Segmented Stator Lamination
We stamp highly precise individual stator teeth (segments) that allow OEMs to use concentrated windings, drastically increasing the copper fill factor before final assembly.
BRUSHLESS DC MOTOR SOLUTIONS
HIGH-EFFICIENCY BLDC MOTOR CORE STAMPING & MANUFACTURING
Powering the next generation of smart appliances, HVAC systems, and micro-mobility. We specialize in ultra-precision stamping for Brushless DC (BLDC) motor stators and rotors. Utilizing high-grade, ultra-thin silicon steel and our sub-micron tungsten carbide progressive dies, we minimize high-frequency core loss and guarantee absolute concentricity. Choose our mass production services to achieve maximum power density in a compact footprint.
THE EFFICIENCY CHALLENGE
MINIMIZING HIGH-FREQUENCY EDDY CURRENTS IN BLDC MOTORS
High-speed BLDC motors, often exceeding 100,000 RPM in applications like vacuum cleaners and drones, generate severe heat due to high-frequency eddy currents. The solution is stamping ultra-thin electrical steel (0.20mm – 0.35mm). However, microscopic burrs caused by rapid die wear can bridge the laminations, short-circuiting the stack and destroying efficiency. Our optical-ground carbide tooling maintains a strict <0.01mm burr clearance over millions of strokes, ensuring pristine lamination insulation and whisper-quiet motor operation.
PRECISION ENGINEERING
ADVANCED CORE ASSEMBLY FOR BRUSHLESS DC MOTORS
From concentrated windings to ultra-tight air gaps, our progressive stamping capabilities are engineered to unleash the full potential of your BLDC motor designs.
PREMIUM MATERIALS
OPTIMIZED SILICON STEEL FOR HIGH-SPEED SWITCHING
BLDC motor controllers switch magnetic fields at incredibly high frequencies. To prevent massive core losses, the silicon steel must be exceptionally thin with high resistivity. We source premium ultra-thin CRNGO directly from Baosteel and Nippon Steel, ensuring your BLDC motors stay cool even under continuous high-load operations.

EXPERT ANSWERS ON BLDC MOTOR CORES
Have technical questions about segmented stators, ultra-thin material stamping, or bonding techniques for BLDC rotors? Review our FAQs below or contact our engineers to optimize your motor design.
Why are BLDC motor cores more difficult to stamp than traditional AC motors?
BLDC motors demand significantly higher efficiency, which requires stamping ultra-thin silicon steel (e.g., 0.20mm – 0.35mm) to reduce high-frequency core loss. This thin material is highly abrasive and prone to burring, requiring exceptionally precise tungsten carbide dies with sub-micron clearances that most traditional stamping shops cannot manufacture.
Can you stamp segmented (split) stators for high-torque BLDC motors?
Yes. Segmented stators are highly popular in modern BLDC designs because they allow for concentrated winding, massively increasing the slot fill factor. We build highly precise progressive dies that stamp these individual stator teeth with flawless interlocking geometries for easy final assembly.
What thickness of silicon steel is best for a 100,000+ RPM BLDC motor?
For extreme high-speed applications like drone motors or high-speed hair dryers (100k+ RPM), Eddy current losses become severe. We strongly recommend using 0.20mm or 0.30mm premium CRNGO steel to keep the motor running cool and efficiently.
Do you offer rapid prototyping for new BLDC motor designs?
Absolutely. We offer precision wire-EDM and laser cutting services to produce low-volume BLDC core prototypes. This enables your team to wind the coils, test the back-EMF, and validate the magnetic performance before investing in a mass-production progressive die.
