An experimental mechanism for cleaning grain mixtures with a drive from a linear asynchronous electric motor has been developed and manufactured in the Bashkir State Agrarian University. More favorable conditions for sifting the grain mixture are created as a result of the use of an asynchronous linear electric motor for its drives in comparison with traditionally used machines driven by rotation motors. Based on the Lagrange equations, a mathematical description of the movement of the links of the mechanism is carried out and the electromagnetic force required in accordance with the cleaning technology is found. It is created in the windings of a linear electric motor by an electronic switch. It is found that the shape of the pulse of the required electromagnetic force is close to sinusoidal. However, it is possible to replace the electromotive force varying according to the sinusoidal law by a force constant in modulus and equal in impulse.
Keywords: grain cleaning machine, linear electric motor, electromotive force, electronic switch.
