Magnetic Properties and Applications

A general method is given to establish equivalent circuits for the determination of the hunting characteristics- such as damping and synchronizing torques-of standard types of electrical machines. The method is illustrated by setting up steady-state and hunting equivalent circuits for the salient-pole synchronous machine having amortisseur windings and for the doubly fed single-phase Selsyn with unbalanced windings, special cases of which are the capacitor motor and doubly fed polyphase motor. A companion paper, ``The Doubly Fed Machine,'' contains a detailed study of the characteristics of one of the equivalent circuits as measured on the a-c network analyzer.
