新结构无刷电励磁同步电机设计与分析
|
摘要
提出了一种新结构的无刷电励磁同步电机,该电机取消了传统的同步电机转子侧的电刷和滑环,且其不需要单独的励磁机与同步电机相连,使得电机结构得到简化,提高了同步电机系统的功率密度,并同时具有可控性好,运行可靠,易于维护等优点。运用Ansoft软件设计了一台11 kW的无刷电励磁同步电机,仿真分析了该同步电机的磁力线、磁密分布、损耗等。并研制一台样机进行实验研究,进一步验证了所研究的新型无刷电励磁同步电机在理论分析、电磁设计上的合理性,同时也证明了整个无刷电励磁系统方案的可行性。
A novel structural brushless electrically excited synchronous motor was presented,which eliminated conventional synchronous motor brushes and slip rings on rotor side,and required a separate exciter connected with the synchronous motor. The motor structure was simplified and the power density of synchronous motor was improved. It has advantages of good controllability,reliable operation,easy maintenance,etc. Ansoft software was used to design a 11 kW brushless electrically excited synchronous motor, and the synchronous motor's magnetic field lines,flux density distribution,loss,etc were simulated. A prototype was designed and manufactured for experimental research. The novel structural brushless electrically excited synchronous motor in the theoretical analysis and the electromagnetic design which is reasonable were validated,and the whole brushless excitation system's feasibility was proved.
