CHAPTER XXLMOTOR WITH A CONDENSER INTHE ARMATURE CIRCUIT.WE NOW come to a new class of motors in which resort is hadto condensers for the purpose of developing the required differenceof phase and neutralizing the effects of self-induction. Mr.Tesla early began to apply the condenser to alternating apparatus,in just howr many ways can only be learned from a perusalof other portions of this volume, especially those dealing withhis high frequency work.Certain laws govern the action or effects produced by a condenserwhen connected to an electric circuit through which analternating or in general an undulating current is made to pass.Some of the most important of such effects are as follows :First,if the terminals or plates of a condenser be connected with twoof which are made to rise andpoints of a circuit, the potentialsfall in rapid succession, the condenser allows the passage, or morestrictly speaking, the transference of a current, although itsplates or armatures may be so carefully insulated as to preventalmost completely the passage of a current of unvarying strengthor direction and of moderate electromotive force. Second, if acircuit, the terminals of which are connected with the plates ofthe condenser, possess a certain self-induction, the condenser willovercome or counteract to a greater or less degree, dependentupon well-understood conditions, the effects of such self-induction.Third, if two points of a closed or complete circuitthrough wT hich a rapidly rising and falling current flows beshunted or bridged by a condenser, a variation in the strength ofthe currents in the branches and also a difference of phase of thecurrents therein is produced. These effects Mr. Tesla has utilizedand applied in a variety of ways in the construction and operationof his motors, such as by producing a difference in phase in thetwo energizing circuits of an alternating current motor by connectingthe two circuits in derivation and connecting up a condenserin series in one of the circuits.
