Acoustics
Fundamental Attributes $$ c = \lambda f $$ $$ f = \frac{1}{T} $$ $$ \omega = 2 \pi f $$ $$ k = \frac{2 \pi}{ \lambda} $$ Where \( c \) is the speed of sound in the medium, \( \lambda \) is
Induction Machines
An induction motor consists of an external stator and an internal rotor. Windings embedded in the stator is excited by a 3-phase AC supply to produce a rotating magnetic field.
SPQ and Power Factor in AC Systems
SPQ Apparent power, \( S \), as a product of measured RMS voltage and current, can be split into the real and complex power conterparts. Where \( \phi \) is the phase angle, \( S
Phasors and Impedance
Phasor Representation Parameters in AC systems have three variable factors as described in the general form: $$ v(t) = \hat V \sin (\omega t) $$ Since the frequency in a system is
AC Systems
Properties of a Sinusoid General Form $$ v(t) = \hat{V} \sin ( \omega t + \phi ) $$ Where \( \hat{V} \) is the amplitude, \( \omega \) is the angular frequency, \( \phi \) is the phase. Period
