“…Based on the power loss theoretical model of ultrasonic motor, Xiaolong Lu et al established a research method to evaluate the network loss of power. The results show that the friction loss accounts for the largest part of the medium loss, and analyzed the temperature distribution of the motor, which is highly consistent with the experimental results [13][14][15][16][17]. These studies show that the piezoelectric part also has a great impact on the loss of hybrid drive motors.…”

Temperature rise has always been one of the main researchfocusesof the motor. When the temperature is too high, it will have a serious impact on the stability and reliability of motor performance. Due to the special structure of electromagnetic piezoelectric hybrid drive motor (EPHDM), the loss and temperature distribution of electromagnetic drive part and piezoelectric drive part werestudied. By analyzing the operation principle of the motor, the loss of each part wasresearched. On this basis, the loss of the electromagnetic driving part and piezoelectric driving part werecomputed by using the coupling iterative calculation method. The temperature contour map of the motor wasanalyzed by simulation, and the temperature characteristics of each part of the motor werestudied. Finally, the experimental verification of the prototype, the reliability of the theoretical model, and simulation results wereproved. The results showed that the temperature distribution of the motor is reasonable, the winding temperature is relatively high, and the core temperature and piezoelectric stator temperature are relatively low. The analytical and experimental methods are provided for the further study of heat source optimization.

“…Furthermore, as two orthogonal vibrations with the same resonance frequency and a temporal phase shift of 90°can also form elliptical movement, combination of vibrations, such as longitudinal and bending vibrations [11][12][13][14], longitudinal and torsional vibrations [15][16][17], two orthogonal longitudinal vibrations [18][19][20][21][22][23][24], and two orthogonal bending vibrations [25][26][27][28][29], can be utilized for constructing piezoelectric motors. Recently, a new principle for linear driving was proposed by Lu et al, in which driving principle using ultrasonic vibration induced friction reduction was proposed and investigated; and the two exciting frequencies of the driving and friction reduction voltages need not to be the same [30].…”

“…One of the areas is actuation. Because of their advantages of simple structure, flexible design, high resolution, and low power consumption, many piezoelectric actuators have been developed [11][12][13][14]. Actuators can be classified by vibration state into the resonant type and the non-resonant type.…”

A piezoelectric actuator using a lever mechanism is designed, fabricated, and tested with the aim of accomplishing long-travel precision linear driving based on the stick-slip principle. The proposed actuator mainly consists of a stator, an adjustment mechanism, a preload mechanism, a base, and a linear guide. The stator design, comprising a piezoelectric stack and a lever mechanism with a long hinge used to increase the displacement of the driving foot, is described. A simplified model of the stator is created. Its design parameters are determined by an analytical model and confirmed using the finite element method. In a series of experiments, a laser displacement sensor is employed to measure the displacement responses of the actuator under the application of different driving signals. The experiment results demonstrate that the velocity of the actuator rises from 0.05 mm/s to 1.8 mm/s with the frequency increasing from 30 Hz to 150 Hz and the voltage increasing from 30 V to 150 V. It is shown that the minimum step distance of the actuator is 0.875 μm. The proposed actuator features large stroke, a simple structure, fast response, and high resolution.
