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.

Silicon Steel Segmented Lamination Bonding And Stacking

In the realm of silicon steel 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 involves carefully treating the surfaces of the electrical steel lamination segments to create a secure and permanent bond without the need for additional adhesives. This approach not only guarantees the structural integrity of the lamination stack but also enhances the overall performance and longevity of the final product.

Simultaneously, our interlocking process employs intricate design and engineering, creating a system in which each segment fits seamlessly into the next. This interlocking mechanism provides added strength and stability to the stack, mitigating the risk of shifting or separation over time.

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 innovative 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.
