TL;DR: In this article, an effective technique for estimating parameters, losses, shaft power and efficiency of three-phase induction motors in field conditions, is proposed, focused on the determination of the operating efficiency of motors under unbalanced voltages or deviated voltage and frequency without caring out special tests, removing the motors, or measuring the output power or torque.

TL;DR: In this paper, a method based on the equivalent circuits, with losses segregation and using Bacterial Foraging Algorithm (BFA) was presented to determine under field conditions and low invasiveness, energy efficiency of induction motors operating under the before mentioned conditions.

TL;DR: A methodology based on the calculation of energy-saving potential is proposed and shown to be effective by performing a preliminary an a priori evaluation and determining the economic opportunities and providing a complete economic evaluation of the final decision on the basis of discounted cash flow methods.

TL;DR: In this paper, a method to determine the output power, losses, and efficiency of induction motors, working in no-controlled conditions, in the presences of unbalanced and harmonics voltages, was presented.

TL;DR: In this article, a predictive tool for the energy consumption of wheat milling process using multiple linear regression and a new energy performance indicator (EnPI) is proposed This EnPI does not only consider the production of flour but also the particle size of flour and added water for softening wheat The results of the study, carried out in a wheat mill plant in Cuba, show a good coincidence between the predicted and real energy consumption.
