In this paper, the experimental and the numerical results on the rotational speed fluctuations of pump-controlled axial piston motors in the low speed range are presented. It is found that with the decrease of the mean rotational speed, the number of peaks in the output torque and, therefore, in the rotational speed per rotation varies from z (the number of pistons) to 2z, 3z, etc. Because of such nature of the torque, resonance phenomena occur at and in the vicinities of particular mean rotational speeds Numerical results show that the principal causes of the rotational speed fluctuations of axial piston motors are the pulsation of the displacement volume and the variation of the friction torque with the angle of rotation. good agreement is obtained between the experimental and the numerical results.
