SQUIRREL-CAGE INDUCTION MOTOR

Synchronous view

In the synchronous reference frame, all variables appear as dc quantities in steady state. All space vectors are  frozen in space in the shown fixed position based on the assumption that the original stationary and the synchronously rotating reference frames coincide at time t = 0.  These vectors may then be directly associated with the (per-phase) phasors of the induction motor, combined in a phasor diagram, and interpreted by means of an equivalent cicuit made up of a magnetizing inductance in parallel with the rotor leakage inductance acting in series with a resistor.
