## 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 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

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

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

Separately Excited \( I_A \neq I_F \) Separate supplies for field and armature $$ T = K_T \cdot I_F \cdot I_A $$ $$ I_F = \frac{V_F}{R_F} $$ $$ E_
