【摘要】：双正弦无刷双馈电机是将正弦结构引入到无刷双馈电机转子绕组的基础上设计出来的。文章利用Ansoft/Maxwell 2D建立双正弦无刷双馈电机的有限元模型,通过电机外电路添加激励,对电机模型进行有限元仿真;依据仿真结果,并结合电机的磁力线分布、电机转速与频率的对应关系以及气隙磁密等验证了电机设计的可行性与合理性;在此基础上,通过与传统的特殊笼型转子和等匝绕组式转子结构的无刷双馈电机对比分析,表明双正弦无刷双馈电机在增强磁场调制效果和降低气隙谐波方面有较大的优越性,进而为深入研究双正弦无刷双馈电机奠定了基础。
[Abstract]:The double sinusoidal brushless doubly-fed machine is designed on the basis of introducing sinusoidal structure into the rotor windings of brushless doubly-fed motor. This paper uses Ansoft/Maxwell. 2D finite element model of double sinusoidal brushless doubly-fed machine is established. The finite element simulation of the motor model is carried out by adding the excitation to the external circuit of the motor. According to the simulation results, the feasibility and rationality of the motor design are verified by combining the distribution of the magnetic force line of the motor, the corresponding relationship between the motor speed and the frequency, and the air-gap magnetic density. On this basis, the brushless doubly-fed machine with traditional special cage rotor and equal turn winding rotor structure is compared and analyzed. It is shown that the double sinusoidal brushless doubly-fed machine has great advantages in enhancing the magnetic field modulation effect and reducing the air gap harmonics, thus laying a foundation for the further study of the double-sinusoidal brushless doubly-fed machine.
