DYNAMICAL PROCESSES OF ELECTROMECHANICAL SYSTEMS OF MINING MACHINES IN MODES OF START AND STOPPING

There the mathematical description of processes of transmission and electromechanical transformation of energy in the drive of mining machine in the functioning field as the power transformer - the extended cable system - the induction motors - the components of mechanical transmitting device (transmission) - the actuator has been presented to study the dynamical processes of mining machines in the modes of start and stopping. The data about the observable and non-observable variables, about the static and dynamic characteristics of actuating induction motors of drives have been obtained on the basis of information which is contained in the forms and values of currents and voltages of their stator windings only. The quasi-optimum controls over the state of drive of mining machines have been synthesized. The developed study simulators of drive systems, the methods of specification and practical determination of characteristics of actuating motors of mining machines are used in the Research Institute of Explosion-Proof Electric Machines, Kemerovo.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
