Winding, Compound

A method of winding a generator or motor in which a shunt winding is used for the field magnets and in which also a second winding of the magnet is placed in series with the outer circuit. (See Winding, Series--Winding, Shunt.) IMG:8956969607833025625_578F350.JPG: Fig. 350. CHARACTERISTIC CURVES OF SHUNT AND SERIES WINDING. The object of compound winding is to make a self-regulating dynamo and this object is partly attained for a constant speed. The characteristic curves of shunt and series winding are of opposite natures. The first increases in electro-motive force for resistance in the outer circuit, the latter decreases under the same conditions. If the windings are so proportioned that these conditions for each one of the two windings are equal and opposite, it is evident that the characteristic may be a straight line. This, however, it will only be at a single speed of rotation. 579   STANDARD ELECTRICAL DICTIONARY.
