One of the recent developments in engineering optimization is the topology optimization. This method is common in mechanical
engineering and optimization of mechanical structures, but it can be used to design novel structures of the electromagnetic
devices and electrical machines. In general, topology optimization results need a further development or post-processing to gain
a device, which is more adapted to the manufacturing process. Therefore, a hybrid optimization method is offered, which is
based on a meta-heuristic method like the Genetic Algorithm (GA). Because of irregular shapes of the optimized topologies, a
local method, called pixel connectivity technique, is presented to regularize the structure in a two-level optimization with a focus
on the improvement of the meta-heuristic method via GA and post-processing inspired by an image processing method.
The Finite Element Method is used to analyse a well-known E-core actuator developed by applying the proposed topology
optimization method as a case study. The optimization goal is to achieve the greatest savings of material and gain a lighter
weight of the device, while preserving the electromagnetic force at an appropriate level. It is possible to extend and apply this
proposed method to different active components of electrical machines in combination with other goals.
