Amps, Watts, Power Factor and Efficiency; Approximate Load Data from Amperage Readings; Power Factor Correction on Single-Induction Motors.

Conservation through lighting alterations using different bulbs, ballasts and light sources is well understood and easy to achieve. The use of improved efficiency three phase induction motors has not been as accepted. There are a number of reasons why conservation efforts with motors have not been as popular.

Understanding proper bearing lubrication procedures is critical to ensuring long-term, trouble-free performance. Klüber Lubrication has prepared this explanation as a general guide.

Part 1: There seems to be a lot of confusion about the voltage standards for motors and why they are structured the way they are. Part 2: The effect of low voltage on electric motors is pretty widely known and understood, but the effect of high voltage on motors is frequently misunderstood.

A good deal of confusion exists regarding the factors that determine an industrial electric bill. The following information is presented to help sort out the various items on which billing is based, and to offer suggestions on measures to help control and reduce electric utility bills.

Fans, blowers and other funny loads are addressend, along with RMS Horsepower loading.

In the process of applying industrial drive products, we occasionally are misled into believing that we are applying horsepower. The real driving force is not horsepower - it is torque. This paper is developed to impart a deeper understanding of torque, its relationship to horsepower, and the types of loads we most frequently encounter.

This issue we cover frame sizes and two-speed motors in our continuing series of articles, courtesy of Baldor Electric, dedicated to motor basics.

Beginning with this initial installment , and with the gracious permission of ABB/Baldor Electric, we are pleased to announce the beginning of a new series -- Baldor Basics: Motors. This is a collection of basicsdriven, motor-intensive articles authored by former Baldor engineer Edward Cowern, PE, a respected name by many in the electric motor industry. During his tenure at Baldor, Cowern - now enjoying his retirement - was tasked with producing a number of motor- and basics-related tutorials, primarily in response to a steady flow of customer questions regarding motors. Today's customers continue to ask questions and seek answers to address their various motor-related issues. As with Cowern's original introduction to the series, we hope you find these articles useful and would appreciate any comments or thoughts you might have for future improvements, corrections or topics.

If you’re an electrical engineer you know how an electric motor works; if you aren’t, it can be extremely confusing. Therefore, here’s the simplified explanation (or the “how an electric motor works for dummies” version) of how a four-pole, three-phase AC induction motor works in a car.
