In the present, unmanned aerial vehicles (UAV) has arisen more and more attention due to the high efficiency, ease and safety in completing complex missions [1][2].
Soft magnetic composite (SMC) material is a new soft magnetic material, now it is popular in the designing of permanent magnet machine where high operation frequency and 3-D flux path required, due to its advantages of low eddy current loss and magnetic isotropy.
Compared with three-phase SRM, multi-phase SRM is higher power density and lower torque ripple. However, with phase number increasing, the requirement of power converters for multi-phase SRM such as using less power devices and independence between phases are enhanced. In this paper, six kinds of power converters for six-phase SRM are investigated and compared including asymmetric half bridge (AHB)...
Soft magnetic composite (SMC) material is a relative new soft magnetic material which has undergone the substantial development during last decades. Especially with the low-pressure pressing on the mold, the magnetic core with SMC of the machine can be fabricated easily and the manufacture cost can be reduced greatly. By using this technology, a claw pole machine (CPM) with SMC core was designed and...
With the great concerns on alleviating the pollution on the environment and traffic congestions; there is a trend for developing the electric vehicles [1], [2]. For such drive system, the in-wheel machines draw the main attention due to its relative higher torque density and compact structure [1]. With the permanent magnet (PM) located on the stator teeth, the flux switching permanent magnet machine...
The particle swarm optimization (PSO) is an alternative for global optimization. A standard for PSO (SPSO) was defined which took into the latest developments, and was used as a baseline for performance testing of improvements. In SPSO, however, particles need to search the optimal solution in the constraint space, and the item velocity in PSO makes particles difficult to adjust themselves to meet...
