The manufacturer's ECM Comfort Speed motor has been upgraded to deliver reliable performance and the enhanced comfort and improved efficiency of a variable-speed product, according to the company. The ...

For many retrofit projects, the use of a VFD seems like a “no brainer.” Drives are now cheaper and more reliable than ever, and the benefits of efficient control of motors can’t be beat. Still, there ...

Other considerations — such as the environment in which the variable-speed drive and motor are to be placed — are also important. Philippe/Leeson: With ongoing cost pressures and limited design cycle ...

The DynaMotor from DynaMotors Inc., Warrensville Heights, Ohio (dynamotors.com), uses optically controlled solid-state switches embedded in the rotor windings to control current and, thus, torque, ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

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 ...

You can divide the world of electronic motor drives, which control the speed, torque, direction, and resulting horsepower of a motor, into two categories: ac and dc. An ac drive controls ac induction ...

Imagine an easy-to-install industrial technology that reduces energy consumption, eliminates mechanical vibrations and electronic harmonics, relaxes alignment tolerances and cuts maintenance needs.

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

Yokogawa's unique 6-channel WT1800 precision power analyser with harmonic analysis enables you to gain a complete and accurate knowledge of the power and harmonic performance of your system. Buy a ...
