Oscillating motion motors general theory problems

Research into the work of electric machines with cyclic motion composing oscillating electric drives of various purposes as well as the definition of further efficiency increase of their use is one of the most important problem nowadays. The solving of this problem is the new step in industry process improvement. In spite of these motors´ qualities, most of them do not allow to regulate operatively output oscillation parameters, such as frequency, amplitude, phase and form during the operation. Reductorless oscillating electric drives (OED) installed for lest time are the most perspective ones. They are build on the base of all kinds of serial electric drives of angle and linear motion: asynchronous; direct current motors; and asynchronous and step motors operating in the mode of cyclic motion. Reductorless OED on the base of asynchronous electric drives allow, in particular, to provide practically the whole needed range of oscillations parameters created and regulated by these drives
