THE INDUCTION MOTOR. 



might be put down; but this should be no rigid rule. Never take 

 fewer than 3 slots per pole and phase, if possible. If you put too few 

 conductors in a slot, the leakage field is not saturated, and thus the

advantage of a great number of slots may be balanced by this greater 

 leakage. 



Thus we see that in spite of many rules, still a great deal is left to 

 the individual judgment of the designer. 



35. To enable the reader to form for himself an opinion of the ac- 

 curacy of the theory, I give the complete experimental data of a small 

 three-phase current motor with short-circuited armature.
