AC induction motors, the workhorses of the industry, rotate at a fixed speed. The fixed speed of AC induction motor is determined by the frequency of the supply voltage. Adding a variable frequency…Continue
It's said that 40% of all power in Europe and North America is consumed in the buildings. The biggest share of the energy is consumed in heating, ventilation and air conditioning (HVAC)…Continue
applications of AC variable speed drive (frequency inverter)
AC variable speed drives (frequency inverters) are widely applied in the industry today. There are three major areas, where drives and motors are applied.
1. Constant torque applications
This is where the same amount of torque is required at low speed as…Continue
pumps and frequency inverter (variable speed drive)
All of us know that frequency inverters are widely used in many applications for energy saving. They are tools that is used to change the frequency of electricity.
Below is application of frequency converter used for pumps.
Usually pumps are sized to cope with the maximum predicted flow, leading to the motors running at part load. The result is low motor efficiency and a low power factor which…Continue
