ABSTRACT: As a topology of novel brushless permanent
magnet (PM) machines, stator-PM brushless machines having
magnets and armature windings in stator (the so-called
stator-PM machines), exhibit the merit of convenient heat
dissipations. The compact and robust rotor structure also makes
stator-PM machines potential candidates for high speed
applications. Meantime, the air-gap flux regulations can be
realized by hybrid excitations of PMs and field windings,
which consequently expands the speed adjustment regions.
Overall, the stator-PM machine features the definite advantages
of robust structure, high power density and efficiency, high 0
fault-tolerant capability and being applicable of various control
strategies. In this paper, a comprehensive and systematical
overview on the stator-PM brushless machine systems and their
key technologies is conducted, with particular emphasis on
machine topologies, operation principles, design and analysi
