直线感应电机由于其结构的不同，各相的常数是不同的。建立不对称常数的计算方法是很重要的，因为不对称常数会引起推力脉动。本文提出了一种计算直线电机非对称常数的新方法。并将计算出的参数与实验结果进行了比较。直线电机试验机为单面、短一次型、三相四极电机。一次绕组线有双层绕组、集中绕组和全节距绕组。本文首先在合适的d-q轴上给出了直线电机的不对称等效电路和电压方程。其次，通过d轴等效空载试验、q轴等效空载试验、三相等效空载试验、d轴锁定试验和q轴锁定试验的计算得到不对称常数。在这里，等效空载试验是从直线电机上取下非磁导体板的锁定试验。结果表明，利用计算常数对推力脉动和一次电流的模拟结果与实验结果吻合较好。
The constants of each phase of linear induction motor(LIM) are different, because of it's structure. It is important that the method of calculating asymmetrical constants is established, because the asymmetrical constants cause the thrust pulsation. In this paper, a new method of calculating asymmetrical constants of LIM is proposed. Moreover, the results of simulation performed by the calculated constants are compared with the experimental results.The test machine of LIM is single-sided, short-primary-type, three-phase and 4-poles. The primary winding wires are double layer winding, concentrated winding and full pitch winding. In this paper, first, the asymmetrical equivalent circuits and voltage equations of LIM are showed on suitable d-q axis. Next, the asymmetrical constants are obtained by the calculations based on d axis equivalent no-load test, q axis equivalent no-load test, three-phase equivalent no-load test, d axis lock test and q axis lock test. Here, the equivalent no-load test is the lock test removed the non-magnetic conductor plate from LIM. Finally, it is showed that the simulations results of thrust containing pulsation and primary currents performed by the calculated constants are satisfactorily agreed with experimental results.
