Full-digital VFD for electric-excitation synchronous motor 

KTDK-TS-III type full digital VFD for electric excitation synchronous motor Product Overview KTDK-TS-III type full digital VFD for electric excitation synchronous motor is a special VFD for the hoist driven directly by the low-speed electric excitation synchronous motor with single or double-winding. This VFD can be directly drive the motor which voltage level motor below 10kV,  the max power could be up to 10MW, with a wider speed adjustment range and excellent low speed large torque characteristics. operational principle The KTDK-TS-III type VFD is mainly composed of power adjustment unit, excitation adjustment unit, human-machine interface and peripheral port. The VFD adopts high-performance DSP+FPGA as the main control chip. The system integrates advanced vector control, optical fiber communication, multi-level output, single / dual winding transformation control technology, and can efficiently realizes the double closed-loop adjustment of t…
