Motor Insulation Frames for Stator Assemblies
What Is an Insulation Frame?
Insulation frames, also referred to as insulation bobbins, are structural components
used in motor stator assemblies to separate copper windings from the stator core.
They provide electrical insulation, mechanical support, and dimensional stability
during winding and motor operation.
Materials and Manufacturing
We coordinate the sourcing of molded insulation frames using high-temperature
engineering plastics suitable for motor applications.
- PA66 and PA66 reinforced with glass fiber(PA6/PPS/PBT/LPC)
- Injection molding with dimensional control
- Material selection based on thermal and insulation requirements
Typical Applications
- EV Drive Motors
- E-Bike & Scooter Motors
- Industrial electric motors
- Axial flux motor stators
Our Scope of Support
We do not manufacture insulation frames ourselves.
Instead, we act as a sourcing and coordination partner,
working with qualified molding factories in China.
Design feasibility review based on drawings or samples
Insulation frame sourcing and supplier coordination
Prototype sampling and mass production support
