Insulated Stator Core with Interlaminar Insulation and Low Core Loss Design for Precision Stator Lamination

Our Insulated Stator Core is a precision-manufactured motor core component designed for electric motors, generators, EV drive systems, industrial motors, and other electromagnetic applications. Manufactured from high-quality silicon steel (electrical steel) laminations, the stator core is engineered to support efficient magnetic flux distribution while helping reduce electrical losses in suitable motor designs.

The stator core is assembled from multiple thin electrical steel laminations. An insulating coating between individual laminations helps electrically separate adjacent layers and can reduce circulating eddy currents within the core. Combined with precision stamping, controlled lamination geometry, and accurate stacking, this construction supports stable electromagnetic performance and consistent motor manufacturing quality.

Our precision silicon steel motor cores can be produced according to customer drawings, 2D/3D CAD files, samples, or specific electromagnetic and mechanical requirements. The lamination profile, slot geometry, outer diameter, inner diameter, stack height, tooth structure, ventilation features, and other dimensions can be customized for different motor platforms.

An insulated stator core is a motor stator structure assembled from multiple electrical steel laminations with insulating layers or coatings between the laminations. The insulation helps electrically separate adjacent laminations and can reduce eddy-current-related losses.

The main material is generally silicon steel, also known as electrical steel. Different grades and lamination thicknesses can be selected according to the motor's magnetic and efficiency requirements.

Insulation between laminations helps reduce electrical current circulation between adjacent steel sheets. This can help reduce eddy current losses and support efficient motor operation.

Depending on the material and application, lamination thickness can typically range from approximately 0.15mm to 0.65mm. Custom thicknesses can be evaluated according to project requirements.
