-layer moving-magnet planar motor. These magnet arrays vary in number of magnets per pole and contain both cuboidal and trapezoidal prism magnet shapes. The parameters of the magnet structures are optimized to maximize the acceleration of the planar motor. The resulting accelerations and force ripples of the planar motor are compared for the optimal magnet structures. The results show that the studied magnet arrays improve the acceleration of the planar motor compared to the benchmark magnet array with three cuboidal magnets per pole. A maximum increase in acceleration of 10.1 % is achieved, while the force ripple is reduced by 10.2 % in any direction of movement.
