AB - Surface biomimetic microgrooves were widely unitized in various fields from physics and chemicals to engineering, because of the periodic, directionally arranged, controllable in-size structures. Frictional regulation through surface microgrooves especially attracted the attention of devices, including piezoelectric motors, that use friction transformation. The motor is activated by the inverse piezoelectric effect of the piezoelectric ceramic attached to the stator, which causes a slight ultrasonic vibration at the tip of the stator. Improving and stabilizing friction is essential in designing and applying piezoelectric motors. After the stress transfer analysis of the textured microgrooves on the slider, the experimental results approved the positive regulation effect of the textured discontinuously vertical microgrooves. It achieves a maximum operating speed of 0.17 m/s and a power output of 0.28 W at 75 Vp. The mechanical performance is improved compared with other shape textures. This study demonstrates the contribution of surface microgrooves to friction regulation under dry friction and ultrasonic vibration, providing a reference for the friction enhancement design of the mechanical characteristics and service behavior of piezoelectric motors.
