摘要
简单介绍了双闭环调速系统的原理，详细阐述了小功率装置改装成大功率装置的原理和可行性，最后以西门子6RA70系列直流传动装置为例介绍了具体的改装方案。
This article roughly introduces the principle of the double closed loop speed regulation system, and in detail expounds the principle and feasibility of changing the low-power device to a high-power one. In the end, it presents a concrete face-lifting scheme, taking SIEMENS 6RA70 DC drive device as an example.
