Multi-material Topology Optimization of Permanent Magnet Motor with Arbitrary Adjacency Relationship of Materials

2.5-D Multi-Phase Topology Optimization of Permanent Magnet Motor Using Gaussian Basis Function

“…For a 2-D multi-phase topology optimization using Gaussian basis functions [6,7], we introduce the shape functions 𝑦 1 (𝒙, 𝒘 1 ) and 𝑦 2 (𝒙, 𝒘 2 ) defined by…”

“…To validate the performance of the proposed 2.5-D topology optimization, we further solved (5) using 2-D topology optimization [6,7]. The solution for the latter case was obtained by simply setting 𝐿 = 1 in the proposed 2.5-D optimization.…”

“…In contrast to the above-mentioned parameter-based optimization, the topology optimization in which the material shape is freely deformed allowing the generation and annihilation of holes can lead, in principle, to novel machine structures [3]− [7]. Topology optimization that represents material distribution using Gaussian basis functions is effective for the design of rotating machines [5]− [7].…”

“…In contrast to the above-mentioned parameter-based optimization, the topology optimization in which the material shape is freely deformed allowing the generation and annihilation of holes can lead, in principle, to novel machine structures [3]− [7]. Topology optimization that represents material distribution using Gaussian basis functions is effective for the design of rotating machines [5]− [7]. This method can deal with multi-phase topology optimization, which simultaneously determines the distributions of flux barriers, magnetic materials, and permanent magnets with different magnetizations.…”

An efficient combination of topology optimization and parameter optimization for electromagnetic devices

“…TO methods were originally developed by the structural and mechanical community in the 60s [1]- [2]. As the capabilities of modern computers increase, the TO has found application in the applied electromagnetics community for the conceptual design of electric devices [3]- [7].…”
