About the Book

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1911 Excerpt: ...the value of OR' and the current 0l =-7= will in VR2+X2 crease to 0I"', and therefore the input OEXl"" will increase just sufficiently to take care of the added load. If the load be suddenly decreased, the motor will temporarily speed up, oe will take the position of oe," OR will be reduced to OR" OR," and the current 0I =, ----_ will decrease to 0IV' and there'Vr2+x2 fore the input = OEXIv will decrease just sufficiently to balance the reduced load. From this discussion we can see that a synchronous motor will operate satisfactorily and adapt itself to varying loads by a slight phase swinging of oe with respect to OE. If the load is increased too much, the motor will fall out of synchronism and stop, and the heavy current produced will throw out the circuit breakers. (For a discussion of stability of synchronous motors, see Sheldon, Mason, and Hausmann, "Alternating Current Machines," eighth edition, 1909, pp. 249-256; also Franklin and Esty, "Alternating Currents," second edition, pp. 141-150.) 88. Hunting.--Referring to Fig. 164, it will be noticed that when the load is increased the b.e.m.f. of the motor oe falls back to the position oe'. As oe falls back toward oe', the input increases, but does not take care of the increased output until it reaches oe'; but when passing oe', the motor is slowing up; at this point, oe', the input is only able to take care of the output; therefore the motor continues to slow up, but now the input has increased more than enough to take care of the output, so that the motor speeds up. In other words, when the b.e.m.f. vector oe has to take up a new position with respect to the impressed e.m.f. OE, it does not immediately change from the old position (oe) to the new position...
