ABSTRACT:
A compound series motor includes a series field winding, armature, and auxiliary power supply connected in parallel with the series winding. The drop in armature current through the series field winding may be reduced by connecting an auxiliary field winding having the same polarity as the series field winding between the auxiliary power supply and the main power supply connection to the series field winding so as to prevent an excessive rise in running speed during idle load conditions, while a diode may be connected between the auxiliary power supply and the series field winding connection to the armature to prevent armature current losses. The power supply can be operated to supply continuous excitation current to the series field winding, or be controlled relative to the input voltage, the loading current value, or both the voltage and loading current values to provide an assist-type supplemental excitation current to the series field winding.
