Fig. 21 shows a truck of one ofthese locomotives with the cabs removed so as to show themethod of mounting the motors. The connecting rods andall reciprocating parts are counterbalanced so as to elimin-ate pounding on the track. In the New Haven locomotivesthe motors are mounted upon a quill surrounding the driv-ing axle, the torque being transmitted to the wheels directlyby projecting pins on the armature structure engaging insockets in the spokes of the driving wheels.

Fig. 22 gives,at the top, two views of a quill, and at the bottom, twoviews of the quill in place upon the axle before the motor ismounted. In some installations, notably in the New YorkCentral locomotives, the motor armatures are mounted di-rectly on the driving axle, being rigidly connected Motor Curves. — The characteristic curves of amotor include curves of speed, torque, and efficiency interms of the current flowing through the mo
