摘要
变频调速技术是一种调速精度高、电机启动电流小、过载能力大 ,在电力拖动中应用最为可靠的一种调速技术。由于该技术采用的是变压变频方式 ,故在具体的应用中 ,可以获得节能降耗的效果。
Variable-frequency speed governing technology is high-accuracy and strong-overload, and it is the most reliable technology of electric drive.It can reduce the loss of power source owing to the transmission and VF technology and in this paper,the writer proposes improvement effect of the VF technology.
