Benefits of Using a Variable Frequency Drive
Variable Frequency Drives (VFD), are controller component that can vary the frequency and voltage delivered to your electric motors. A VFD can go by many names, including: Adjustable Frequency Drives, Variable Speed Drives, AC Drives, Motor Controls, Inverters and Microdrives.
A VFD helps to regulate the RPMs with your motor speed. A higher frequency will increase the RPMs. Conversely, if less RPMs are required, a variable speed drive can help to slow the motor to meet the current load demand. The converter is the first part of the system that normally consists of six diodes that bring the current in a one-way entrance. Once the current is similar enough to one diode, it will allow access. Each diode is a different phase, with a positive and negative side for each. Thus, you have six pulse options to control your motor speed.
Normally, the conversion leads to an AC ripple, where DC power is over the limits on voltage being used in the power system. A capacitor is utilized here to absorb this ripple and deliver steady DC power.
Benefits of Variable Frequency Drive
With Variable Frequency Drives, you can expect a wide range of benefits that come from delivering the most efficient option for matching the output for your electric motors. It’s important to remember that VFDs can be very complex devices that can change in cost or complexity based on your specific needs.
Lower Energy Costs – Saving energy when full speed is not needed is one of the biggest benefits of using a VFD. Load demands will fluctuate, and being able to match the speed to precisely meet the load requirement can provide major savings. Companies that upgrade to motor control systems may save upwards of 70 percent on their energy costs.
Less Wasted Use – When your motor starts and stops suddenly, wear and tear will inevitably be placed on the belts and pulley. VFDs allow for tighter control over operations, reducing the overall strain placed on your system.
Equipment Longevity – As we have said, voltage demands can fluctuate, creating the chance that some sort of error or misfire may occur. Problems such as too little or too much voltage, overheating, or any other issue resulting from an unbalanced system can be minimized by varying your motor speed for more precise results. Smoother starts and stops work to reduce the strain placed on your motor, resulting in more longevity and less downtime.
