Study your application careful before select VFD
http://www.vfds.in/study-your-application-careful-before-select-vfd-265332.html
Study your application careful before select VFD. Study your application careful before select VFD. Before you select any motor for your particular application purpose you should careful study which one is better. In one of my project that we retrofit an old CNC machine, I advise my team to remove all motors that equipped in the original machine as all of them are old and less efficiency. One of the pitfall that I overlook is EMI problem of VFD that we use for spindle. Since VFD. VFD manufacturers have r...

Frequency converter Q&A
http://www.frequencyinverter.org/frequency-converter-qa-401784.html
Frequency converter, also called variable frequency drive, typically controls a motor's velocity or torque output. Most frequency inverters today use pulse width modulation or PWM. By varying the pulse width, converters create an output waveform with an average that is a sinusoidal voltage and current waveform for which frequency can be varied. It is this variable output that is used to control motor speed, torque, or position. In the intermediate dc circuit, the dc voltage goes through a low-pass filter.
