AI Technical Summary

Problems solved by technology

The cable lines coupling the remotely located electronic controller to the electric motor can sometimes be used as antennas to pick up electromagnetic interference that may adversely interfere with the intended operation of the electric motor and / or the possible operation of the electronic controller
With the large number of electronic devices now used in contemporary motor vehicles, many of which can emit electromagnetic interference, this has become an increasing challenge for vehicle designers
Furthermore, it is often not possible to route the electrical cabling between the G-rotor motor and the controller in such a way as to ensure that electromagnetic interference is not a problem

Abstract

A G-rotor pump assembly is disclosed. The assembly makes use of a housing having a pump / motor housing portion and a laterally projecting housing portion. An electric motor is disposed within the pump / motor housing portion. A controller has a circuit board with a portion which is positioned within the pump / motor housing portion so as to be generally axially aligned with the electric motor and in proximity to the electric motor. A lower cover is configured to engage with the housing to encapsulate the controller and the electric motor within the housing.

Description

technical field [0001] The present disclosure relates to pumps, and more particularly, to G-rotor pumps commonly used in motor vehicle applications. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Electric motor driven pumps, and especially Gerotor type pumps (hereinafter "G-rotor" pumps), are often used in a wide variety of applications, and are especially associated with motor vehicles. In particular, G-rotor pumps are often used as fuel pumps, oil pumps with hydraulic motors and power steering units, just to name some motor vehicle related applications. [0004] Typically, the G-rotor subsystem is driven by a motor, usually an electric motor, but sometimes by a drive shaft or other form of output shaft. When an electric motor is used as the drive, the motor is usually controlled by an electronic controller located on a separate circuit board or...
