Sizing and Performance Analysis of an Electric Motor in an E-rickshaw

Abstract

In the current world of modernisation, the quantity of fossil fuels and petroleum products are tremendously decreasing. Here comes the relevance of Electric Vehicle (EV) due to the available renewable electrical energy sources, effective regenerative braking, improved road handling, and torque top-up capability. Nowadays BLDC motor is commonly used in EV, but due to its vibrations, noise, and high torque ripples PMSM is a better replacement for BLDC in EV applications. Among the EVs, auto-rickshaws and E-rickshaws are the normal vehicles for common people. For E-rickshaws, PMSM can be selected since it exhibits high efficiency, high output torque, and small in size due to its high power density. The construction of PMSM for an E-rickshaw involves a lot of design specifications and calculations. Before the physical construction of PMSM, it is necessary to realize that the designed machine exhibit better performance for EV application. In order to verify these, a virtual development and performance analysis of PMSM is necessary. This paper proposes sizing with vehicle dynamics, analytical design, virtual development, and performance analysis of a three-phase PMSM using Finite Element Analysis (FEA) in Ansys Maxwell platform. The electrical and magneto-static analysis are also included in this paper.
