ЧТО ОЗНАЧАЕТ СЛОВО PHASOR
Phasor
В физике и технике фазовый вектор или фазор представляет собой представление синусоидальной функции, амплитуда, частота и фаза которых являются временными. Это подмножество более общего понятия, называемого аналитическим представлением. Фазоры разделяют зависимости от A, ω и θ на три независимых фактора. Это может быть особенно полезно, поскольку частотный коэффициент часто является общим для всех компонентов линейной комбинации синусоид. В таких ситуациях фазоры позволяют эту факультативную характеристику исключать, оставляя только функции A и θ. В результате тригонометрия сводится к алгебре, а линейные дифференциальные уравнения становятся алгебраическими. Поэтому термин phasor часто ссылается только на эти два фактора. В старых текстах фазор также упоминается как синор.

7 - Multiplying a phasor by/ or e,90° or 1Z90° amounts to rotating it by 90° in the
counter-clockwise direction in the phasor diagram. This amounts to converting a

The phasor method is very advantageous because the EM equations in the
frequency domain are algebraic equations, which are easier to solve than the
corresponding equations in the time domain, which are partial differential
equations.
