Electric motor power efficiency has taken center stage. Individuals, corporations, and governments are increasingly interested in saving power, now that technology can make it possible and economy ...

The motor calculations presented here apply to changing conditions of a blower motor when pulley adjustments are made. However, these calculations are useful wherever electric motors are used. These ...

Why is Power Factor important? The phase relationship between the ac-power-line voltage and current is related by a term called power factor. For a purely resistive load on the power line, voltage and ...

Recent studies indicate the level of knowledge and implementation of motor system energy-efficiency measures is low. A plethora of information on motor system design, best practices, purchasing, and ...

Two expectations informed end-users have of electric motor service centers are reliable best practice repairs and root cause failure analysis (RCFA) to prevent recurring failures. Service centers ...

If there's one major thing that's holding back an electric revolution in the aviation world, it's energy storage. But there are a ton of very clever people banging away at the problem of how to ...

Widespread usage of technology and rapid digitization are resulting in fundamental restructuring of the automotive market. With rising awareness about greenhouse gases and their effect on the global ...

Active power factor correction can achieve very high power factors—0.98 and above—with reasonably sized components, though the energy efficiency may be slightly lower than with passive techniques (94 ...
