**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.**
