Abstract: An electric motor is configured to provide mechanical power to a fuel pump. A method for monitoring the fuel pump includes estimating a pump speed and a nominal pump motor current in relation to a pump motor control signal and a fuel pressure. An armature resistance and a back-emf constant for the electric motor are determined corresponding to the estimated pump speed, a monitored pump motor current, and the pump motor control signal. A nominal armature resistance and a nominal back-emf constant for the electric motor are adjusted in relation to a pump motor temperature. A plurality of residuals are calculated based upon the adjusted nominal armature resistance, the adjusted nominal back-emf constant for the electric motor, the estimated armature resistance and the estimated back-emf constant for the electric motor. The residuals are compared with corresponding thresholds. A fault in the electric motor is detected based upon the comparisons of the residuals with the corresponding thresholds.

Abstract: A self-priming diaphragm pump is connected to a circuit board which activates the self-priming diaphragm pump at predetermined intervals, e.g., for 1-3 seconds. When the self-priming diaphragm pump is activated, the circuit board senses the amperage draw from the pump's motor and either continues to run the pump or stops the pump depending on the different amperage levels read. If there is water present in the bilge, the motor is working harder, requiring more amperage and circuit board keeps the pump running. If there is no water present for the pump to draw, the amperage load is very low and the circuit board shuts the pump off, retesting it in the predetermined interval.

Abstract: A variable speed motor controller senses the electrical load on the motor in turning a pump. An output of the controller may be used to trigger a vent valve or power to the motor may be cut if the load level indicates a restricted flow of fluid into the suction side of the pump, such as would be caused by drain occlusion in a swimming pool. A sensor in communication with the suction side of the pump ascertains a vacuum/pressure level present and may be used to verify that an intended operational state for the variable speed motor and the pump is actualized, otherwise anomaly processing is invoked. This pressure/vacuum monitoring may be conducted through speed changes of the motor/pump.

Abstract: Disclosed is a method of controlling an inverter-integrated electric compressor for a vehicular air conditioning system, which prevents an over-current from being generated due to a load of an inverter for driving the electric compressor and reduces an RPM even without stopping the vehicular air conditioning system, preventing damage to the air conditioning system due to an over-current. The method of controlling an inverter-integrated electric compressor for a vehicular air conditioning system includes the steps of: (1) calculating a target RPM of a motor for driving the inverter-integrated electric compressor in a vehicular air conditioning system; (2) checking whether a current applied to the motor driven according to the target RPM exceeds a threshold value preset in the inverter; and (3) decreasing, if the current applied to the motor exceeds the threshold vale, the target RPM in the inverter to perform a feedback control of reducing the current, and rotating, if the current applied to the motor does not exceed the threshold value, the motor according to the target RPM.

Abstract: A method is provided for the electrical protection of an electrical household appliance that is used to prepare food. The appliance includes an electric pump which is supplied with alternating current in order to convey a liquid through a conduit, and a heating element to raise the temperature of the liquid. The instantaneous value of the current I supplied to the pump is measured at regular time intervals. The method includes calculating the average value αn of m current I measurements taken over a pre-determined time period T; comparing the average value αn with a reference value αref calculated as the average value of the current I measurements taken over an earlier period of the same length; and opening the pump's power supply circuit when the difference between the average values αref and αn exceeds a pre-determined threshold value Δ1 for at least two successive time periods T as a result of low average current indicative of dry running.

Abstract: Embodiments of the invention provide a stand-alone controller and a method for controlling a pump motor driven by an alternating current source. The stand-alone controller includes a power terminal for connection with the alternating current source and a load terminal for connection with the pump motor. The stand-alone controller further includes an enable switch to form a power line carrying power from the alternating current source to the pump motor. The stand-alone controller can store a first current being drawn through the power line by the pump motor when a control switch is actuated. A state of the enable switch is based on a comparison of the first current to a second current being drawn through the power line by the pump motor.
