The design and characteristic research of a dual-mode inertia motor

Abstract

The design of a dual-mode inertia motor involves an actuator that can generate translational and rotational motion without connecting the actuators serially. Traditionally, translational or rotational actuators should be stacked serially to have multi-axis degrees-of-freedom. The experimental results of this study display performance characteristics such as linearity, resolution, velocity and the most excellent operating frequency.

Piezoelectric Inertia Motors—A Critical Review of History, Concepts, Design, Applications, and Perspectives

“…It has been measured using different methods: making the slider move against a spring, the force is either determined from the deformation of the spring [61,74,75], or using a load cell connected to the spring [76,77]. Other authors make the slider move directly against a load cell [67,[78][79][80][81], or the force is exerted to a part connected to a load cell instead of a slider [82].…”

“…Recently, it has been shown that running the slider against a spring is a robust method of determining the force generation potential of an inertia motor, providing results independent of the spring stiffness as long it is sufficiently low ( [87] (pp. [73][74][75][76][77], in short form also [77] (p. 7)). This method is also suited for non-iterative numerical simulation [87] (pp.…”

“…This method is also suited for non-iterative numerical simulation [87] (pp. [73][74][75][76][77]. It thus appears as an advantageous measurement method for comparing the force generation performance of different inertia motors.…”

Verification of the feed-forward control for a piezoelectric actuator using differential flatness approach

“…A piezoelectric inertia motor is a type of electric motor that transforms electrical energy into motion using the inverse piezoelectric effect (Uchino, 1997). Piezoelectric inertia motor has a simple construction and can be simply controlled using single driving signal (Cheng and Hung, 2011; Hunstig and Hemsel, 2010). Piezoelectric inertia motor consists of three main components: sliding rod, piezoelectric actuator, and slider.…”
