Research of Change of Parameters of a Magnetic Flux of the Stator and Rotor of Special Electric Drives

Abstract

Research, design, simulation and creation of electric actuators of different constructions including special electric actuators, is quite difficult and multidimensional task. One of the main objectives in case of a research and simulation of such electric actuators is determination of electromagnetic parameters which correctness of determination depends on complexity of a mathematical model and accuracy of the used mathematical apparatus. One of required electromagnetic parameters on which the correctness of a research and design of special electric actuators with asynchronous engines depends is the magnetic flux. The complexity of determination of a magnetic flux is that there is the continuous change of both the temporal, and spatial parameters influencing the instantaneous value of the researched value. In article the problem of definition of a magnetic flux from the electromagnetic field created by a stator winding is considered and solved. The formed electromagnetic field creates a magnetic flux from a rotor winding. The total electromagnetic field in a gap of components of special electric drives is as a result formed. For the solution of this problem was the programs of calculation allowing to receive for various angles of rotation of vectors of three-phase system of tension pictures of a real magnetic flux from the stator and a rotor of special electric drives are developed.
