Insulation Parts and Molded Parts for Electric Motors and Generators

Gotthardt Isolierteile GmbH has been manufacturing high-quality insulation parts and molded parts from polyester films (PET) and other proven electrical insulation materials for over 60 years. They are among the safety-critical components in electric motors and generators: they prevent electrical flashovers and thus ensure the service life and operational safety of the machines. Our customers benefit from fast delivery times, ISO-certified quality and custom solutions.

What Are Insulation Parts and Molded Parts?

Insulation parts are electrically non-conductive components that are precisely integrated into motors and generators. While stamped parts are two-dimensional, molded parts are created by applying force to a flat material to permanently form it into a three-dimensional geometry.

With modern embossing and folding tools, we realize a wide variety of angles, shapes and dimensions. Uniform and permanent embossing ensures that the components remain load-bearing throughout their entire service life.

Applications of Insulation Parts and Molded Parts

Dimensions range from the smallest insulation components for fan motors through medium-sized molded parts for industrial drive technology to large-format components for wind power generators.

Materials for Insulation Parts

All materials are converted according to customer specifications and meet common standards and UL listings.

Knowledge from our glossary

Technical fundamentals and term explanations on this topic.

  • Slot Insulation

    Slot insulation is the insulation of stator slots in electrical machines to protect the windings from mechanical damage.

  • Field Coil Insulation

    Field coil insulation refers to insulating layers and components that electrically separate field coils from the pole core, enclosure and adjacent windings.

  • Turn Insulation

    Turn insulation is the first insulation layer in electrical machines, electrically separating individual conductor turns from one another.

  • Armature Insulation

    Armature insulation is an insulating part that electrically separates the copper wire from the lamination stack of the armature and protects it mechanically.

  • Form Coils

    Form coils are preformed windings brought into their final geometry in a defined tool before being installed in electrical machines.

  • Insulating Paper

    Insulating paper is a flat electrical insulating material of cellulose or aramid fibres, alone or laminated with film, that separates winding and core in motors and transformers and, depending on type, insulates continuously from 105 °C (pressboard) to 220 °C (aramid paper Nomex 410).
