Technical Electrodynamics| Summary: | The specified expressions for definition of electrical power factor of electromechanical systems in view of asymmetry of parameters, not sinusoidal processes, and dynamic modes of operation are justified and investigated. Expressions are intended for comparative research of systems, forming of criteria of optimum projection at an assumption of a symmetric and sinusoidal supply voltage. An input information for accounts are time dependences of currents of a web and delta voltage. Specification, in comparison with accounts on the first harmonics and instantaneous powers, is augmented with increase in a degree of an aberration from sinusoidal processes, on an example of thyristor regulation of voltage of an induction motor it reaches 20 %.
