Economic evaluation of induction motor based on motor’s nameplate data and initial cost

This paper presents a practical approach to calculate the total owning cost (TOC) of three-phase Induction Motor, which is based on motor’s nameplate data and purchasing price. The economic evaluation performed considering both induction motor electrical energy losses its amortized annual capital cost. proposed technique consists three stages, where power are determined analytically in first stage. load loss factor (LSF) statistically obtained determine second In third stage, was conducted. results show that helpful tool for decision-maker when comparing received offers from different vendors finding answer question offer has less TOC. Finally, method illustrated through numerical example software using MATLAB performed. Results conclusions have been summarized discussed.
