Abstract
The paper presents a number of advanced solutions on electric machines and machine-based systems for the powertrain of electric vehicles (EVs). Two types of systems are considered, namely the drive systems designated to the EV propulsion and the power split devices utilized in the popular series-parallel hybrid electric vehicle architecture. After reviewing the main requirements for the electric drive systems, the paper illustrates advanced electric machine topologies, including a stator permanent magnet (stator-PM) motor, a hybrid-excitation motor, a flux memory motor and a redundant motor structure. Then, it illustrates advanced electric drive systems, such as the magnetic-geared in-wheel drive and the integrated starter generator (ISG). Finally, three machine-based implementations of the power split devices are expounded, built up around the dual-rotor PM machine, the dual-stator PM brushless machine and the magnetic-geared dual-rotor machine. As a conclusion, the development trends in the field of electric machines and machine-based systems for EVs are summarized.
Highlights
In recent decades, the rapid increase in the amount of vehicles in use has seriously impacted on worldwide energy consumption and environment

hybrid excitation FSPM motor (HEFS) inherits the advantages of the flux switching PM motor (FSPM) motor, namely the bipolar flux linkage, the sinusoidal back-electromotive force (EMF) waveform and the easy modular manufacturing; it has the merits of a simple flux control and a remarkable efficiency for operation at high speeds
Summary
The rapid increase in the amount of vehicles in use has seriously impacted on worldwide energy consumption and environment. Different from the ICE vehicles, EVs have an electric motor embedded in the powertrain. Electric machines, electric drive systems and individual mechanical devices are the key technologies of an EV/HEV powertrain. Individual mechanical devices, like the power split, play a crucial role in HEVs with the popular series-parallel architecture, and their operation directly influences the achievement of the driving efficiency goals. The purpose of this paper is to present a number of advanced solutions on electric machines, electric drive systems and the implementation of the power split devices by means of electric machines.
