Precision-Grade M350-50A Silicon Steel Laminations – Ultra-Thin (0.5mm) Grain-Oriented Cores for High-Efficiency AC Motors with <0.8W/kg Iron Loss

Product Description:

Our motor laminations are engineered from high-grade, grain-oriented silicon steel that keeps eddy-current losses exceptionally low—under 1.2 W/kg at 1.5 T and 50 Hz—so your machines run cooler and more efficiently. A proprietary, precision-controlled annealing cycle realigns the crystal lattice, boosting peak magnetic flux density to 1.8 T and sharply cutting harmonic distortion, which translates into higher torque with quieter operation. Each lamination is supplied with a uniform, high-dielectric insulation coating applied in-line at the mill; this “stack-ready” finish eliminates the need for post-varnishing and reduces stator or rotor build time by roughly 40 percent. The result is a lightweight, low-loss core that raises motor efficiency, simplifies assembly, and delivers long-term reliability in demanding applications—from high-speed traction drives to compact HVAC compressors.

Features:

⚡ Low Core Loss — Up to 30 % lower than standard laminations
Our grain-oriented silicon-steel stack keeps hysteresis and eddy-current losses to an absolute minimum, delivering a cooler-running, higher-efficiency motor—especially at the elevated switching frequencies typical of modern drive inverters.

⚡ High Saturation Flux — Engineered for demanding EV traction duty
With a saturation flux density approaching 1.8 T, the laminations maintain torque under peak load and high RPM, allowing designers to shrink active‐material mass without compromising power output.

⚡ Custom Geometry — Ready for skewed, helical, or stepped slots
Precision laser blanking and progressive-die stamping support intricate tooth profiles and axial skews that mitigate cogging torque, reduce acoustic noise, and smooth electromagnetic torque ripple.

⚡ Integrated Vibration Damping — Multi-layer adhesive bonding option
An optional viscoelastic inter-layer bonding system sandwiches each lamination in a micro-thin damping film, suppressing structure-borne vibration and cutting overall motor noise by up to 6 dB while improving mechanical robustness during high-speed operation.

Applications:

Sector Typical Use-Case Why Our Laminations Stand Out
Electric-Vehicle Drivetrains Main traction motors, e-axles, integrated starter–generators - 30 % lower core loss extends driving range and keeps batteries cooler, while 1.8 T saturation flux maintains torque during hard acceleration and hill climbs.
Precision Industrial Servo Motors Robotics, CNC, pick-and-place actuators Ultra-low hysteresis loss improves position accuracy and thermal stability; skewed-slot capability minimises cogging for silky-smooth motion control.
HVAC Compressor Units Scroll, rotary, and centrifugal compressors Stack-ready insulation slashes assembly time by 40 %; adhesive-bonded laminations damp vibration, reducing audible noise in residential and commercial spaces.
Wind-Turbine Generators Direct-drive and geared PM generators High flux density allows compact stator designs, while grain-oriented steel cuts loss at variable frequencies, boosting annual energy production.
 

Customization:

Category Available Choices Benefits to Your Project
Core Shapes Circular stator/rotor rings
Segmented arc segments for large-diameter windings
Rectangular / racetrack blanks for linear motors and transformers
Match any topography, from compact traction motors to utility-scale generators, while minimising scrap and tooling cost.
Slot Patterns Closed-slot designs for maximal flux containment and low leakage
Semi-closed slots that balance winding accessibility with magnetic performance
• Fully skewed or helical variants to cut cogging torque
Optimise the electromagnetic signature—higher power factor, quieter running, and smoother torque ripple—without redesigning the entire stator stack.
Post-Processing Finishes Phosphating for enhanced paint adhesion and corrosion resistance
Electroless nickel plating for superior conductivity shielding and salt-spray durability
Extend service life in harsh environments such as coastal wind farms, EV powertrains exposed to road salts, or high-humidity HVAC systems.
 

Support and Services:

Our Product Technical Support and Services for the Sheet Metal Progressive Die include:

Packing and Shipping:

Product Packaging:

The Sheet Metal Progressive Die product will be carefully wrapped in protective material to prevent any damage during transportation. It will then be placed in a sturdy cardboard box with adequate cushioning to ensure its safe delivery.

Shipping:

Once the Sheet Metal Progressive Die product is securely packaged, it will be shipped via a reliable courier service. Customers can track their shipment using the provided tracking number to monitor its delivery status.

 

FAQ:

Q 1: What is the minimum order quantity for custom stamping dies?
A: The minimum order for each design is 5,000 pieces. After receiving the final drawings, the mold making and the confirmation of the first piece will be completed in approximately 15 working days.
Q 2: Can small-batch trial production be provided before mass production?
A: OK. After the mold is accepted, a trial production batch of 200 to 300 pieces can be delivered first to facilitate your installation and testing.
Q 3: Will the insulating coating reduce the heat dissipation performance?
A: According to the test of IEC 60404-8, the coating reduces the vertical thermal conductivity by less than 3% and has almost no effect on the core heat dissipation.
Q 4: What are the optional thicknesses of silicon steel sheets?
A: Always have 0.20mm, 0.27mm, 0.35mm on hand; Thinner specifications can be supplied on demand.
Q 5: Can laminated components that have been bonded or welded be provided?
A: Yes, it supports various full-stack delivery forms such as adhesive bonding, laser welding, and interlocking with clips.
