Abstract

Pulsed electromagnetic machines of shock action based on new vibro-impact technologies are widely applied in industry. Such machine striker mechanical vibrations frequency is equal to or multiple of the frequency of the supply network. The research purpose is the impact energy increase while pulse linear electromagnetic machine influence on a single-phase network power frequency is reduced. An improved version of a two-coil synchronous electromagnetic impact machine is considered, which involves dispersing the striking mass of a striker with electromagnetic forces in the forward and backward directions for a time equal to the duration of one voltage period. A new control method has been implemented to reduce the effect of the electric drive on the supply network by applying three half-wave voltages to the coils during the operating cycle time. With respect to the energy balance of the electromagnetic impact machine electromechanical system, the process of energy transformation for a full working cycle is considered, taking into account the interaction between all the elements of the impact unit. A mathematical model of the dynamics of a two-coil synchronous electromagnetic shock machine is proposed. The model is distinguished by the possibility of modeling interrelated electromechanical processes taking into account the nonlinearity of the characteristics of magnetic materials, the degree of mobility of inertial masses, the properties of elastic bonds and power losses. The computational algorithm is proposed together with an example of a numerical model in Matlab Simulink. Methods of mathematical modeling have confirmed the efficiency of the working cycle to improve the electromagnetic compatibility of the energy source with an electromagnetic shock unit
