Abstract
6550. Akt.-Ges. Brown, Boveri, et Cie. March 17, 1911, [Convention date]. Exciting; rotary transformers and motorgenerators.-The motor of a motor-generator for high - tension direct current is started as a series motor and run with a shunt or compound characteristic by wholly or partly annulling the action of the series winding f by short-circuiting it, or by means of a counter-compound winding g, the motor then being excited by a winding h in shunt with the dynamo d. The winding g is connected in series with the armature d. An additional field winding may be provided on the dynamo in series with the motor armature a. In a modification, the set consists of a single machine having two commutators. In the application to a Ward-Leonard system l, m, as shown in Fig. 4, a resistance switch is provided for short-circuiting the series field windings f, j on the motor and dynamo after starting. The motor a may give up mechanical energy to machine tools &c., and the dynamo d be used simply as an exciter,
