Abstract-Over the last decade, forced regulations and a growing social awareness with respect to energy efficiency have resulted in a renewed interest in the research for high efficient electrical machines. When an electrical motor is coupled to a machine, in many cases a gearbox or belt transmission is used.Research shows a lack of information on energy efficiency of these components. In comparison to electrical motors and drives, there is very few regulation and if efficiency values can be found in catalogues, there is no regulated test procedure available to validate the data. As a result, the reliability of these efficiency values is unknown and comparison between manufacturers and technologies is impossible. In this paper a test bench is proposed to measure the energy efficiency of a gearbox with an accuracy up to 0.4%. The test bench is used to measure the efficiency of gearboxes in their entire speed and torque range. Contour maps are used to visualize these measurement results. Moreover, a measurement campaign using different gearboxes is carried out to compare the energy efficiency in the manufacturers catalogue and the measured efficiency.

Line-start synchronous machines (LSSMs) emerged as an efficient alternative for induction machines in numerous constant speed applications. This study reviewed evolution, technological advancements, design concepts, optimisation techniques, and possible applications in a comprehensive manner. A case study on the reviewed LSSM has been carried out based on its suitability in agricultural applications in India. Further, the performance comparison and significant advantages between the existing induction machine and LSSM are finally discussed.

This paper analyzes the effects of voltage harmonic distortion on the losses and efficiency of energy efficient induction motors (EEIM). Preliminary studies show that when fed with distorted voltages the new EEIM have a greater impact on efficiency than standard induction motors. Therefore, in this work a more precise steady state equivalent circuit is used to quantify accurately the impact of the distorted voltage waveform on losses and efficiency of induction motor. The model is validated using two induction motors both of 5.5kW, 50Hz, four poles; one is class IE3 Premium efficiency and the other is class lE1 standard efficiency. The analysis of the results may lead to infer that the EEIM are a good alternative to reduce energy consumption, but the margin is lower under fed with distorted voltages compared with ideal supply conditions.
