Abstract:Aiming at the problems of low precision, single function and low degree of automation in the existing testing system of characteristics of linear ultrasonic motor, a test system of characteristics is designed for measuring mechanical and transient characteristics of linear ultrasonic motor, which is mainly composed of motor drive module, data acquisition module, test control and data processing module. The motor drive module mainly takes the STM32F429 micro-controller as a core controller, which can conveniently realize multi-parameter adjustment of its drive signal. The data acquisition module is mainly composed of a displacement sensor, a tension-compression sensor and a high speed data acquisition card. The test control and data processing module are mainly realized by a computer. The mechanical and transient characteristics of the "butterfly" type linear ultrasonic motor are tested by using the system. The results show that the system can well achieve the measurement of characteristics of linear ultrasonic motor, and can be conveniently operated and easily expanded. © 2018, Editorial Department of JVMD.
