Tile cnnductors are soldered directly into ears forming a part. FIG. 7.—G. E. 66 MOTOR, FRONT VIEW WITH COVERS REMOVED of the commutator segments, avoiding the use nl c<jnnecting the back end of the armature the top and bottom bars areconnected together with tinned-copper clips ri\ eted and soldered,but easily removed in case it is desired to replace the top barswithout disturbing the bottom bars. The conductors are heldin the slots by tinned-steel wire bands imbedded in the core be-neath the periphery, the wires being soldered together and heldby tin clips. The commutator has 19S segments of copper insulated entirelywith mica, and clamped in a cast-steel shell. The diameter of thecommutator is is. There are four field coils, one for each pole, wound on metalspools, held in place by the laminated pole pieces. The wind-ings are thoroughly insulated from the spools with mica, asbestosand cloth, and between turns with asbestos. This constructionmakes a practically fireproof spool impervious to moisture.
