The introductory course on motors and variable-speed drives, taught by Canadian Institute for Energy Training in collaboration with BC Sustainable Energy Association, will give participants a better ...

Available for the CFW-11 variable-speed drive, the Pump Genius process control software manages and monitors up to six pumps in a coordinated system. It can operate motors from 5-150 hp in the 208- ...

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 ...

In addition to industrial applications of variable-speed motor drives, the home appliance market is another major area where three-phase pulse width modulated (PWM) motor control drives are finding ...

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 ...

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 ...

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 ...

This is backed by new, independent research showing that drives make a major contribution in constant flow applications, where they boost efficiency by eliminating the need to oversize equipment or ...

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, ...

What is a variable frequency drive? Heating, ventilation, and air conditioning systems' air supply used to be constant volume into a space. Now a variable air volume control is being used to provide ...
