Book Synopsis Surface Investigations on Permanent Magnets by : K. J. Kronenberg
Download or read book Surface Investigations on Permanent Magnets written by K. J. Kronenberg and published by . This book was released on 1963 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnets of iron, cobalt and iron-cobalt particles were made with different matrix materials. Magnets pressed from a gel of magnetic particles and mercury were used to evaluate the progress of the various phases of the process. These magnets are commonly referred to as ''mercury matrix'' magnets. In order to eliminate the mercury these magnets were distilled at high temperatures under a vacuum. This resulted in the production of porous blocks of fine particles which were either vacuum impregnated with resins or crushed, mixed with binder and repressed. Lead was added to the heat treated gel before pressing. These magnets were distilled, crushed and repressed. Magnets were made by superficially oxidizing submicron particles of iron-cobalt. Gross structure in fine particle magnets was revealed by electron micrographs.

Book Synopsis Manganese-Aluminum for Permanent Magnet Material by : M. A. Bohlmann
Download or read book Manganese-Aluminum for Permanent Magnet Material written by M. A. Bohlmann and published by . This book was released on 1963 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manganese-aluminum alloys with 68-73% Mn were developed for permanent magnet material. Best magnetic properties were obtained in 71% Mn alloys. Maximum energy product was 4.0 x 10 to the 6th power GOe, reached by homogenization, controlled quenching, reducing area 86% by swaging in jackets, and annealing. Process parameters were studied to fine the optima for the brittle alloy. Deformation of the alloy produces a preferred magnetic axis and raises coercive force. Swaging was best, but deforming by turning cast bars into chips on a lathe gave the best ''particle'' magnets and was easiest. A review of the crystal and magnetic structures leads to the deduction that dislocation lines involve Mn atoms arranged antiferromagnetically which subdivide larger ferromagnetic regions. The magnetic saturation is not reached in practical magnetizing field. The magnetic induction decreases with increasing temperatures to Curie point.

Book Synopsis NMR Methods for the Investigation of Structure and Transport by : Edme H Hardy
Download or read book NMR Methods for the Investigation of Structure and Transport written by Edme H Hardy and published by Springer Science & Business Media. This book was released on 2011-10-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods of nuclear magnetic resonance (NMR) are increasingly applied in engineering sciences. The book summarizes research in the field of chemical and process engineering performed at the Karlsruhe Institute of Technology (KIT). Fundamentals of the methods are exposed for readers with an engineering background. Applications cover the fields of mechanical process engineering (filtration, solid-liquid separation, powder mixing, rheometry), chemical process engineering (trickle-bed reactor, ceramic sponges), bioprocess engineering (biofilm growth), and food process engineering (microwave heating, emulsions). Magnetic Resonance Imaging (MRI) as well as low-field NMR are covered with notes on hardware. Emphasis is placed on quantitative data analysis and image processing.
Book Synopsis Permanent Magnet Synchronous Machines by : Sandra Eriksson

Available in PDF, EPUB and Kindle. Book excerpt: Interest in permanent magnet synchronous machines (PMSMs) is continuously increasing worldwide, especially with the increased use of renewable energy and the electrification of transports. This book contains the successful submissions of fifteen papers to a Special Issue of Energies on the subject area of “Permanent Magnet Synchronous Machines”. The focus is on permanent magnet synchronous machines and the electrical systems they are connected to. The presented work represents a wide range of areas. Studies of control systems, both for permanent magnet synchronous machines and for brushless DC motors, are presented and experimentally verified. Design studies of generators for wind power, wave power and hydro power are presented. Finite element method simulations and analytical design methods are used. The presented studies represent several of the different research fields on permanent magnet machines and electric drives.
