    AID USA Can Help with Harmonic Mitigation to Avoid Penalties from the Power Company

    Variable frequency drives (VFDs) are becoming increasingly popular due to the operating efficiency they offer. However, variable frequency drives can create undesirable harmonic effects if not properly supplied. If these effects are left unchecked, they can interfere with neighboring equipment, reducing its productive life or even damaging it. They may also negatively impact your utility provider’s power quality, resulting in penalties. Passive harmonic filters can help, but they tend to reduce effectiveness at loads less than 100%, those offsetting one of the advantages of using a VFD. Adaptive passive technology,...

    Variable power is bringing manufacturers maximum efficiency

    Tyler Kern from Industrial IoT by MarketScale interviews guest, Mike Darrol, Application & Design Project Manager for AID USA The power of a Variable Frequency Drive, or VFD, cannot be understated in all industries that thrive off of efficient manufacturing. To recap, a VFD adjusts the frequency or voltage of power by variating the frequency of what’s driving the power, i.e., the motor. This is helpful for a couple of reasons: it allows companies to run three-phase power from a single phase power supply, and it allows equipment to run at a voltage...

    Reducing Motor Insulation Stress When Using Variable Frequency Drives

    A variable frequency drive (VFD), sometimes known as a variable speed drive, is used to control AC induction motor speed and torque by varying the motor input frequency and voltage.  VFDs improve control, increase efficiency, and extend the motor’s operating life by reducing mechanical and thermal stresses. However, VFDs may also lead to degradation of the coils that produce the magnetic field in the motor’s stator and their insulation. Motors Fail for Many Reasons Motors may fail for many reasons unrelated to the VFD itself. The motor’s stator windings may...
