本文提出了一种用小容量直流电源装置进行直线感应电动机静态特性试验的方法，暂称直流衰减试验法。该方法可以通过一次测试确定从工业频率附近到小于0.1Hz的直线感应电机的精确阻抗。在每个滑移的特性预测使用两个反应理论。起动推力和起动电流的实测值与计算值的对比表明了该方法的有效性。此外，我们还评估了条件（即，间隙、结构和材料）影响线性感应电动机的性能，即，通过所提出的测试方法计算的推力、电流和阻抗特性。这种方法适合于计算直线感应电动机的性能，因为它不需要空载测试，这是很难执行的直线感应电动机用于控制用途，或锁定测试，其中的动子必须制动。
This paper presents a method to calculate the characteristics of linear induction motors by a simple standstill testing method using a small-capacity DC power supply unit, tentatively called the DC decay testing method. This method can determine by a single test the accurate impedance of linear induction motors from the vicinity of commercial frequencies to less than 0.1Hz. The characteristics at each slip are predicted using the two-reaction theory. Comparisons of measured and calculated results for starting thrusts and starting currents demonstrate the validity of the proposed testing method. In addition, we evaluate how conditions (i.e., gap, structure and material) of the secondary-side conductor affect the linear induction motor's performance, i.e., thrust, current and impedance characteristics as calculated by the proposed testing method. This method is suited to calculating the performance of linear induction motors because it does not require no-load tests, which is difficult to carry out for linear induction motor for control use, or locked tests, where the mover must be braked.
