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 typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

The Powermatic 2014B Lathe from Powermatic Tools, JPW Ind. has a heavy-duty, cast-iron construction across the bed, legs, headstock and tailstock, and an adjustable leg stand design that further ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

Increasingly common, variable frequency drives (VFDs) are used to control motor speed — elevating the frequency of power pulses/sec fed to motors for faster turning, and decreasing that frequency to ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

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 ...

Motors controlled by variable frequency drives (VFDs) are vulnerable to electrical bearing damage. A savvy specifier will choose new motors that are already equipped with shaft grounding rings, but ...

Predictive maintenance and on-site monitoring of pumps, pipes and motors can also help increase energy efficiency.However, one often overlooked strategy that has proven both accessible and effective ...

When selecting the most efficient and cost-effective variable frequency drive (VFD), it’s essential to understand the specific considerations involved in your commercial venture. No two industrial ...

OEMs and hobbyists benefit from technology’s trickle-down effect. Figure 1. Many industrial applications and small machines with a motor and limited I/O requirements can benefit from using AC VFDs with ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...
