WZ series eddy current brake for hoisting and metallurgy

 

 

 

 

WZ系列起重及冶金用涡流制动器符合JB7561-94《WZ系列起重及冶金用涡流制动器技术条件》。涡流制动器和YZR系列绕线转子电动机配合使用，通过控制器能把驱动和调速两种功能协调起来（开环控制时可达到1：10，闭环控制时可达到1：20的调速宽度），具有稳定的低速调速特性和无失控区、运行可靠等优点。

 

 

 

WZ series eddy current brake for lifting and metallurgy meets jb7561-94 technical conditions for WZ series eddy current brake for lifting and metallurgy. The eddy current brake and YZR series wound rotor motor are used together, and the two functions of drive and speed regulation can be coordinated through the controller (the speed regulation width can reach 1:10 in open-loop control and 1:20 in closed-loop control), which has the advantages of stable low-speed speed speed regulation characteristics, no runaway area, reliable operation, etc.
