Variable Frequency Inverter
Variable Frequency Inverter
Variable Frequency Inverter controls the speed and torque of an AC motor by converting fixed frequency and voltage input to a variable frequency and voltage output. System performance is greatly improved by controlling speed to precisely match the realtime load.
Besides system optimisation and motor efficiency, VFD motor control is one of the 3 main areas to achieve energy savings. Savings will depend on the nature and variability of the load and total operating hours. Where process output requirements vary by 30% or more, matching the load with a VFD can reduce energy use significantly.
Motor systems equipped with a VFD can bring benefits including…
- Reduce maximum power demand
- Reduce stress on system components
- Accurate control of process signals… pressure, flow, temperature etc
- Improved safety and amenity, through reduced heat and noise levels
- Integration of VFD control with building management systems (BMS)
Seamless Process Automation Limited has a wealth of knowledge across all the leading variable frequency inverter brands. We take pride in being experts in the integration of variable frequency inverters within a wide range of industrial and commercial applications.
Popular brands of VFDs we supply across Kenya are
Variable frequency inverters (VFDs) work by varying the AC electrical input frequency to control drive speed. They are preferred due to their accurate speed variability from zero rpm to over 100% rpm of the rated speed. VFDs also enable motor control in either direction.
VFDs may be of little benefit where precise motor speed control does not assist the production process, or where hours of reduced demand are few. VFDs are also not recommended for applications in which slowing down the machine causes operating problems, such as poor cooling.
