When applied to blowers and pumps, variable-frequency drives (VFDs) offer energy savings. In mechanical applications, they allow fine adjustments that wouldn't be possible by other methods. Despite ...

The SmartFan Stratus variable-frequency drive provides variable-speed control of single- and three-phase fans, motors, and pumps. The microprocessor-based device operates from a 115- or 230-V ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

Should you specify an “inverter duty,” “inverter ready,” “inverter rated,” or a “VFD compatible” motor for your fans and pumps in HVAC applications? Is there a difference in these terms? Don’t answer ...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

Learn the 3 key differences between soft starters and VFDs Understand the energy and operating efficiency differences between soft starters and VFDs Find out which types of industrial applications are ...

The bar continues to rise on the sanitation and sustainability contributions that motors and drives can make for food and ...

ORLANDO, Fla. — Inside HVAC forced-air and hydronics systems alike, motors are hard at work blowing air, circulating water, cooling compressors, and more. And, while there are still a significant ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

Here are the power and driver boards that [Miceuz] designed to control a three-phase induction motor. This is his first time building such a setup and he learned a lot along the way. He admits it’s ...

A variable frequency driven (VFD) is a type of motor that controls the levels of frequency and voltage that alter the speed of an electric motor. The drive alters torque and motor speed and can be ...
