变频器驱动时的起动转矩和大转矩要小于直接用工频电源驱动。 

电机在工频电源供电时起动和加速冲击很大，而当使用变频器供电时，这些冲击就要弱一些。工频直接起动会产生一个大的起动起动电流。而当使用变频器时，变频器的输出电压和频率是逐渐加到电机上的，所以电机起动电流和冲击要小些。 

通常，电机产生的转矩要随频率的减小（速度降低）而减小。减小的实际数据在有的变频器手册中会给出说明。 

通过使用磁通矢量控制的变频器，将改善电机低速时转矩的不足，甚至在低速区电机也可输出足够的转矩。 

当变频器调速到大于50Hz频率时，电机的输出转矩将降低  

通常的电机是按50Hz电压设计制造的，其额定转矩也是在这个电压范围内给出的。因此在额定频率之下的调速称为恒转矩调速。(T=Te, P<=Pe)  

变频器输出频率大于50Hz频率时，电机产生的转矩要以和频率成反比的线性关系下降。 

当电机以大于50Hz频率速度运行时，电机负载的大小要给予考虑，以防止电机输出转矩的不足。 

举例：电机在100Hz时产生的转矩大约要降低到50Hz时产生转矩的1/2。 

因此在额定频率之上的调速称为恒功率调速。(P=Ue*Ie)
