Abstract: After harvest grain mixture separation is a very essential operation. The most common way of grain mixture processing is based on swing vibrating screeners. In terms of mechanics and energy their bottleneck is a reduction electric drive based on induction rotation engines. As the result the electric drive has low efficiency, higher weight, limited ways to regulate oscillation motion of screens. The aim of the investigation is to develop a gearless electric drive for swing vibrating screeners with regulated oscillation properties. The study deals with a mechatronic system based on a linear induction engine. It enables to simplify an electric drive as well as to adjust necessary settings for complex oscillating movement of screens. Screen vibrations are controlled by changing turn-on period and frequency of the linear induction engine. Amplitude of regulated vibrations can be more than 0.01 m with frequency <3 Hz.
