The lattice equivalent circuit of the DC motor in mine lift-and-carry transfer mechanisms

Authors: Blanc A. V.

In the mining industry, DC motors are widely used, so analyzing and simulating the electromagnetic fields are of great importance. The numerical-based computer programs solving the field equations are most often used for simulating the electromagnetic fields. At the same time, such analytical methods are still in demand, which can be considered as a kind of numerical methods, since in practice they are difficult or completely impossible without computers. The lattice equivalent circuits are these methods for calculating and modeling the electromagnetic fields. The lattice equivalent circuit is based on the fundamental laws of the electromagnetic theory (Ampere’s circuital law and Faraday’s law of electromagnetic induction). It is the complicated electric circuit with active and reactive elements, in which the vector magnetic potential components are the analogues of the voltages and the vector components of the magnetic field intensity are the analogues of the currents. This paper tells about the lattice equivalent circuit of the DC motor, which is part of the drive of the liftand-carry transfer mechanism for the mine electric equipment. In the DC motor, the stator is salient-pole and the rotor is cylindrical. The stator poles and rotor teeth have the constant magnetic permeability. The exciting current and the currents of the rotor slots are the initial data of the problem. The electromagnetic field is modeled within the double pole pitch for a certain fixed point of time. Test calculations indicate a rather high accuracy of the lattice equivalent circuit of the DC motor.
