Variable Frequency Drive and Motor Control

Modern technology has helped to create electrical systems that are more efficient and cost-effective than ever before. A Variable Frequency Drive (VFD), for example, is a controller component that can vary the frequency and voltage delivered to your electric motor. A VFD can go by many names, including:

  • Adjustable frequency drive
  • Variable speed drive
  • AC drive
  • Inverter
  • Microdrive

How Does VFD Work?

Basically, a VFD helps to regulate the RPMs with your motor speed. A higher frequency will increase the rotations per minute. 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.

The Benefits of Variable Frequency Drive

To some, a VFD motor control may not sound like something worth investing in. Colorado Lighting is here to provide variable speed motor options to help maximize efficiency in all forms for your electric motor. In most applications, your business can benefit from VFD for several key reasons.

  • 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 results. 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. Less operational errors will lead to better efficiency.
  • 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.

While Variable Frequency Drive, you can expect a wide range of benefits that come from delivering the most efficient option for matching the output for your electric motor. It’s important to remember that VFDs can be very complex devices that can change in cost or complexity based on your industry-specific needs.
