  • Publication number: 20060232143
    Abstract: Devices and methods are provided for an improved motor stator. One embodiment for a stator includes a stator section having a first surface and a second surface each surface having a groove extending into the stator section and a slot extending longitudinally between the first and second surfaces. Insulated conductive wires are wound longitudinally around the stator section in the slots to form winding turns contained completely within each groove. A lead frame extends circumferentially along a surface of the stator and the insulated conductive wires couple to the lead frame. A thermoset material is supplied to the stator section to encapsulate the stator section including the lead frame and the insulated conductive wires, and to provide integral coolant flow passages.

  • Publication number: 20050133752
    Abstract: A miniature solenoid valve including a housing defining an axial passage with a valve seat formed integral with the housing and including a minute flow orifice in fluidic communication with the axial passage. A magnetic actuator is positioned within the axial passage and is adapted for reciprocating movement along an actuation axis. A valve element is engagable with the integrally formed valve seat to substantially prevent flow through the minute flow orifice in response to displacement of the magnetic actuator along the actuation axis. In another embodiment, a connection element is formed integral with the housing and is configured for sealing engagement with a pressurized flow source to supply flow to the flow orifice. In a further embodiment, the housing defines a closed end and an open end, with a pole piece engaged with the valve housing and including a transverse portion covering the open end of the valve housing.
