A rotor for a brushless motor is resistant to degradation in alternative fuels and has desirable magnetic properties. A stator for a brushless DC motor includes coils wound both clockwise and counterclockwise around teeth of a back iron. Pairs of the coils are electrically connected in parallel.

Brushless motor system for a vehicle fuel pump

Motor system with magnet for a vehicle fuel pump

A rotodynamic fuel pump in a fuel delivery system for an internal combustion engine including a pump housing, a pump inlet channel extending through the housing allowing fuel to be drawn into the pump, a purge orifice extending through the housing and spaced away from the pump inlet channel, the purge orifice allowing fuel vapor to exit the pump, the purge orifice including a purge inlet, a purge outlet, and a purge channel, where the purge inlet is axially offset from the purge outlet.

Regenerative fuel pump

A fuel pump includes a housing, and a motor. A single sided impeller has first and second impeller flow channels each including a plurality of vanes. The impeller defines a flow passageway extending therethrough. A cover is attached to the housing and has a cover surface that defines first and second cover flow channels. The cover flow channels receive fuel from inlets formed in the cover. The first and second cover flow channels are aligned with the first and second impeller flow channels and receive fuel through the inlets and deliver fuel to outlets. A body is positioned within the housing and defines an impeller chamber to receive the impeller, and a first outlet passageway fluidically connected to the first cover flow channel and impeller flow channel. A second outlet passageway formed within the cover is fluidically connected to the second cover flow channel and impeller flow channel.

Fuel pump having dual single sided impeller

The present invention provides a system for controlling the speed of a motor by altering the magnetic field of the motor. The system includes field modification module, and a motor having field windings and a rotor. The field windings are configured to receive a driving signal that generates a magnetic field causing a rotation of the rotor. The field modification module is proximate the motor and alters the magnetic field in response to an input signal thereby controlling the speed and torque of the rotor.

System for controlling motor speed by altering magnetic field of the motor

A fuel pump is provided having improved efficiency by lowering the wet circle index of the pump while maintaining robust axial clearances to meet the demands of an automotive application. One embodiment includes a fuel pump for pressurizing fuel for delivery to an engine of a motor vehicle. The fuel pump generally comprises a housing, a motor, a single sided impeller, a cover and a body. The provision of a single sided impeller greatly reduces the wet circle index and improves the pump efficiency. The cover, impeller, and body are structured to axially balance the impeller which is free floating on the shaft of the motor.

Fuel pump having single sided impeller

An automotive fuel pump housing for a fuel pump encases a rotary pumping element. The housing has two portions, a cover and a bottom. The cover has an inlet port which defines a directional control surface having an inclined frustoconical portion and an inclined planar portion conjoined therewith and laterally extending therefrom such that fuel flowing over the inclined frustoconical portion accelerates primarily radially and combines with fuel flowing primarily axially over the inclined planar portion, whereby the combined flow is smoothly directed to an annular cover channel. The bottom has an annular bottom channel which, when the cover and bottom are assembled, the annular cover channel and annular bottom channel cooperate to form the inlet channel. A transition section is located at the beginning of the inlet channel and extends along a portion of the arc of the inlet channel. The transition section decreases in depth from a maximum depth at the beginning thereof to the depth of the remaining portion of the inlet channel. The annular cover channel has a two-step transition section depth whereas the annular bottom channel has a single-step transition section depth. In addition, the radius of the base circle of the inlet channel outside of the transition section is not less than the radius of the rotary pumping element near the vane grooves.
