Custom T-Motor Stator Stacks Electric Motor Lamination

Segment laminations, also known as T-segment laminations, is the iron core is divided into several parts and then through the special groove type of stitching into a whole core, the use of this way to process the iron core can obtain a high slot full rate while saving raw material costs, especially the size of the relatively large laminated iron core products.

Segmentation of the stator may lend itself particularly well to electrical machines in automotive applications, aerospace, robotics, or renewable energy.

T-Shaped Stator Core Electric Motor Lamination Stacks Stamping

Motorneo delivers top-quality motor laminations is the utilization of a high-efficiency, high-speed stamping process. This process typically utilizes progressive stamping machinery and molds capable of producing each segment motor core with tight tolerances efficiently.

Progressive stamping dies combined with interlocked to improve overall efficiency. It is economical for mass production of the motor lamination stacks.

The segmented stator laminations are widely used in electric vehicles and hybrid electric vehicle motors to enhance heat thermal.

Silicon Steel Segmented Lamination Bonding And Stacking

For the segmented lamination bonding and stacking, we utilize both a self-bonding process and an interlocking method to assemble silicon steel lamination segments.

Silicon Steel Segmented Laminations Bonding And Stacking

Our self-bonding process uses silicon steel sheets coated with adhesive varnish. At certain temperatures and pressures, the silicon steel laminations will self-bond without additional adhesives.

The interlocking process is carried out in a progressive stamping die, and the interlocking points of each motor stack are interlocked layer by layer to form a completed motor core segment. The segmented iron core is spliced together by a dovetail groove or welding process to form a complete circular motor laminate pack.

In addition, Motorneo also offers riveting, laser welding, TIG+MIG welding, cleating, and gluing to bonding and stacking rotor and stator lamination.

Electrostatic Epoxy Insulation Coating Segmented Stator

Motorneo has electrostatic epoxy insulation coating technology for segmented stator cores.

This process involves applying a highly resilient and electrically insulating epoxy coating to the segmented stator core.

This coating not only provides a robust layer of protection, preventing electrical shorts and potential damage, but also ensures the longevity and reliability of the stator core in various demanding applications.

Electrostatic coating application guarantees an even and consistent layer, adhering tightly to the core’s intricate geometries. This insulation technology contributes to enhanced motor performance, reduced energy loss, and improved durability.

Segmented Stator Windings

Unlike traditional continuous windings, the segmented stator winding process focuses on a single core segment to concentrated winding. Wrap insulated copper wire coil around each segment of the motor core providing greater flexibility and efficiency in motor operation.

Motorneo full automatic segmented winding machines can improve production efficiency and can wind 20 – 100 sets of stators per day. The segment winding design enhances cooling efficiency, reduces eddy current losses, and improves overall motor reliability.

Quality Control For Motor Lamination Stacks

Quality control is paramount in ensuring the reliability and performance of segmented motor lamination stacks. Here’s a list of key quality control measures for these components:

quality control


Rigorous inspection of the raw materials, particularly the silicon steel sheets, for quality, thickness, and magnetic properties.


CMM precise measurement of each segment to ensure adherence to design specifications and tolerances.


Testing the integrity of the bonding in self-bonded laminations to ensure a secure and durable connection.


Inspection of the electrostatic epoxy insulation coating for uniformity, ensuring comprehensive electrical insulation coverage.


Maintaining detailed records of each manufacturing step and ensuring traceability to identify and address any issues in the production process.

Segmentation lamination stacks FAQs

Working with segmented stacks provide enhanced cooling, reduced eddy current losses, and the ability to tailor designs for specific motor requirements, optimizing overall efficiency and reliability.

The primary material commonly used for these segment electrical laminations is silicon steel, also known as electrical steel, lamination steel, or transformer steel. Silicon steel is preferred for its magnetic properties, which include high permeability and low core hysteresis loss. We also new materials such as amorphous alloys to manufacture segmented lamination cores.

Segmented lamination stacks represent an innovative approach to the construction of stator cores in electric motors. Unlike traditional laminations, which consist of continuous sheets of magnetic material, segmented lamination stacks are comprised of individual, precisely engineered segments.

These segments are strategically arranged and bonded together to form the stator core. The key distinction lies in the flexibility and customization that segmented stacks offer. This design allows for tailored configurations, optimizing performance and efficiency based on specific motor applications.
