Theoretical and Experimental Study of an Asynchronized Synchronous Machine

The paper considers the control and the behavior of an asychronized synchronous machine. The d- and q-axis field excitation voltages are controlled to provide characteristics that combine the advantages of both syLchronous and induction machines. The properties are described with the aid of the phasor diagram, and expressions are presented for the synchronous and asynchronous components of the armature voltage, the active and reactive powers, and the torque. Experimental results for a 2 kVA machine are compared with calculated results for both steady-state and transient operation, and the action of the novel excitation system is described.
