Моh'd Z. Establishment of interrelation between geometrical and power parameters of electric apparatuses with the purpose of rational selection of apparatuses and their series

Object – electric apparatuses. Objective – establishment of dependences of power and electromagnetic parameters of electric apparatuses from their geometrical sizes for development of criterion of rational choice of apparatuses and their series. Methods – theories of electric apparatuses, theories of electromagnetic field, probability theory and mathematical statistics, theory of errors, mathematical modeling. Devices – industrial electrical apparatuses. Novelty – analytical dependences of electromagnetic parameters of the electric device on the generalized linear size are received, the parameter "factor of losses of power" is offered and proved, character of dependences of power parameters of various electric apparatuses from the generalized linear size is specified. Results – the criterion of a rational choice for separate models of apparatuses of the identical power, giving an opportunity to compare electric apparatuses only on their geometrical sizes and weight is offered, the criterion of a rational choice of series of electric apparatuses is offered. Implementation – in design work of scientific research institute UktNDIVE for a choice of optimum ratio at designing electric apparatuses and in manufacture of electric apparatuses on Lugansk electrohardware factory for an estimation of a level of made electric apparatuses. Sphere of application – theory of electric apparatuses, electromechanics, electrical engineering.
