“…It is highly possible that electric bicycles (e-bikes) and electric scooters (e-scooters) are to replace the combustion engine motorcycles. The global market of e-scooters is expected to increase from 4.1 million in 2015 to over 4.4 million in 2025, with the largest gains expected in India, Indonesia, and Vietnam [39].…”

A Model for Sustainable Courier Services: Vehicle Routing with Exclusive Lanes

et al. 2020

In Southeast Asian cities, it is common for logistic companies to operate a heterogeneous fleet of delivery vehicles with motorcycles being the preferred vehicle to handle the final phase of delivery. In such scenarios, heterogeneous fleet vehicle routing problem (HFVRP) is generally applied to plan an optimal delivery. However, in many downtown cores of large and rapidly developing Southeast Asian cities, HFVRP is neither viable nor reliable because of road usage restrictions. The purpose of this article is to develop and test a different approach that accurately takes these restrictions into account and provides viable and more sustainable results. Restrictions in this paper refer to situations of urban areas in Vietnam where (i) certain vehicle types are prohibited in specified areas or where narrow alleyways limit the utilization of vehicles that exceed the road capacity and (ii) certain roads are exclusive to certain vehicle types. In networks, limited access and exclusive lanes are represented as links, or arcs, exclusive to one or another. Taking these limitations into consideration, we have developed a unique model, which we have termed Vehicle Routing Problem with Exclusive Links (VRP-EL). The model was validated and tested for its performance on scenarios with varying ratios of exclusive links. Scenarios up to 500 customers were tested on a meta-heuristic algorithm, simulated annealing. VRP-EL produces realistic outcomes. Limiting certain links to be selected according to vehicle types increases overall travel distance. However, this increase outweighs the cost of re-planning and rerouting had they not been constrained initially. The reduction in traveling distance leads to fossil fuel reduction for the overall system. The estimation of reduced carbon emissions through applying the proposed model is presented. Considering the severe traffic congestion and carbon emissions caused by motorcycles in Vietnam, the proposed model leads to a sustainable road environment.

“…Aunque en el estudio presentado la máquina seleccionada es el accionamiento SRM cuyas características se muestran en el apéndice con control de histéresis a bajas velocidades y control de pulso único para elevadas velocidades, se han realizado exhaustivas pruebas experimentales sobre otros accionamientos SRM de distinto tamaño [20] y de diferente configuración [21], en los que se han utilizado las diferentes técnicas de detección indicadas en la sección III, llegándose a la conclusión de que las técnicas más adecuadas para el caso de los accionamiento SRM son: el análisis de la corriente y el análisis espectral de la aceleración de la vibración.…”

In a near future when Industry 4.0 is implanted, predictive maintenance will have a much more prominent role than that currently plays in traditional industry. Predictive maintenance is the organized monitoring with periodic or continuous measurement of variables of the state of the equipment to be maintained and its comparison with preestablished patterns for the determination of the instant in which the maintenance intervention should take place. Three-phase induction motor drives are one of the industrial equipment that has been given greater attention regarding predictive maintenance plans. In recent years, switched reluctance motor drives have begun to have some relevance in the industry. In this paper, after a brief review of the switched reluctance motors and their control, an analysis of the different types of faults and a description of the most usual diagnostic techniques in electric drives, a predictive maintenance plan for switched reluctance motor drives is proposed. This predictive maintenance plan considers different control strategies (hysteresis and single pulse), and is based on diagnostic techniques such as analysis of currents and spectral analysis of vibrations. Exhaustive experimental tests have been carried out in order to validate the proposed plan.

“…In a previous paper electromagnetic analysis of the double rotor AFSRM was performed using 2D FEM taking 2D planes of the machine geometry in several radiuses, transforming the axial-flux machine in a linear machine [9]. Thus the internal electromagnetic torque can be determined, in the case of considering the section corresponding to the average radius, by calculating the force of translation (x direction) of the resulting linear machine and multiplying by the mean radius.…”

“…As a first control option the hysteresis control with variable turn-on and turn-off angles until 600 rpm and single pulse with variable turn -on turn-off angles for upper values of speed although the need for reduced torque ripple surely will require instantaneous direct torque control. The simulation was performed using Matlab-Simulink considering the results of the previous 3D FE analysis as was described in [9]. The simulation results allow obtaining the waveforms of the electrical magnitudes of the drive, as well as the internal electromagnetic torque.…”

Abstract.In this paper, a novel in-wheel double rotor axialflux switched reluctance motor for electric traction is presented. The proposed double rotor axial-flux switched reluctance motor has a particular disposition of the stator and rotor poles that provides short flux path without flux reversal. The ferromagnetic pieces of the stator and the rotor are built using soft magnetic composites. Electromagnetic analysis is performed using three dimensional finite element analyses, 3D FEA. Matlab-Simulink simulation coupled with the results of finite element analysis proves that the proposed motor drive is suitable for the propulsion of a given E-scooter.
