Approach of vibration rendering on the basis of electrical power balance

In the practice of testing materials, separate parts, constructions utilized in mechanical engineering, widely adoption got vibration test, often in the wide range frequency. From economical point of view drive and realization of stable frequency and amplitude of judder with some advantage has a manageable electromagnet vibration system. Lately, because of development of semiconductor equipment, there is an opportunity of creating more effective manageable systems in terms of electromagnet vibration exciters.
