Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

The U.S. Department of Energy has indicated that 65 percent of electrical energy used in commercial and industrial systems comes from electrical motors powering centrifugal pumps and fans. Also, the ...

Measurements and analysis on three-phase power systems are inherently more complex than on single-phase systems. Learn more about 3-Phase IMDA. Although oscilloscopes can capture voltage and current ...

So you just spent three hours removing and replacing a motor that drives the feed to a robotic welder. You connected the leads exactly the way they were before you disconnected them. You properly ...

The road to energy efficient HVAC may lead to variablespeed compressor technology and new electronics to drive it. Most engineers know that heating, ventilation, and air conditioning (HVAC) systems ...

The experts at eMotors Direct outline how VFD’s can damage bearings and discuss preventative measures to prevent VFD induced bearing damage Electric motors fitted with VFDs (Variable Frequency Drives) ...
