    • 摘要: 直线电机边端效应是由定子铁心、次级开断所致的固有效应,该效应会引起电机电磁推力的不同频率的脉动。本文首先基于电磁推力公式对边端效应所致的推力脉动频率进行了理论分析。然后利用一维磁路法对动态纵向边端效应引起的次级感应涡流沿轴向的分布规律进行了理论分析和解析计算,根据次级感应涡流进而计算得到了动态纵向边端效应引起的转差频率两倍频推力脉动幅值的解析表达式,并得到了推力脉动幅值和不考虑边端效应时的电磁推力值的比例关系,最后通过峰值功率20 MW,最大出力900 kN的大功率直线感应电动机实验系统对分析结论进行了试验验证。理论分析和试验结果表明:计及边端效应时直线电机电磁推力存在供电频率两倍频和转差频率两倍频的脉动,其中转差频率两倍频的脉动由动态纵向边端效应导致,主要和次级极数以及转差频率有关。%End effect, which results in the thrust ripple of different frequencies, is the inherent character-istic of linear induction motor ( LIM) . A study of thrust ripple on LIM was conducted. First, thrust ripple frequencies was obtained according to electromagnetic thrust calculation formula. Secondly, theory analy-sis and analytic calculation for distribution of inductive eddy current on secondary with a view to dynamic longitudinal end effect was presented based on magnetic circuit. Then, according to inductive eddy cur-rent on secondary, the expression of thrust ripple value at the frequency of twice of the slip frequency was obtained. Lastly, theory analysis and calculation results were validated by test data from the long primary DLIM system capable of producing 900kN of force, operating at the 20MW peak power level. The result indicates that there exists thrust ripple at twice the slip frequency and work frequency. Thrust ripple scale of twice the slip frequency, which results from dynamic longitudinal end effect, is related to slip frequen-cy and secondary poles.

    • 摘要: For investigating the performance of constant and adaptive speed regulation of cascaded linear induction motor (LIM)in maglev system,a new speed-sensorless vector controller was designed based on the Maxwell equations by analyzing the relationship between the thrust of the LIM and the current vector of the primary winding. The reasonability and the effectiveness of this controller were verified by numerical simulation using Matlab/Simulink. The results show that when facing small perturbation of the speed,the controller can automatically adjust the DC bus voltage of the rectifier through the inner current loop and the outer voltage loop to stabilize the speed within 10 ms. When receiving the reference speed value,the frequency of the AC side of the inverter is regulated to obtain a suitable value of the synchronous speed;the regulating time is less than 50 ms and within 3 cycles of power frequency,meeting the requirements of control performance in maglev system.%为了研究磁浮系统中的恒速驱动及适时速度调节性能,根据Maxwell方程及电机的矢量控制原理,以磁浮系统中的直线感应电动机为研究对象,在其推力与初级绕组中电流矢量关系的基础上,设计了无速度传感器矢量控制器,并利用Matlab/Simulink软件验证控制器的正确性。研究结果表明:当速度在小范围内受扰动时,控制器运用电流内环、电压外环控制方式自动调节整流器的直流母线电压,调节时间小于10 ms;当控制器接收到指令速度时,改变逆变器的频率,该频率改变电机同步速,达到调速的目的,调节时间小于50 ms,表明在工频小于3个周期时,满足磁浮系统的控制要求。
