The commutator segments of the armaturesare deep and wide, giving high conductivity and perfect radiationof heat at overloads as well as insuring long life and freedom fromsparking. In order to decrease the cost of repairs, the armatures of thesemotors have been built on quills so as to facilitate removal. Theoil ring bearings have been standardized in a form similar to thoseso successfully employed in street railway service. The shafts havebeen made of a specially high grade of steel, and the journals arelarge, insuring minimum attention, and are protected from dirt andgrit by a perfected form of dust-proof packing. As many parts as possible of these new motors have been stand-ardized and are, therefore, interchangeable. Any size of motor maybe fitted with or without axle arms, according to the desire of thecustomer as to the method of suspension. The charging panel shown in the General Electric Companysexhi
