Mathematical simulation of oscillating electric drives in current-frequency modulation

One of the perspective directions of the development of reductor-free oscillating electric drives (OED) is their construction on the basis of the electrical machines working directly in a mode of constrained oscillations. Such electric drives provide practically all required range of the reproduced oscillations in the amplitude, frequency and mode. OED mathematical models have been developed on the basis of a double supply machine and an asynchronous motor in a solid coordinate system in relation to axes of stator windings. In creating these models, the ideal current sources acted as power sources and the machine as a source of oscillatory force (a source of mechanical moment).
