Abstract

The article considers a computer model of a reciprocating-rotational electric drive based on rotational and linear motion electric motors implemented in the Matlab (Simulink). Giving the working body of a centrifugal separator with a vertical axis of rotation of axial vibrations loosens the grain mixture and cleans the main grain crop from weed impurities. In addition, the superimposition of vertical inertia forces to the centrifugal inertia force makes it possible to ensure the maximum possible value of the coefficient of the living section of the sieve. In addition, the superimposition of vertical inertia forces to the centrifugal inertia force makes it possible to ensure the maximum possible value of the coefficient of the living section of the sieve. The use of a linear inductor motor (LIM) paired with an elastic element for the implementation of axial oscillatory movements of the working body makes it possible to simplify the design of the drive mechanism of the separator. According to the results of the conducted studies of the simulation model of a reciprocating-rotational electric drive, it was determined that with a decrease in the length of the hole l relative to the circumference of the ring (secondary element of the LIM), the magnitude of the displacement of the center of the oscillation of the working organ from the point of the beginning of its movement increases and the amplitude of the oscillation increases.
