- 电机是使机械能与电能相互转换的机械,直流电机把直流电能变为机械能。作为机电执行元部件,直流电机内部有一个闭合的主磁路。主磁通在主磁路中流动,同时与两个电路交联,其中一个电路是用以产生磁通的,称为激磁电路,另外一个是用来传递功率,称为功率回路或者电枢回路。-Motor is to convert between mechanical energy and power of machinery, the DC to DC motor into mechanical energy. Executive

- 空间电压矢量控制PWM(SVPWM)也叫磁通正弦PWM法.它以三相波形整体生成效果为前提,以逼近电机气隙的理想圆形旋转磁场轨迹为目的,用逆变器不同的开关模式所产生的实际磁通去逼近基准圆磁通,由它们的比较结果决定逆变器的开关,形成PWM波形.此法从电动机的角度出发,把逆变器和电机看作一个整体,以内切多边形逼近圆的方式进行控制,使电机获得幅值恒定的圆形磁场(正弦磁通).-Space voltage vector control PWM (SVPWM), also known as magnetic

- 交流电动机的矢量控制(Transvector Contrl)理论,从理论上解决了交流电动机转矩的高性能控制问题。其基本思想是在普通的三相交流电动机上设法模拟直流电动机转矩控制的规律,在磁场定向坐标上,将电流矢量分解成产生磁通的励磁电流分量 和产生转矩的转矩电流分量 ,并使两分量互相垂直,彼此独立,然后分别进行调节。这样,交流电动机的转矩控制,从原理和特性上就与直流电动机相似了。因此,矢量控制的关键仍是对电流矢量的幅值和空间位置的控制。-AC motor vector control (Trans
