PurposeThe purpose of this paper is to propose a mechanism avoiding the topology optimization methods, and particularly those using gradient‐based algorithms, to be trapped in local minimizers when applied to the design of electromagnetic devices m

Topology optimization methods suffer from a lack of convexity for the design of electromagnetic devices. Local minimizers indeed prevent deterministic methods from attaining the optimal solution. The optimization result may then vary according to the

When applied to the topology optimization of electromagnetic devices, gradient-based algorithms suffer from a lack of convexity. They usually converge to local minimizers and the obtained designs depend on the initial material distributions. This pap

In aerospace applications, high reliability drives are required. For electrical drives based on three phase PMSM, a way to improve the reliability is to allow a degraded mode operation on two phases only, thanks to specifically developed power and co

In order to perform parameter or shape optimizations, an initial topology is required which affects the final solution. This constraint is released in topology optimization methods. They are based on a splitting of the design space into cells, in whi

This paper focuses on the maximization of the torque-to-weight ratio of permanent magnet synchronous motors (PMSM) using a topology optimization method. It aims at finding the optimal design that either maximizes the torque for a given weight or mini

In the topology optimization of electromagnetic devices, the convexity-oriented mapping method is efficient at avoiding local minimizers. The results are not affected by the initial material distribution and are in practice better than those obtained

This paper deals with the modelling and the control of a five-phase machine using a tooth-concentrated winding technology. It is shown that the control of the torque can be easily performed in a generalized dq reference frame, and that with this cont
