1. A submersible water pump device, comprising:

  • a motor, wherein the motor includes a stator and a rotor positioned within the stator on a shaft, and wherein the stator is connected to windings that energize the stator to produce a rotating magnetic field that produces a torque on the rotor causing rotation of the rotor;

    an impeller with curved blades connected to an end of the rotor on the shaft, wherein the impeller with curved blades is used to increase an amount of water discharged from the submersible water pump device; and

    a control circuit that includes a motor control circuit to control running of the motor in the submersible water pump device, wherein the motor control circuit includes control logic for determining when and when not to run the motor.
