.cos0, 109- Synchronous Motor 351 where cf) is the angle between the terniinal pressure and the current. Fromthe figure we see that FH = V cos ^, so that Pi = I.FH wsitts. A certain amount of this power will be lost in heating the armaturewinding, viz. j,j^^ ^ j^j^^ ^ J p^ ^^^^^ The mechanical… … \ Generator ^K Fig- 355 Fig. 356 If <j)i be the angle between the vector of e.m.f. and the current vectorproduced backwards, we have CH = E. cos (j)i. This gives the following equation for the mechanical output of the ^°t°^= P = E.I.cos cf,j_ (162). We might also have expected this result from…
