. Electric railway journal . Interpole Motor, Showing Field and Armature Among its advantageous features are light weight, splitframe, superior spider construction, bolted commutator,strap-wound armature coils and double-stud brush holders. The frame is of cast steel and is divided , bearing housings and field coils may be removedwithout jacking up the car and removing the Small-Size Interpole Motor A large opening is provided above the commutator forready access to the brush holder. A cover is furnishedwhich is securely fastened to the frame with a T-bolt anda dam-locking device. The armature and axle bearings each have two separateoil compartments connected at the bottom. The large reser-voir is filled with long fiber-wool waste, through which all large surfaces. While being made, the coils and leads areformed into the exact contours they should assume in thearmature slots, so that no bending or excessive forcing isnecessary to insert or connect them. The spider armature construction makes it possible toremove the shaft whenever necessary without injuring thewindings. The spider also reinforces theshaft so that the probability of bent shaftsis reduced to a minimum. The commutatorsare bolted, a construction to prevent the barsfrom becoming loose. The mica extends be-yond the bars in the rear of the commutator to eliminate thepossibility ofshort circuit
