Traction Drives Traction drives depend upon friction between a speed adjusting mechanism and specially shaped input and output plates to achieve adjustable speed with relatively high efficiency. In ...

Adjustable speed drives change the speed of a driven shaft to a speed selected by the operator. Additionally, these drives are used to maintain the speed of a machine to very close tolerances: ±0.1% ...

Slowing down the fan saves the unneeded air flow and saves the horsepower of the fan, which saves money. The device that controls the fan speed is called a variable speed drive. Variable frequency ...

West Fraser, a diversified wood products company, has made significant gains towards stringent carbon-reduction and energy ...

Rear-end crashes have been plaguing the Schuylkill Expressway for years. If you drive the Schuylkill, you know, the twists and turns combined with traffic which often stops on a dime can be dangerous.

WEG’s integrated drive package, including flameproof electric motors, variable speed drives (VSDs) and transformers, will help maximise the efficiency, reliability and safety of the horizontal ...

How variable frequency drives reduce energy consumption by controlling motor speed and torque to support industrial energy efficiency and sustainability goals. AC induction motors are widely used in ...
