Short circuit current


 

Circle diagram


 

Both of the layers of the voltage phasor diagram have to be circled twice in order to number all the phasors.

 

Operating characteristics

 

Now, the equivalent circuit of an asynchronous motor per phase, the quantities of which are calculated in the machine design, is worth recollecting. Figure 7.12 illustrates a single-phase equivalent circuit of an ordinary induction motor per phase, a simplified equivalent circuit anda phasor diagram.
