Energy harvesting from electric power lines employing the Halbach arrays

Review of Scientific Instruments, 2013
This paper proposes non-invasive energy harvesters to scavenge alternating magnetic field energy from electric power lines. The core body of a non-invasive energy harvester is a linear Halbach array, which is mounted on the free end of a piezoelectric cantilever beam.

Research and simulation of an improved Halbach arrays

2011 International Conference on Electric Information and Control Engineering, 2011
Halbach array is new permanent structure. It was proposed by physicist Dr. K. Halbach of the U.S. Lawrence Berkeley National Laboratory. This paper proposes an improved magnet structure of Halbach array. By simulation of finite element software-Ansoft's Maxwell, the results show that improved magnet structure can effectively improve the uniformity of ...

Partitioned stator flux reversal machines having Halbach array PMs

2015 IEEE Magnetics Conference (INTERMAG), 2015
Purpose – In this paper, the partitioned stator flux reversal permanent magnet (PM) (PS-FRPM) machines with Halbach array PMs are investigated to compare with the machine having the conventional parallel magnetized PMs, and conventional FRPM machine. This paper aims to discuss these issues.
