, as indicated in Fig. 226, or eight in a slot, as in Fig. 227, T-shaped teeth can^ be em-ployed. It must be rememberedthat, owing to the magnetic shield-ing of the teeth, the conductors are subjected practically to centrif-ugal force only. Unless the pole-faces are laminated, the top breadthof the… … Fig. 225. Partially Completed Ring-Wound Armature 192 DESIGN 183 must be kept very narrow, otherwise the high flux-density requiredin the teeth for sparkless collection of current will not be attained. All electric and magnetic consider-ations point to having the slots andteeth narrow and numerous;…
