We have calculated components of the torque and the interaction energy of rotating dipole particle in the case where the rotation axis is perpendicular to the surface and the dipole axis is inclined to it. An important property of this system is its quasistationarity. When the dipole axis coincides with the rotation axis, the particle does not experience braking and may revolve for infinitely long time. When the dipole axis is inclined to the surface, a situation is possible where the particle is repelled off the surface provided that the rotation frequency is tuned to the absorption resonance of the surface. The established effects are important in trapping and manipulating rotating nanoparticles close to the surface.
