Problems solved by technology

One drawback associated with many conventional electric water pumps is the need for a rotor encoder or other type of speed sensor within the electric motor to facilitate precise low speed (i.e., less than 600 RPM) pump control via a closed loop motor control system

Abstract

An electric water pump is disclosed having a motor with an axially moveable rotor unit. A rotary pump member is fixed for axial movement with the rotor unit to vary its position within a pump chamber so as to vary the flow rate through the pump chamber.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 140,854, filed March 31, 2015. The entire content of the above application is incorporated herein by reference. technical field [0003] The present disclosure generally relates to water pumps for motor vehicles. More specifically, the present disclosure relates to variable flow electric water pumps equipped with axially movable rotor / impeller assemblies. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Water pumps are known to be commonly used in motor vehicles as part of a thermal management system for pumping fluid coolant to facilitate heat transfer between the coolant and the internal combustion engine during vehicle warm-up and operation. Most commonly, centrifugal water pumps having a rotating pump member such as an impeller ar...
