Permanent-Magnets Linear Actuators Applicability in Automobile Active Suspensions

Linear Transverse Flux Reluctance Machine with Permanent Magnets

A new structure of linear transverse flux machine (TFM) is presented in this paper. It is in fact a variable reluctance linear machine having permanent magnets on the mover. Its structure and its working principle will be discussed. After a preliminary design of the motor a 3D FEM analysis was carried out before optimizing the designed linear motor. The flux densities in the machine and the sta...

Advances in nanostructured permanent magnets research

This paper reviews recent developments in research in nanostructured permanent magnets (hard magnetic materials) with emphasis on bottom-up approaches to fabrication of hard/soft nanocomposite bulk magnets. Theoretical and experimental findings on the effects of soft phase and interface conditions on interphase exchange interactions are given. Synthesis techniques for hard magnetic nanoparticle...

Homopolar Permanent-Magnet-Biased Actuators and Their Application in Rotational Active Magnetic Bearing Systems

Active Magnetic Bearings (AMBs) are already widely used in rotating machinery and continue to gain popularity due to the ever-present push to higher rotational speeds and decreasing prices of associated electronic components. They offer several advantages over conventional mechanical bearings including non-contact rotor support (thus eliminating mechanical wear and the need for lubricants), abi...
