An electrically and mechanically driven automotive accessory including a housing, an electric motor, a pulley, and a pulley assist mechanism. The electric motor comprises a stator assembly that is mounted to the housing and a rotating assembly that is mounted to a shaft. The electric motor creates a primary torque flow path that drives rotation of the rotating assembly relative to the stator assembly. The pulley is rotatable relative to the shaft and the rotating assembly. The pulley assist mechanism includes a plurality of circumferentially spaced teeth nested with a conductive body, a rotor body fixedly mounted to the shaft, and an electromagnet that is configured to induce a magnetic field between the circumferentially spaced teeth, the rotor body, and the pulley, which creates a secondary torque flow path between the pulley and the rotor body.

Methods and systems of controlling the operation of a pump according to a pump operation schedule are described. In one constructions, a pump controller enters a programming mode and monitors a number of inputs received through a user interface while in the programming mode. The programming mode is then exited and a delay time is defined equal to one hour for each input received through the user interface while in the programming mode. A stored pump operation schedule is accessed and operation of the pump is initiated according to the pump operation schedule after a period of time equal to the delay time has elapsed since exiting the programming mode. Operation of the pump is again initiated according to the accessed pump operation schedule every twenty-four hours since the pump operation schedule was last initiated.

A closed-loop system includes a pump driving a fluid through a series of conduits. A control system is included that minimizes pressure fluctuations in a bootstrap reservoir to maintain a desired minimum pressure at the pump inlet. Moreover, the control system reduces a maximum system pressure by reducing the magnitude of pressure fluctuations encountered by the bootstrap reservoir.

摘要:
A submersible pumping system which, in one embodiment, includes a motor, a pump and a control circuit, or unit, coupled to the motor for controlling the operation of the motor is described. Using motor and sensor signals, the control unit detects various conditions within the pumping system and alters motor operation. In an exemplary embodiment, the control unit initiates an oscillation sequence of applying a forward torque for a first preselected period of time, applying a reverse torque for a second preselected period of time, and then repeating the torque applying steps a selected number of times to eliminate an obstruction from the pump.
