A variable frequency drive is a type of motor controller that initiates electric motor by changing the frequency and voltage supplied to the electric motor. There are many other names of variable frequency drives such as variable speed drive, adjustable frequency drive, adjustable speed drive, AC drive, microwave, and inverter.
It changes the capacity of the artificial lift system by varying the motor speed. Eminent variable frequency drive pump manufacturers make high-quality VFD for different industries. And the recent improvements to the VFD feature set mean they offer more than just their well-known energy saving capability, particularly when paired with a motor or compressor system.
Here are some reasons why you might want to deliberate using a VFD on your compressor application:
1. Energy Efficiency
The most evident advantage of a VFD is the notable energy efficiency. Generally, the compressor application setup uses a direct electrical supply to power a motor that then runs the compressor. And the compressor uses the energy output it needs from the motor. In case, if the motor is controlled by a VFD then the frequency of the electricity powering the motor can be changed. Though, the speed of the motor can be regulated according to the demands of the application. If the less power is required then the drives adjust the electrical frequency, slowing the motor. And the industry can achieve energy efficiencies and cut costs by using VFD to control their compressors.
2. Advanced Functionality
Now, VFDs are becoming more advanced, offering exceptional feedback and monitoring capabilities. When a given variable changes, the drive can be set up to automatically adopt the frequency by altering the speed of the motor. VFDs can be set up to monitor the motor temperature. It can also automatically lower the motor speed, sends error signals or stops the motor altogether. And it can also monitor compressor oil pressure, eliminating the need to do so manually. This advanced functionality of VFD can improve the performance of your application and also allow you to add additional monitoring of variables as required.
3. Lower Starting Current
A VFD can reduce the starting current without affecting the starting torque. And by enabling the lower starting current, the energy grid is placed under less stress when motors are powered up, reducing the impact on other logical grid energy consumers. And the resulting lower energy frequency variations also mean that failure of electrical equipment can be reduced.
As drives functionality is becoming more advanced, the variable frequency drive pump manufacturer takes steps to simplify the usability and the commissioning process, for making the benefits of VFDs more accessible to a wide range of industrial manufacturers.
