Three-Phase Synchronous Generator

摘要

The object of the invention is a three-phase synchronous generator on the type of machine with switchover of the magnetic flux and containing three stator packets arranged in a row along the shaft and carrying a concentrated armature winding and excitation winding and three loaded packets on the rotor arranged on the shaft with a spacial shift of 120 degrees one with relation to the other, and serving for switchover of the flux in the stator, which is distinguished by the fact that, for the purposes of economy of copper, the excitation winding is made up of three concentrated centered coils common to all three stator packets. The generator is distinguished by the use of permanent magnets with magnetic shunts arranged on areas of the stator embraced by the coils of the excitation winding. (Author)
