在实际的电机控制中，电机内部存在电流反电动势这样的因素，当不考虑这些因素时，转子可能出现不稳定的振动或意想不到的旋转方向。这时，采用零矢量的控制方法可以使电机的转子运动平滑，减小转子损耗和机械振动，同时也可以降低电机的噪音。

在SVPWM控制方法中，零矢量的作用具体体现在以下几个方面：

1. 平滑转子运动：零矢量可以使电机的转子运动更加平滑和稳定，减少振动和机械损耗。

2. 减小噪音：零矢量可以降低电机的噪音，使电机运行更加静音。

3. 降低电源电流峰值：零矢量的引入可以降低电机启动时的出现的电源电流峰值。

综上所述，零矢量是SVPWM控制方法中的一种特殊调制方式，通过协调各相电压信号的调制比例来实现平滑运行，减小噪音，降低电机的运行损耗。
