  • Electric motor for fuel pump with improved shutdown features
    Patent number: 8209107
    Abstract: An electric motor for a fuel pump is provided with a shutdown switch positioned intermediate an inverter, and its control coil. In this location, the shutdown function can be achieved without heavy components. In another feature, when the fuel pump is shut down, a signal is sent upstream to a voltage regulator associated with a generator, such that the voltage supplied downstream by the generator can be reduced to eliminate any potential voltage spike due to the shutdown of the electric motor. The electric motor with shutdown switch enables low weight fault tolerant flux regulated machines.
