摘　　要：给出了为研究直线电机作用下的超导磁悬浮小车的驱动力而设计的模型,模型主要是工作电路部分和实验导轨机座。在实验部分,通过对小车爬坡能力的测量,来研究不同电容情况下,直线电机驱动力大小的变化。从理论上分析在理想直线电机作用下的电容大小和电机驱动力的关系。实验表明,当电容大小取20μF时,直线电机的驱动力最大。The maglev car model that is designed to investigate the drive force from the linear motor was showed, the model has two main parts： the electrical circuit and magnetic track for experiment. The main work is a electrical circuit, shah change the single phase alternating current to the three phases alternating current by a capacitance. The result of the experiment was given. Finally, the relationship between the capacitance and drive force was analyzed theoretically, and compare with the experiment result, investigate that brings the differences of the two. The driving force is max when the capacitance value is about 20 μF.
