Computer Modeling of the Dynamic Processes for Stepping Motor
The issues concerning the dynamic processes of the digital modeling for variable reluctance stepping motor were investigated. The differential equations for two – phase motor are presented on the bases of which the model of the stepping motor was compiled as well as the block diagram of it was obtained.The differential equations characterize the change of the currents in the windings of the analyzed motor and are derived from the equations of the voltages balance. The model of the dynamic processes was compiled in the modern system of Matlab/Simulink system. The submitted model is available for the research of the transitional processes and dynamic characteristics of the stepping motor, when only one control impulse is supplied into the windings of the stator or when a certain series of control impulses are supplied into. The obtained results indicate that at the very beginning of the step there are processes of the stator currents, speed of the rotor, oscillation processes of the electromagnetic torque, which are determined by the energy changes between the motor and control system.
