    Nomex Shaped Wedges for Motor Stator Insulation

    Nomex shaped wedges are Class 180°C curve formed insulation profiles used for motor rewinding, stator slot insulation and coil retention applications.

    Manufactured from Nomex insulation material, they provide excellent electrical performance, durability and resistance to wear in demanding motor repair environments.

    Product Summary
    Curve formed Nomex wedge profiles for electric motor slot insulation. Available in multiple profile sizes and wall thicknesses including .020", .024" and .030".

    Standard Wedge Length: 36" (914.4mm)
    Supplied In: Bundles of 250 feet (76.2 metres)
    Stocked Profiles
    We currently stock selected .020" wall Nomex shaped wedge profiles for faster supply and common motor rewinding applications:

    GN7020  |  GN8620  |  GN9920  |  GN11720  |  GN14420  |  GN19920

    Other profiles and wall thicknesses may still be available, however extended lead times can apply depending on the wedge profile required.
    Class 180°C Insulation
    Suitable for high-temperature motor insulation applications requiring reliable thermal endurance.
    Curve Formed Profiles
    Shaped wedge profiles designed to fit motor slot applications and assist with winding retention.
    Motor Rewind Applications
    Commonly used by motor rewinders for stator insulation, coil retention and electrical repair work.
    Common Applications
    • Electric motor rewinding and repair
    • Motor stator slot insulation
    • Coil retention in winding slots
    • Generator and alternator insulation systems
    • Industrial motor maintenance workshops

    If you are matching an existing wedge profile, please provide the current wedge dimensions, wall thickness or a clear photo/sample where possible. This helps us identify the most suitable Nomex shaped wedge profile for your application.
