Abstract

The great importance during design and production of devices with linear machines is given to develop of the corresponding mathematical models. Any model has its restrictions. The model functions within the accepted assumptions which are corresponding to the modeling purpose. For the simplification of the calculation equations, the nonlinear properties of ferromagnetic materials of magnetic conductors often are neglected, as well as not inertance of parameters of the machine in time, their dependence from current, frequency or temperature, influence of Eddy currents, etc. The most reliable way for validation of the developed model is carrying out experimental studies of a real prototype of the device. During such researches it is possible to estimate influence of mechanical, electromagnetic or thermal processes which are not considered in mathematical model. Reliability of the received results considerably depends on quality of the equipment, a choice of experimental techniques, and the accuracy of measuring devices. For the testing of linear oscillatory machines, simultaneous registration of mechanical and electrical characteristics, as functions of time is essential. Unlike traditional rotary electrical machines for which the different test and load equipment is developed, for linear oscillatory machines such experience is absent so far. Therefore the problem of creation of experimental setups for obtaining operation properties and determination of parameters of linear machines is important today. The purpose of this work is development of the experimental setup for researches of linear oscillatory machines in different operating modes and carrying out experimental studies of characteristics of the test specimen of magnetoelectric linear motor in according with the provided techniques.
