Electromagnetic-thermal Coupled Analyses and Joint Optimisation of Electrically-excited Flux-switching Linear Machines
文献摘要：
Electrically-excited flux-switching machines are advantageous in simple and reliable structure, good speed control performance, low cost, etc., so they have arouse wide concerns from new energy field. However, they have much lower torque density/thrust density compared with the same type PM machines. To overcome this challenge, electromagnetic-thermal coupled analysis is carried out with respect to water-cooled electrically-excited flux-switching linear machines (EEFSLM). The simulation results indicate that the conventional fixed copper loss method (FCLM) is no longer suitable for high thrust density design, since it is unable to consider the strong coupling between the electromagnetic and thermal performance. Hence, a multi-step electromagnetic-thermal joint optimisation method is proposed, which first ensures the consistency between the electromagnetic and thermal modelling and then considers the effect of different field/armature coil sizes. By using the proposed joint optimisation method, it is found that the combination of relatively large size of field coil and relatively low field copper loss is favourable for achieving high thrust force for the current EEFSLM design. Moreover, the thrust force is raised by 13-15％ compared with using the FCLM. The electromagnetic and thermal performance of the EEFSLM is validated by the prototype test.
