西門子變頻器制動電阻的計算方法 A、接著計算制動電阻的阻值在制動單元工作過程中，直流母線的電壓的升降取決于常數RC，R即為制動電阻的阻值， B為變頻器內部電解電容的容量。這里制動單元動作電壓值一般為710V。 C、后計算制動電阻的標稱功率由于制動電阻為短時工作制，因此根據電阻的特性和技術指標，我們知道電阻的標稱功率將小于通電時的消耗功率， 一般可用下式求得： 制動電阻標稱功率=制動電阻降額系數X制動期間平均消耗功率X制動使用率%2.6制動特點能耗制動（電阻制動）的優點是構造簡單，缺點是運行效率降低，特別是在頻繁制動時將要消耗大量的能量，且制動電阻的容量將增大。 HD SYSTEMS REDUCER GEARHEAD CP-32A-21-J602A-SP 18 21 From Korea, South New HD Harmonic Servo Head Drive Gear Reducer 5:1 CP-25A-5-J601A-SP PD-0041 HD Harmonic Servo Head Drive Gear Reducer 33:1 // CP-25A-33-J604A-SP From Korea, South Yaskawa AC Servo Motor 400W SGME-04AFJ26 &CP-35C-10-J602A Harmonic Drive Reducer From Korea, South 2011 PLATES & PATCHES A.J.
