Within the framework of a Boltzmann-Lorentz equation, we analyze dynamics granular rotor immersed in bath thermalized particles presence frictional torque on axis. In numerical simulations observe two scaling regimes at low and high temperatures. large friction limit, obtain exact solution model corresponding to asymptotic behavior equation. limit mass small friction, derive Fokker-Planck equation for which is also obtained.
