TLDR
In this paper, a global analysis of the potential energy savings which could be found in electric motor-driven system (EMDS) is presented, and a comprehensive package of policy recommendations to help governments achieve these significant energy savings in EMDS is proposed.Abstract:
This paper is the first global analysis of the potential energy savings which could be found in electric motor- driven system (EMDS). EMDS currently accounts for more than 40% of global electricity consumption. Huge untapped energy efficiency potential was found in EMDS; around 25 % of EMDS electricity use could be saved cost-effectively, which would reduce total global electricity demand by about 10%. To date, energy efficiency opportunities with EMDS have been relatively neglected in comparison with other sustainable energy opportunities. It is crucial to scale up operations and resources committed to realizing the vast potential energy savings and this paper proposes a comprehensive package of policy recommendations to help governments achieve these significant energy savings in EMDS.read more

Approximation of Permanent Magnet Motor Flux Distribution by Partially Informed Neural Networks
TL;DR: It is demonstrated that the proposed modified ELMs are suitable for modeling motor flux versus position and current, especially for interior permanent magnet motors, and the proposed approach produces more accurate models and provides greater robustness against learning data noise.

Geometrical control of eddy currents in additively manufactured Fe-Si
TL;DR: In this paper , a hexagonal pattern was proposed to limit the eddy current loss in high-frequency electrical machines. But the performance of the proposed cross-sectional designs was limited by the fact that the cross-sections are complex and there are defects in these complex cross sections causing increased eddy currents.

Measuring structure functions of power devices in inverters
TL;DR: The novelty in this work is the methodology used to achieve the measurement of the cooling curve and obtaining the structure function despite issues related to freewheeling current due to energy stored as a result of motor inductance.

Effect of Femtosecond Laser Impulses for Metallic Glass Magnetic Properties during Laser Cutting Processes
TL;DR: In this article, different femtosecond laser cutting parameters are presented, as well as, the results of the samples magnetization after the cut, so the microstructure and the surface of the cutting side do not change.
