Abstract

Revenues from global sales of light electric vehicles are expected to grow from $ 9.3 billion in 2017 to $ 23.9 billion in 2025. In order to boost this growth electric drives with better features and lower costs have to be developed. This paper presents a new in-wheel axial-flux switched reluctance motor with double rotor and a particular disposition of the stator and rotor poles that provides short flux path without flux reversal. The magnetic active parts of the stator and the rotor are built using soft magnetic composites. The motor is fed from batteries trough a on purpose designed electronic power controller. Simulation of the whole drive, using Matlab-Simulink coupled with the results of the three dimensional finite analysis of the motor is carried out. Simulation results prove that the proposed in-wheel axial-flux switched reluctance motor drive is adequate for the propulsion of electric light vehicles.

Abstract

Electrification of road vehicles is one of the most consistent initiatives to achieve a clean, environmentally friendly and efficient transport system. The choice of the electric machine for the powertrain is an important consideration, nowadays tilted towards permanent magnet synchronous machines. However, rare earth permanent magnet supply drawbacks open up new prospects for other types of machines, such as switched reluctance machines (SRM). This Workshop, Switched reluctance motor drives an alternative for E-traction, aims to deepen into the potential of SRM for electric traction, to be a meeting point for groups that are currently working on the development of SRM drives and an opportunity to establish future collaborations. The Workshop consists of two parts. In the first part, participants will present papers about issues related with switched reluctance machines for electric traction applications. In the second part, they will discuss what aspects slow down the application of SRM drives for electric traction and their possible solutions.

Electrification of road vehicles is one of the most consistent initiatives to achieve a clean, environmentally friendly and efficient transport system. The choice of the electric machine for the powertrain is an important consideration, nowadays tilted towards permanent magnet synchronous machines. However, rare earth permanent magnet supply drawbacks open up new prospects for other types of machines, such as switched reluctance machines. The Workshop aims to be a meeting point for groups that are currently working on the development of Switched Reluctance Motor drives (SRMD) and an opportunity to establish future collaborations. The Workshop consists of two parts. In the first part, in the morning, participants, all by invitation, will present new types of switched reluctance machines for electric traction applications. In the second part, in the afternoon, all participants will discuss what aspects slow down the application of SRMD for electric traction and their possible solutions.
