Overview of the Optimal Design of the Electrically Excited Doubly Salient Variable Reluctance Machine

The Electrically Excited Doubly Salient Variable Reluctance Machine (EEDSVRM) is a new type of brushless machine designed according to the principle air gap reluctance change. There neither permanent magnet steel nor excitation winding on rotor. rotor made silicon sheets, thus structure variable very simple. are many optimization methods for this optimal design, such as novel topology optimization, finite element simulation-based mathematical analysis-based intelligent algorithm-based and multiple fusion-based optimization. Firstly, article introduces basic working EEDSVRM analyzes both its common regularity individual difference. Then, different design reviewed, advantages disadvantages summarized, research interests machines in future prospected.
