Axial Flux Stator Lamination Stacks Manufacturer

With years of specialized experience in manufacturing high-precision lamination stacks, we’ve dedicated ourselves to mastering the intricacies of axial flux stator laminations. We understand that you’re not just buying steel; you’re investing in the core performance of your innovative designs. We partner with you to turn complex magnetic challenges into tangible, high-performing realities.

Tape-Wound Cores: The Smooth Expressway for Magnetic Flux

At Sino, we employ advanced tension control and proprietary insulation techniques during winding to ensure that each layer remains electrically isolated. Furthermore, we understand the mechanical stresses involved in forming these wound cores into their final, often complex, slotted shapes. Our post-processing treatments, including precision annealing, are designed to relieve these stresses and restore the steel’s optimal magnetic properties, ensuring those lab-condition benefits translate to your real-world motor.

Segmented Stator Cores: Design Freedom Meets Cooling Finesse

Another compelling strategy for crafting an axial flux stator is to build it from multiple, individually laminated segments. The challenge with segmented cores lies in precision and assembly. If segments don’t fit together perfectly, you can introduce unwanted air gaps, increasing reluctance and potentially creating localized magnetic saturation or noise. At Sino, our state-of-the-art stamping and laser-cutting facilities produce segments with exceptionally tight tolerances. We also collaborate closely with our clients on inter-segment locking features and assembly protocols to ensure excellent magnetic continuity across the entire axial flux motor stator. Our rigorous quality control, including advanced optical inspection, guarantees that each segment meets your exact specifications, paving the way for a seamless and high-performing final assembly.

The Material Question: Not All Steel Carries Flux Equally

At Sino, we maintain a comprehensive inventory of high-quality electrical steels from globally recognized mills, including popular grades like M270-35A, M19-29G, and specialized thin-gauge options for high-frequency applications. Our engineers work hand-in-hand with your design team to understand your specific operating conditions – speed range, flux densities, thermal constraints, and cost targets. We can help you navigate the trade-offs. For instance, while a super-thin lamination might look great on paper for eddy current reduction, we can help assess if the added cost and potential reduction in stacking factor provide a genuine net benefit for your specific axial flux motor stator design.

To put this into perspective, consider this illustrative comparison of how material and construction choices might influence key parameters (actual values will vary based on precise design and operating conditions):

Feature	Sino Tape-Wound (e.g., M270-35A, 0.35mm)	Sino Segmented (e.g., M235-35A, 0.35mm)	Alternative: SMC (Not by Sino)
Targeted Core Loss (Typical)	Lower (e.g., 2.8 W/kg @ 1T, 50Hz)	Low-Moderate (e.g., 3.2 W/kg @ 1T, 50Hz)	Higher Hysteresis Component
Eddy Current Suppression	Very Good	Good	Excellent (Isotropic)
Permeability	High	High (Segment-wise)	Moderate
Manufacturing Precision	Sino High Standard	Sino High Standard	Different Process (Molding)
Design Flexibility	Good for Toroidal base	Excellent for Complex Shapes	Very High (Net Shape)
Mechanical Integrity	Excellent	Very Good (Assembly Dependant)	Moderate
Sino Specialization	Core Expertise	Core Expertise	Not a Sino Product

While Soft Magnetic Composites (SMCs) offer isotropic magnetic properties and are sometimes considered for axial flux machines due to their 3D flux capabilities, they generally come with trade-offs like lower permeability and higher hysteresis losses compared to the high-grade laminated steels Sino specializes in. For applications demanding the utmost efficiency and flux-carrying capability from traditional laminations, Sino is your go-to partner.

Beyond the Stack: Sino's Unwavering Commitment to Quality

Manufacturing world-class axial flux stator laminations goes beyond just choosing the right steel and cutting method. It’s about an end-to-end commitment to quality and continuous improvement.

Advanced Stamping & Laser Cutting

Whether your design calls for intricate tooth shapes or ultra-precise segment outlines, Sino’s cutting-edge stamping presses and high-speed laser cutting systems deliver unparalleled accuracy and repeatability, minimizing burrs that can compromise insulation.

Inter-Laminar Insulation

The quality of the insulation coating on each lamination (often an organic or inorganic coating like C5 or C6) and its integrity after stamping and stacking are crucial. We meticulously control our coating application and handling processes to ensure maximum electrical resistance between layers.

Precision Annealing

Sino’s precisely controlled annealing furnaces restore the material’s grain structure, optimizing permeability and minimizing coercivity, which translates directly to lower hysteresis losses in your axial flux motor stator.

Rigorous Quality Control

From raw material inspection to final dimensional checks and magnetic property testing (where applicable), our multi-stage QC process ensures every lamination stack leaving our facility meets or exceeds your specifications. We leverage tools like coordinate measuring machines (CMMs), vision systems, and Epstein frame testing to validate our output.
