Design of permanent magnets to chaoize doubly salient permanent magnet motors for electric compaction

This article proposes and implements a class of chaotic motors for electric compaction. The key is to develop a design approach for the permanent magnets PMs of doubly salient PM DSPM motors in such a way that chaotic motion can be naturally produced. The bifurcation diagram is employed to derive the threshold of chaoization in terms of PM flux, while the corresponding phase-plane trajectories ...

The Impact of the Selection of Permanent Magnets on the Design of Permanent Magnet Machines – a Case Study: Permanent Magnet Synchronous Machine Design with High Efficiency

Considering that the natural sources of the earth are limited, it is necessary to produce economical electrical machines with a high efficiency through better design and a proper selection of materials. At present, magnets have a high energy product (BHmax) with suitable magnetic and physical properties for applications in electrical machines. This paper considers how an electrical engineer cou...

Permanent magnets and hard magnetic materials

After discussing the fundamental properties of all hard magnetic materials, based on the intrinsic and extrinsic properties, some remarks on the history of hard magnetic materials and permanent magnets are given. The important hard ferrites are only b...

Rare earth elements and permanent magnets (invited)

Rare earth (RE) magnets have become virtually indispensible in a wide variety of industries such as aerospace, automotive, electronics, medical, and military. RE elements are essential ingredients in these high performance magnets based on intermetallic compounds RECo5, RE2TM17 (TM: transition metal), and RE2TM14B. Rare earth magnets are known for their superior magnetic properties—high inducti...
