Introduction to VFDs Aka AC Drives Adj Freq Drives etc

There are four basic types of control for AC drives today. These are Volts per Hertz, Sensorless Vector Control, Flux Vector Control, and Field Oriented Control. • Volts/Hertz control is a basic control method, providing a variable frequency drive for applications like fan and pump. It provides fair speed and starting torque, at a reasonable cost. • Sensorless Vector control provides...
The drives and motors are from different manufacturers and vary widely in size. The vibrations seem to be consistent in that there is a vibration frequency that remains constant as …
