PHASOR DIAGRAM OF THE
INDUCTION MOTOR
The steady-state characteristics of an induction motor are
described by means of phasors which are computed
using the standard equivalent circuit and are then plotted in the complex plane
in a speed range from standstill to synchronous. The input voltage (black) is
chosen as reference; the stator and rotor currents and the stator and rotor
fluxes are shown. The trajectories of these phasors
approximating portions of circles are indicated in blue. The corresponding
torque-speed curve is also plotted.
