W artykule przedstawiono modułowy system do wyznaczania charakterystyk częstotliwościowych silników skokowych. Pomiar momentu może być prowadzony bezpośrednio "na wałku" silnika (momentomierzem obrotowym serii OPM lub poprzez pomiar reakcji stojana (momentomierzem dynamometrycznym z piezoelektrycznym czujnikiem siły. Oprócz badań konkretnych silników i sterowników stanowisko umożliwiło weryfikację metod badawczych i doskonalenie opisu formalnego mikromaszyn i procedur sterowania.
The paper presents a modular test system designed in the Division of Fine Mechanics Design - the Institute of Micromechanics and Photonics, intended for setting frequency depended characteristic curves of a stepper motors. There is a possibility of measurement of two kinds of characteristics (pull-in and pull-out), both according to two different methods (see Fig. 1). During determination of characteristics the torque metering can be taken directly from a motor shaft with use of optoelectronic OPM series rotary torque meters or it can be processed also as a stator reaction force measurement made with use of a dynamometric torque meter equipped with a piezoelectric force transducer. Figs. 2-5 present possible configurations of a test bed and a set of transducers. The photo of the selected configuration is shown in Fig. 6 and view of the electronic module in Fig.7. Control and measurements can be made by a data acquisition card installed in a personal computer. The tested motor can be driven in full-, half- and micro-step modes, depending on its own driver. The main window of a control program (see Fig .8) allows a user to select the desired test method and its parameters. Algorithms of the test bed working modes are shown in a synthetic way in Figs. 9 and 10 (for pull-in curve). The experiments results, despite its utilitarian use (tests of particular motors), can be applied to scientific research - comparison of different methods for determination of characteristics. The exemplary results are presented in Figs. 11-13. - Źródło:
