Draw the complete circular stator winding for a three
phase delta connected AC generator consisting of 4 poles
and 24 slots using a parallel connection. Your submission
must consist of two drawings as follows:
One drawing must show the winding arrangement of the
phasegroups in the slots of the stator highlighting the
start and finish of each phasegroup
The other drawing must show only the end connections of
each phase group for a parallel connection of the
phasegroups and a delta connection of the phases
The use of AutoCad or any other software is encouraged.
For the oscillator resonance circuit shown in Fig. (5), derive the oscillation frequency,
Feedback and open-loop gains.
