Abstract: Using the Hunt&Reffert catalogue, based on Gaia DR3, the behaviour of the velocity components and the standard deviations of the velocity components of open star clusters were analyzed in the interval of Galactocentric distances from 5 to 12 kpc. Positions of the Lindblad resonances and the corotation radius are determined from the constructed rotation curve of the Galaxy. The obtained values are close to the positions of the Carina-Sagittarius and Perseus arms. The velocity components do not show any dependence on the position of the spiral arms. The standard deviations of the velocity components demonstrate an increase in the region of the internal Lindblad resonance with relatively small errors.
