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
- Slot insulation and slot linings: Prevent flashovers between windings and lamination stack
- Slot wedges, phase separators and slot caps: Ensure safe separation and stability
- Armature insulation: Protects electrical windings
- Field coil insulation: Ensures operational safety even under high thermal load
- Insulation for form-wound coils: For motors and generators of every size
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
- Polyester films (PET, e.g. Hostaphan, Mylar)
- Polyimide films (e.g. Kapton)
- Aramid paper (e.g. Nomex)
- Pressboard and technical laminates (e.g. NMN, DMD)
- Glass fiber and mica for the highest temperature resistance
All materials are converted according to customer specifications and meet common standards and UL listings.
