Abstract: For the first time, we have calculated the attraction force, frictional torque, and heating rate that are caused by fluctuation-electromagnetic interaction of a small spherical particle uniformly rotating at a constant angular velocity near a heated surface. Closed analytical formulas are obtained for these quantities. It is shown that the stopping time of a particle rotating in the near field of the surface is much less than the stopping time under rotation in vacuum space.
