Fauzi M. Increase of efficiency of application electromagnetic pulleys for separation

Object - a pulley with electromagnetic excitation for magnetic separation; the purpose increase of efficiency of magnetic pulleys by optimization consumption of energy in an operating conditions, by a rational choice of geometrical and electric parameters of their elements of a design on the basis of improvement of a technique of design calculations in view of conditions of magnetic separation of loose materials on tape conveyors; methods of mathematical modelling of processes in electric devices, the theory of magnetic separation, a method of secondary sources, numerical calculation of system of the transcendental equations; novelty - the advanced mathematical model of processes of magnetic separation in a working zone of a pulley, expression for calculation of force pulling a magnetic field is received analytical in view of influence on this force of the sizes of a body and poles, their relative distance, necessary force of pulling a pulley of any standard size is determined in view of conditions ofmagnetic separation, the technique of definition of rational values of geometrical and electric parameters of a pulley with minimal consumption of energy is advanced, analytical ratio between the basic geometrical sizes of a pulley of a standard size 65 - 63 and its specific force of pulling are received; results - the technique of synthesis of parameters double-pole an electromagnetic pulley is offered, which provides a minimum consumption of energy, sufficient for reliable magnetic separation of a loose material, transported by the tape conveyor under known conditions of operation; a degree of implementation - a design procedure; sphere of use - technologies of processing of the loose materials, demanding magnetic separation Area of use - manufacturing of electric apparatus.
