The motors aredirect-current series motors, as per ordinary practice. Theyhave four poles, and the non-laminated pole pieces are placedhorizontally and vertically, the latter having no windings, thehorizontal pole pieces having each two field coils. The outsideappearance of the motors is similar to American construction,the electrical parts being protected by two shells, completely. FIG. 13.—FLEXIBLE COUPLING USED BETWEEN MOTOR SLEEVEAND AXLE enclosing them, the joint being horizontal and secured by lower shell of the motor carries the armature bearing andthe lower part of the axle bearings. The commutator has 113segments. The motors were supplied by the Alioth Company. Both motors of the same motor car are permanently in multi-ple, and this has been done for avoiding the possibility experi- enced with series coupling of motors of slipping. Five positionsare employed on the controllers, which are operated, as beforestated, by pneumatic means. Three positions use rheostaticcontrol of the armature only, and in the last step the fieldcoils are shunted. This plan was adopted by the Paris-Lyons-Mediterranean Railroad Company so as not to be limited to
