Both methods are applicable to general purpose, general industrial mill motors, and special purpose direct-current machines. This includes constant-speed and adjustable-speed motors and machines with and without compound windings, and with and without compensating windings. 517 $aAIEE No. 66-1957 606 $aElectric generators$xDirect current 606 $aDC-to-DC converters 606 $aElectric current converters 615 0$aElectric generators$xDirect current. 615 0$aDC-to-DC converters. 615 0$aElectric current converters. 676 $a621.3132 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910136383903321 996 $aAIEE No. 66-1957$93647553 997 $aUNINA
