Single-Phase Induction Motors and the Challenge of Energy Efficiency in Brazil: a Critical and Proposed Analysis

EasyChair Preprint 14584

Abstract

There is a global effort to optimize energy use and reduce the con-sumption of fossil fuels, aiming to decrease greenhouse gas emissions as a strategy for mitigating climate change. One way to improve this situation is by addressing the demand side, such as regulating trade and producing ener-gy-consuming equipment. Among the devices that consume the most electric-ity are electric motors, which use about half the electricity available in indus-trialized countries. Some countries have already included single-phase electric motors in their Minimum Energy Performance Standards (MEPS). Single-phase motors are commonly used in applications where, three-phase motors are limited and the power demand is typically lower, such as in residential, ru-ral, commercial, and service settings. Despite the significant market presence of this type of motor in Brazil, with approximately 55 million units consumed in 2019, Brazil has not yet implemented MEPS for single-phase motors. Con-sidering this context, this study aims to evaluate the possibility of including MEPS for single-phase motors in Brazil in three stages. Firstly, i) a literature review of MEPS for single-phase motors worldwide was conducted. Subse-quently, ii) an evaluation of 25 single phase motors from 11 different manu-facturers that are sold in Brazilian market was done to check how was the ef-ficiency level of these motors. iii) a proposal for the adoption of MEPS for sin-gle-phase electric motors in Brazil is presented. Additionally, lastly iv) an es-timate of energy savings from the implementation of MEPS for single-phase motors in three scenarios over a 30-year horizon is presented.
