Submitted: Jun 26, 2013; Accepted: Jul 24, 2013; Published: Jul 28, 2013 Abstract: A modern updating stage of an electromechanical energy converter, including the creation of power electromechanical systems with high-coercivity permanent magnets (PES with HPM), which comprise magnetic bearings on permanent magnets (MBPM) and hybrid magnetic bearings (HMB), puts forward an urgent scientific and ...

Physically, the coercivity of permanent magnets should scale with anisotropy field ferromagnetic compounds, HA; however, typical values commercial polycrystalline sintered are only ~0.2 HA, which is known as Brown’s paradox. Recent advances in multi-scale microstructure characterizations using focused ion beam scanning electron microscope (FIB/SEM), aberration corrected transmission microscopy ...

The advent of modern rare-earth permanent magnets, which have a magnetic energy product up to an order of magnitude greater than those of Alnico and ferrite magnets, with high remanence and coercive force, has resulted in improved performance of many devices and products. Modern rare-earth magnets, especially neodymium-iron-boron, when combined with technological advances in power and control e...

This paper deals with a way of computation of the mechanical behavior of Permanent Magnet synchronous couplings . This method is based on the calculation of the forces between the magnets of the device. The formulation of these forces is based on magnetic pole theory. The computation is done using a semi-numerical integration method. This method has been validated in test cases and appears to b...
