Abstract
Aiming to study the friction and wear performance of slipper pair in high-pressure axial piston pump with 35 MPa and above, it is necessary to use a slipper pair friction and wear tester with very stable test accuracy. However, the main output source of accuracy assurance in testing machine is the accuracy of spindle motor. Aiming at this problem, two methods, space vector pulse width modulation (SVPWM) vector control and variable frequency speed control, are proposed to control the rotating speed of the spindle motor of MCMS-10 (machine type) slipper–wobble friction and wear tester. The results show that the final spindle velocity fluctuation obtained by SVPWM analysis and simulation for MCMS-10 tester is more stable than the frequency conversion method. The motor can also quickly recover to the given reference value when the torque mutates. At the same time, the reflecting speed is very sensitive when the speed of the spindle is changed, and the dynamic response speed tracks the speed given by the spindle when the speed of the spindle is mutated, which meets the test requirement of the friction and wear tester to the slipper pair.
