对中低速磁浮列车的直线牵引电机特性设定的初步意见

An Initial Suggestion of Establishing Character for Linear Motor in M&L Speed Maglev Train

与交流旋转异步牵引电机相类似,直线交流牵引电机在运行中,其输出牵引力也控制成恒力和恒功2个状态,可以充分发挥电机的固有特性。为此,选择恒力和恒功转折频率就非常重要了。通过对一台使用过的直线电机特性的分析和计算,得出了特性设定的意见。

Similar to AC asynchronous motors, the traction of running linear motors is controlled into two states, constant force and constant power, which can make full use of motor＇s inherent characteristics. So it is very important to select the turnover frequency between constant force and constant power. An initial suggestion of setting characteristics is presented by analyzing and calculating one used linear motor＇s characteristics.
