CHAPTER VII. 



Calculation of a Single-Phase Current Motor. 



THE three-phase current motor, the design of which was given 

 in chapter V, is reproduced in Fig. 32. We shall now proceed 

 to examine the behavior of this motor if running as a single- 

 phase motor. For simplicity's sake we shall retain the winding, and

investigate what voltage is most suitable for it. The motor, as will 

 be remembered, has 16 poles, and is to work again at 60 p. p. s. 



III. Field Winding. 128 slots, 10 conductors in each slot ; diameter 

 of wire, 0.229" ; resistance hot, 0.28 ohm.
