在做无传感器控制时,修改电机参数,Base_Voltage 是说电机的额定电压峰值吗? 后面的Vdc/ 根号3是什么意思?
不太懂 这里的Base_Voltage 怎么取值
// Define the base quantites
#define BASE_VOLTAGE 236.14 // Base peak phase voltage (volt), Vdc/sqrt(3)
#define BASE_CURRENT 10 // Base peak phase current (amp), Max. measurable peak curr.
#define BASE_TORQUE // Base torque (N.m)
#define BASE_FLUX // Base flux linkage (volt.sec/rad)
#define BASE_FREQ 200 // Base electrical frequency (Hz)
关于这几个量如何设置,请查看如下:
// Define the base quantites #define BASE_VOLTAGE 236.140 // Base peak phase voltage (volt) //对应最大相电压,由电压采样电路决定,如VDCmax/3^0.5 #define BASE_CURRENT 10 // 实际为最大电流,由板上电流采样电路硬件决定,对于TI高压电机套件,10A时对应到ADC输入管脚为3.3V或者0V, #define BASE_TORQUE // Base torque (N.m) #define BASE_FLUX // Base flux linkage (volt.sec/rad) #define BASE_FREQ 100 // Base electrical frequency (Hz),电机内电气频率,可以根据实际电机调整,如最大电机速度6000RPM, //可以这样设:BASE_FREQ=(6000/60)*Poles/2.
