8、按比例地改V和f时，电机的转矩如何变化?

频率下降时完全成比例地降低电压，电机将造成在低速下产生地转矩有减小的倾向。因此，在低频时给定V/f,要使输出电压提高一些,以便获得一定地起动转矩,这种补偿称增强起动。可以采用各种方法实现,有自动进行的方法、选择V/f模式或调整电位器等方法。

9、在说明书上写著变速范围50~5Hz，即10:1，那么在6Hz以下就没有输出功率吗?

在6Hz以下仍可输出功率，但根据电机温升和起动转矩的大小等条件，最低使用频率取6Hz左右，此时电动机可输出额定转矩而不会引起严重的发热问题。变频器实际输出频率(起动频率)根据机种为0.5~3Hz.

10、对于一般电机的组合是在50Hz以上也要求转矩一定，是否可以?

通常情况下时不可以的。在50Hz以上，电压不变，大体为恒功率特性，在高速下要求相同转矩时，必须注意电机与变频器容量的选择。
