Shape and topology optimization of rotor in synchronous reluctance motor using continuum sensitivity and adaptive level set method

In this paper, the rotor shape of synchronous reluctance motor (SynRM) is designed using the sensitivity analysis along with the level set method. To reduce numerical errors of sensitivity value on the interface, the adaptive level set method is adopted. The rotor shape of the SynRM is designed to maximize average torque or to minimize cogging torque by distributing the ferromagnetic material over the design domain of the rotor.
