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 ...

Motors are driving demand for electricity, accounting for about half of the electricity we consume, according to the Electric Power Research Institute (EPRI). Many of these motors are found throughout ...

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 ...

Variable-pitch drives are the simplest of all mechanical adjustable-speed mechanisms. Most of these drives use rubber belts. However, chain types are unmatched in regard to its particular strong ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

Applications requiring variable speed control, precision performance with low torque ripple, and high power in a compact, 1.73'' in diameter package are said to represent the primary market for NT ...

A1000 variable speed drive has a calculated design life twice as long as previous generations. Compatibility with interior and surface permanent magnet motors produces up to 200 percent torque with or ...

The MDrive34Plus2 contains a programmable digital oscillator for accurate speed control. The all-in-one system uses a NEMA Size-34 high-torque brushless 1.8° motor (NEMA Size-17 and 23 motors also ...

There’s a debate among commercial and industrial hydronic system designers: how best to refine and enhance pumping and system efficiency to precisely match output to load (need). Decades ago, ...
