dc.titleOptimal design of a novel linear motor based on general topology patternsen_US
dcterms.abstractA general topology pattern of linear motor is proposed in this thesis. Through the general pattern, five common types of linear motor can be obtained, namely, surface-mounted permanent magnet linear motor (SMPM), surface-mounted permanent magnet vernier linear motor (SMVPM), flux-concentrated permanent magnet linear motor (FCPM), flux-concentrated permanent magnet vernier linear motor (FCVPM) and flux switching linear motor (FSPM). Based on the finite-element method (FEM), these types of motor are simulated and optimized to obtain the best-performed model with the proposed pattern. The optimization method is genetic algorithm (GA). The performance of the motor can be evaluated by average thrust force, output force ripple, efficiency, power factor, harmonic components and etc. The importance of these parameters vary in different situations. In this thesis, the average thrust force, output force ripple and efficiency are taken into consideration.en_US
