s the G.E.A.-605 motor, built by the General ElectricCompany• The magnet field consists of a cylindrical iron ring,built up of thin annular iron laninations, insulated from oneanother by japan, and securely bolted together. The interiorportions of the punchings are so shaped that they form four poles,which are slotted for the reception of the compensating fieldwindings. The exciting windings are distributed over the wholesurface of the field. The field laminations are held in an outersteel frame which forms the frame and casing of the motor. The armature bearings are carried in the frame heads, madeof one piece of malleable iron. The linings are made of unsplitbronze sieves, finished all over with a thin layer of babbittmetal soldered to the interior. The babbitt is of such a thick-ness that it does not allow the armature to rub on the polesshould it melt out by heating. The construction of the armature and the commutatorallow the bearings to extend into them and thus increase their
