Research of the Electromagnetical Part of Three-Phase Electromagnetic Vibrator of Low Frequency Vibrations

Abstract

It is known that the stable operation of existing three-phase low mechanical frequency electromagnetic type vibrating devices depends on keeping the specific frequencies of the electrical and mechanical systems at the same value or close to each other. In the work process, the specific frequency of the mechanical system is variable depending on the mass, while the specific frequency of the electrical system remains practically constant. This causes unstable operation of the electromechanical system of the vibration device. In order to overcome this deficiency, the article considers the issue of expanding the frequency interval of the amplitude-frequency characteristic of the electrical system.
