Abstract
PURPOSE: To produce this field circuit of an electromagnetic coupling with a narrow adjusting range, by mounting resistance that can be connected and disconnected in parallel with field winding.
CONSTITUTION: The output of a three-phase full-wave rectification circuit 6 is connected to the field winding 1 of an electromagnetic coupling through series resistance 3 while a series circuit of parallel resistance 2 and a switch 4, which is contacted and detached by means of a field current detector 5, is connected in parallel with the field winding 1. When continuously decreasing field currents, the making instructions of the switch 4 are emitted from the detector 5 when the field currents reach not more than some value, and the parallel resistance 2 is closed. The three-phase full-wave rectifier 6 works so as to raise the field currents in order to let the same currents flow to the field winding 1. A range that the output of the three-phase full-wave rectifier 6 is adjusted can be controlled in small one because field voltage in a region that the field currents are little can be increased by the connection of the parallel resistance 2.
