INTEGRATED ELECTRIC VANE OIL PUMP

摘要

An electric vane pump includes a first cover plate having a substantially planar first pump surface and a second cover plate coupled to the first cover plate defining a substantially planar second pump surface spaced apart from and extending substantially parallel to the first pump surface. A plurality of permanent magnets are fixed to a rotor. A plurality of radially moveable vanes are fixed for rotation with the rotor. Each vane is positioned between the first and second pump surfaces and has a first end slidably engaging the center vane support. An electric motor stator is positioned between the first and second cover plates and circumscribes the rotor. A resilient member biases each of the vanes into engagement with the center vane support.
