two speed ac control

基本解释

All the AC speed regulation approaches can be generalized in two basic schemes, the electromagnetic power control and the loss power control.
損耗功率控制增大的是轉速降，調速是低傚率的。
The serial communication control between PC and one DC speed regulators and two AC inverters is realized by using USS protocol based on the RS485/232 interface.
採用基於RS485/232接口的USS協議實現了工控機與一台直流調速器和兩台交流變頻器的串行通信控制。
SRD is the second DC converter, AC speed up after the development of a new type of speed control system by the switched reluctance motor and controller of two parts.
開關磁阻電機調速是繼直流調速、交流調速後發展起來的一種新型的調速系統，由開關磁阻電機及控制器兩部分組成。
