These UNIVERSAL MOTOR fans were marketed for either AC or DC current.  The reason for the DC position was the fan would run at higher RPMs on DC current as opposed to AC. Thus the nichrome wind in series with the DC position in an attempt to PRODUCE EQUAL RPM SPEED ON EITHER AC OR DC CURRENT.


THE FAN MOTOR IS DESIGNED TO RUN ON EITHER AC OR DC CURRENT ON EITHER THE AC OR DC SWITCH SELECTIONS.
