New linear synchronous cycle electromagnetic machines with inertial reverse

Abstract

Impact impulse linear electromagnetic machines are widely used in new vibratory impact technologies It is necessary to increase impact energy and decrease impulse linear electromagnetic machine influence on a single-phase power-line. This is an actual problem to be solved by developing perspective operating cycles and control algorithms. The paper states a new variant of two-inductor impact synchronous electromagnetic machine. The head impact mass is accelerated back and forth by electromagnetic forces. The newly-developed operating cycle is considered with an example of the two-inductor impact electromagnetic machine with inertial head reverse where the control method is protected by the patent. This method permits to reduce electric drive influence on the power-line. The energy conversion process over total operating cycle is described with the electromechanical system energy balance with respect to interaction between all elements of the impact node construction. The new control method application instead of the known one provides current amplitude decrease. It also gives less effect of the impulse electromagnetic machine on the power-line because of three voltage half-waves applied to the inductors over the operating cycle.
