Three-Phase Frequency Converter 380V 7.5KW-450KW

Targeting high-precision machine tools such as CNC lathes, milling machines, and machining centers, it addresses the process pain points of traditional speed regulation methods, namely "large speed fluctuations and low positioning accuracy". Adopting advanced vector control technology, the speed adjustment range reaches 1:10,000, and the positioning accuracy error is controlled within 0.001mm. It is suitable for the complex working conditions of "high-speed cutting + low-speed feed" of machine tool spindles. For example, when processing stainless steel parts, it can ensure surface finish through 5Hz low-speed feed and improve efficiency through 150Hz high-speed cutting. The product qualification rate has increased by 25% to 30%. Supports torque control mode to maintain a constant torque during heavy cutting (such as milling thick steel plates), preventing spindle jamming. The soft start function can reduce the mechanical shock during the spindle startup and extend the bearing life by m…
