Research of an electromagnetic vibrator with a non-linear power supply

Abstract Electromagnetic vibration exciters (EMW) are widely used in various sectors of the national economy (chemical, mining, engineering, oil and gas) for transportation and simultaneous processing of bulk cargo, mixing and batching, grinding, separation, etc. Recently, more and more attention has been paid to the problems of their automation. This is caused by the fact that controlled vibration machines can significantly increase and stabilize at a given level of technological processes. Automation of EMVV can be solved only by developing automatic stabilization of performance with closed feedback. Rational design of this kind of sustainability needs theoretical justification. This article discusses the analysis of self-oscillations in electromagnetic exciters with a nonlinear power source used in vibration technology. To analyze the equations, the averaging method was used. Using this method allows obtaining periodic solutions for current and mechanical vibrations. The results of the analysis can be used in the development of self-oscillating electromagnetic exciters.
