Abstract: This paper presents a novel permanent-magnet electric variable transmission (PM-EVT) with
an appropriate structure for hybrid electric vehicle (HEV) applications. Such a PM-EVT is similar to the wellknown
series-parallel HEV (SP-HEV) of Toyota Prius, but with more integrated functions and simpler structures,
with the planetary gear also eliminated. By analyzing four possible mechanical connections and different PM
positions, a simplest structure of PM-EVT was finally chosen which has one stator, one inner rotor and one
outer rotor, with the stator and inner rotor having independent windings, and the PMs located on the outer rotor.
The results show that different PM arrangements on the outer rotor regard the machine performances and
controllabilities.

Key words: hybrid electric vehicle (HEV), electric variable transmission (EVT), permanent-magnet machine
