As the demand of electrical energy increases, it is vital to replace inefficient motors with new energy efficient ones. The first step towards achieving this goal is to estimate the existing motors efficiencies accurately to determine how much energy saving will be achieved by using energy efficient motors. This paper proposes an economical and accurate approach for motor field efficiency estimation...
The recent emphasis on energy conversion demands an improvement of the efficiency of three-phase induction motors (IM). The high efficiency IM can be achieved by selecting optimum motor design parameters. Therefore, it is necessary to develop an efficient evolutionary approach for optimal design of three-phase IM. This paper presents a bacterial foraging (BF) algorithm for optimizing the IM design...
Accurate efficiency estimation of in-service motor is crucial in industries for energy auditing and management. The method defined in IEEE Standard 112 cannot be used for in-service motors, because it disrupts the production process. This study presents a non-intrusive method for in-service motor efficiency estimation based on the bacterial foraging (BF) algorithm. The proposed method relies on measuring...
