Transient Analysis of the Metadyne Generator [includes discussion]

The phenomenon of self-excitation, often met in commutator machines, will be investigated for the metadyne case. Methods of stabilization that are incorporated as built-in features also will be discussed. For the purpose of checking the analysis, an experimental verification is carried out for several metadyne configurations. Actual steady-state and transient characteristics are given and compared with calculated analytical results. The extent of the validity of the assumptions basic to the analysis is evaluated in the light of these experimental results. The analysis will disclose characteristics of the metadyne which differ greatly from the conventional types of d-c machines, and which therefore can be useful for many applications. Attention will be focused on the inherent high response rate of many metadyne configurations.
