“…A procedure to define the technical requirements of an EVT was presented in [124]; it was based upon a comparative study between the well-known Prius II and a virtual EVT-based HEV built with the same components and has shown comparable fuel consumptions [125]. The transmission efficiency of the DEP+DMP machine is higher than the magnetically-geared DRM [126]. The rules to choose the direct-drive speed also applies to DEP+DMP machines because the transmission efficiency decreases remarkably as the speed deviates from the direct drive point.…”

Distinct from the conventional machines with only one electrical and one mechanical port, electrical machines featuring multiple electrical/mechanical ports (the so-called multi-port electrical machines) provide a compact, flexible, and highly-efficient manner to convert and/or transfer energies among different ports. This paper attempts to make a comprehensive overview of existing multi-port topologies, from fundamental characteristics to advanced modeling, analysis, and control, with particular emphasis on the extensively investigated brushless doubly-fed machines for highly-reliable wind turbines and power split devices for hybrid electric vehicles. A qualitative review approach is mainly adopted but strong efforts are also made to quantitatively highlight the electromagnetic and control performance. Research challenges are identified and future trends are discussed.

“…However, the slip rings and brushes for conducting with inner wound rotor not only degrade the reliability, but also increase the maintenance cost and machine size [5]. Moreover, the thermal management of the inner rotor may be a big challenge due to the fact that the liquid cooling system is difficult or even impossible for the rotating inner rotor [6].…”

 -The magnetic-geared dual-rotor motor (MGDRM) has been proposed as a power split device (PSD) for several years, but there is not an evaluation work for a MGDRM in a real hybrid powertrain so far. As a pilot demo, a MGDRM-based hybrid powertrain with a real engine is built and tested in a real hybrid test bench. The closed-loop speed control is developed for the MGDRM, with which two pragmatic functions of the hybrid powertrain are realized by the MGDRM: Firstly, the engine can be started by the MGDRM outer rotor no matter the vehicle is parking or travelling. Secondly, the torque coordination function of the MGDRM can help the engine to stabilize at a fixed work situation. This feature is the basement to adjust the operation and efficiency of engine. The power conversion efficiency map of the MGDRM is tested, based on which, the performance of the power split in different operating situations can be evaluated.
