Abstract
Objectives: The main purpose of this study is to investigate switched reluctance motor for E-rickshaw propulsion system. Methods: The paper gives details of Literature review of current system incorporated in electric three wheeled propulsion, selection process of SRM, the design procedure of 8/6, 48V, 0.5 kW, 2000 rpm Switched reluctance motor for E-Rickshaw. Design validation and performance estimation is done by virtue of finite element analysis (FEA) tool using Ansys Maxwell Software. Findings: In this present work we found that it is possible to deploy SRM instead of current existing brushless direct current motors (BLDC) and PMSM (Permanent magnet synchronous motors) which are used in power train of electric three wheelers. Incorporating SRM would boost to promote “MAKE IN INDIA” and thus the country would become independent in electric vehicle market, hardware of the proposed SRM is also developed and tested. Novelty: The work done with investigation of SRM for E-rickshaw has not been studied until now although it possesses various advantages over existing system like high reliability and wide torquespeed range which is the basic requirement of propulsion motor in electric vehicles. SRM also provides several benefits like simple construction, high speed, resilience and good fault tolerance capability as all phases function independently. Keywords: ERickshaw; Brushless direct current motors; finite element analysis; Ansys Maxwell Software; Switched reluctance motor; Make in India
Highlights
A days there is a proliferation in the sector of electrification of vehicles especially 3-Wheelers as it is the most efficient mode of transport for “Last-Mile connectivity”
This paper is arranged in following way: section II focuses on modeling of SRM, section III discusses the selection of switched reluctance motor, section IV deals with design approach of SRM for E-rickshaw, section V includes simulation results and section VI has concluding remarks
Mathematical model has been developed and it is compared with the simulation results carried out from Ansys Maxwell software which is a finite element analysis (FEA) tool
Summary
A days there is a proliferation in the sector of electrification of vehicles especially 3-Wheelers as it is the most efficient mode of transport for “Last-Mile connectivity”. In comparison with other motors, SRM has independent phases so, if a fault occurs to any of its phases, the motor and its drive are capable to carry on with the operation but with decreased power output.(8) But still SRM has got some disadvantages like high torque ripple, high noise, vibrations and necessity of position sensor. It requires better, modern control strategy than AC and DC motor drives.(9). This paper is arranged in following way: section II focuses on modeling of SRM, section III discusses the selection of switched reluctance motor, section IV deals with design approach of SRM for E-rickshaw, section V includes simulation results and section VI has concluding remarks
