Telyuta R. Resource and energy saving modes of the system induction motor - working machine in agriculture.

Object - process of transformation of energy in the asynchronous electric motor. The purpose - increase operational indicators works asynchronous electric motors and reduction of losses of active energy in system "the electric motor - the working car" at the expense of use of electromechanical control systems on the basis of developed resource and energy saving operating modes. Methods - a symbolical method of the analysis of electric chains, a method of circular diagram's, a method of symmetric making pressure and currents, methods of the analysis of linear electric chains. Novelty - has had the subsequent development the theory of losses of active energy in the asynchronous electric motor with a short-circuited rotor with specification of an equivalent circuit of a phase of the engine and the account of growth of active resistance of conductors of a winding at heating. For the first time definition of losses of active capacity in the electric motor by use of the circular diagram of a complex of a total power as electric motor sliding is offered. The theory of losses active energy in the asynchronous electric motor of a drive of the working car taking into account factor of loading of last, level of pressure, symmetry of a food has had the subsequent development. For the first time the factor of losses of active energy and expenses of a resource of isolation as integrated criterion resource and energy saving operating modes of asynchronous electric motors is offered. Results - the mathematical model resource and energy saving and the device of functional diagnosing of operating modes of system "the electric motor - the working car" is developed. Branch - an agricultural production.
