. A text-book of electrical engineering;. otor 357 stator, is built up of sheet-iron stampings, and is wound in exactly the samemanner as the armature of the generator. The ends of the stator-windingsare connected to the corresponding ends of the generator-windings (). If the armature of the generator rotates, the connections must, ofcourse, be made by means of slip-rings. If the armature be rotated in the direction indicated, clockwise,then an towards the observer will be induced in the wires under thesouth pole, and away from the observer in those wires which are under thenorth pole. This is shown by the arrows in the figure. If we neglect anyphase displacement due to self-induction, the arrows will represent currentat its maximum value. At the moment chosen in the figure there will beno current in the other phase-winding. By tracing out the currents in thestator, we find that the field produced will be as indicated by the dottedlines. The lines of force leave the stator at N, pass across the internal air.
