机械配套使用的驱动控制装置主要包括变频器、直流调速、开关磁阻电机、齿轮机构、变极调速等，后面2种方案不能无级变速，一般用于简单变速场合或者特殊要求场合（如转矩提升），传统直流调速存在维护量大的缺点，目前在机械配套中的使用逐渐减少。新型无刷直流调速和开关磁阻电机调速具有较好的性能，但是处于推广阶段。不同的行业对传动的要求不太一样，使用的传动控制方式也有所差别，如起重机上仍然大量使用定子调压装置和转子串电阻装置，新型无梭织机使用了开关磁阻电机、橡胶压延机主要使用直流电机，新型络筒机主要使用永磁直流，但是总体而言，变频调速已经成为机械配套的主流驱动方式。随着变频器调速系统在机械特性和转矩控制精度方面的提高，变频器在相当长的时间内仍将是机械配套的主流调速装置。

The machine forms a complete system that the use drive control apparatus chiefly consists of frequency converter and the direct current accent velocity , button magnetic obstruction electrical machinery , gear organization and changes into exceedingly shifts velocity and so on , and 2 kinds of schemes can not the stepless gearshift in the rear of , oridinarily being used that the easy gearshift situation maybe specially requires the situation ( in case torque advances ) , the use during the machine being living is at the moment formed a complete system decreases traditional direct current accent velocity great defect of the amount being the protection one by one .
That the new pattern does not there is not brush direct current accent velocity and button magnetic obstruction electrical machinery accent velocity havees the better performance , yet is in the popularization phase .
The demand as far as the drive of distinct professions is very much not as , the use drive
