Electric drive for submarines |
摘要 |
A direct current electric motor marine propulsion system is provided with a pair of shunt wound direct current electric motors which are alternatively connected in a series/parallel circuit configuration. A forward biased diode between the motors in the series circuit, provides for smooth switching characteristics. Fine control of low speed operation is accomplished through the use of a chopper in series with the power source. A contactor connected across the diode provides for reverse current flow during regenerative braking.
