At present worked out is new measuring system for evaluation of dynamic properties of stepping motors. In projected stand founded executing of following measurements dynamic characteristics - pull-in torque and pull-out torque. These characteristic have to be determinate both during work in mode full step, how and half and micro steps. Range of Chapter 1 and 2 embraces: - proposition of methods and general algorithms of marking of pull-in and pull-out characteristics (Fig. 1), - presentation of subassemblies (Tab. 1) and parameters of set of torque transducers, used in the station (Tab. 2). There is a possibility of use a set of specially designed in IMiF WUT torque meters: dynamometric type wit piezoelectric transducers, OPMZ type optoelectronic rotary torque meters [4] and special micro-range optoelectronic stationary meter. To load applying practical are electromagnetic powder brakes (IEI Międzylesie or VIBROMETER) with specialized control units. Computer-based data acquisition system with PC-based card enable the registration of the torque signal during the number of examinations. The view and possible structure of equipment is presented on Fig. 2, and exemplary results of determination of both characteristic of small PM stepping motor - on Fig. 3. The influence of additional mass M.I. is presented on Fig.4 and pull-in characteristics in 1/2 and 1/32 microstep mode are presented on Fig. 5. During preliminary testing PM type stepper motor we notice possibility of causing uncontrolled oscillations or even resonance of all parts used in testing station, this effect is bring about by bellow coupling used in test equipment and slightly incorrect ratio of motor and equipment mass M.I. Authors plan to use presented equipment for an analysis of the influence of research methods on the measuring results. The goal of that work is proposition of "Quality factor" of pull-in and pull-out characteristics.
