    Based on the tightly focusing approach, the perfect optical vortex beams are generated at the geometric focal plane. The optical forces and torques exerted on the micro-sized particle in the perfect optical vortex beams are calculated. Numerical results show that the micro-sized particle is trapped on the ring of perfect optical vortex beams and is driven to rotate around the optical axis. The orbital torque will firstly increases and then tends to be stable with the increase of the topological charge value. In addition, the influence of circular polarization state, radial polarization state and azimuthal polarization state on the force and orbital torque of micro-sized particles are investigated in perfect optical vortex beams. The results show that the state of polarization of perfect optical vortex beams will affect the optically induced orbital motion to some extent. The circular polarization state of perfect optical vortex beams is superior to drive the orbital motion of the particle.
