Energy conservation using high-efficiency electric motors

Data on electrical energy conservation using high efficiency motors for the confidence bounds using statistical techniques

In this article, we describe details of the data used in the research paper "Confidence bounds for energy conservation in electric motors: An economical solution using statistical techniques" [1]. The data presented in this paper is intended to show benefits of high efficiency electric motors over the standard efficiency motors of similar rating in the industrial sector of Pakistan. We explain ...

High Efficiency Single Phase Motors

Since the energy efficiency ratio (EER) of the air conditioning system is dependent on the efficiency of the motor in addition to the performance of the refrigerant system. the motor efficiency can be viewed as a source of EER improvement. The amount of motor efficiency improvement obtainable is in turn dependent on the motor material characteristics and the motor size or volume which is usuall...

Energy Efficiency of Electric Vehicles

Fan-shape optimisation using CFD and genetic algorithms for increasing the efficiency of electric motors

The electric motor efficiency represents the effectiveness with which the motor converts electrical energy into mechanical energy. As the energy losses are converted into heat, which is dissipated by the motor frame aided by internal and external fans, a better cooling system adds up to better efficiency. In recent years, improvements in motor efficiency have been achieved but at higher costs. ...

Energy Saving in Evaporative Coolers using Permanent Magnet Brushless Motors

Due to low cost, evaporative coolers are used in most of the central regions and in the warm and dry climate of Iran and are considered as one of the major consumers of electrical power. Most evaporative coolers use single-phase induction motors by connecting directly to the power grid. But their eefficiency is very low, and their replacement with high efficiency electric motors is considered b...
