The demands for electric motor applications in case of shipboard installation are summarized as high efficiency with good power quality indices as well as small volume and weight, high reliability and rotating redundancy and of course low cost. The present paper deals with a variable speed drive based on a conventional rotor wound induction motor, which has similar characteristics to a DC series machine. More specifically, the motor system considered is a naturally commutated series excited rotor machine where the excitation current is obtained naturally by placing the excitation winding in the dc link. The motor used is a standard type wound rotor induction motor operating as a synchronous machine. The motor scheme described is the fourth version in the evolution of the series naturally commutated variable speed drives. Thus, a summary is given on past editions stressing the advantages and disadvantages of the various schemes as well as the introduction of the last proposed scheme.
