The real time control of the rotation rate of a microscopic particle trapped in a focused laser beam by change of the ellipticity of polarization of laser radiation has been studied. The change of the ellipticity of polarization was carried out with the help of the modulator using orientational S-effect in nematic liquid crystals. The dependence of the particle rotation speed on the state of polarization ellipticity was determined. The calculation of an angular momentum of rotation per a unit of energy of the light field is shown.
