Sub-Micron Concentricity
Multi-stage pilot pins and optical-ground die matrices ensure the stator bore and rotor outer diameter share a mathematically perfect center, critical for uniform air gaps.
INDUSTRIAL AUTOMATION MOTOR SOLUTIONS
ULTRA-PRECISION MOTOR CORE STAMPING FOR SERVO & STEPPER MOTORS
Drive the future of industrial robotics, CNC machinery, and smart automation. We engineer high-precision stator and rotor cores that guarantee sub-micron concentricity and flawless slot geometry. Whether you need custom carbide progressive dies for in-house stamping or fully assembled motor core laminations, our solutions ensure rapid dynamic response and zero cogging torque for your motion control systems.
THE MOTION CONTROL CHALLENGE
ACHIEVING FLAWLESS CONCENTRICITY FOR PRECISE POSITIONING
In servo and stepper motors, even a 0.01mm air gap deviation can cause torque ripple, leading to inaccurate robotic positioning and vibration. Achieving such extreme concentricity during high-speed stamping is a massive challenge. By utilizing Sodick wire-cut tungsten carbide punches, we guarantee an absolute tight clearance between the punch and die matrix. This results in perfectly symmetrical, burr-free slots and dead-center bore alignment, maximizing your motor’s torque density and positional accuracy.

EXPERT ANSWERS ON AUTOMATION MOTOR CORES
Have questions about minimizing cogging torque, achieving sub-micron concentricity, or prototyping robotic motor cores? Review our technical FAQs below or contact our engineering team directly.
How do you guarantee concentricity in high-speed servo motor stamping?
We achieve absolute concentricity by machining our tungsten carbide die matrices and punches with multiple-pass Sodick Wire EDMs, achieving ±0.001mm precision. Combined with multi-stage pilot pins in the progressive die, we prevent any material shifting during the press stroke.
Can your progressive dies reduce cogging torque in stepper motors?
Yes. Cogging torque is devastating for stepper motors. We design our dies with automated in-die rotary skewing features, which minutely rotate each rotor lamination during stacking. This skews the magnetic field, effectively smoothing out low-speed torque ripples.
What thickness of silicon steel do you recommend for industrial servo motors?
For standard industrial servos, 0.50mm CRNGO is highly cost-effective. However, for highly dynamic robotic servos requiring rapid acceleration and deceleration with minimal core loss, we strongly recommend 0.35mm premium electrical steel.
Do you support low-volume prototyping for new robotics motors?
Absolutely. We understand that robotics R&D requires extensive testing. We offer precision laser cutting and slow-feed wire EDM prototyping for validation runs. Once your design is locked in, we seamlessly transition you to high-volume progressive die stamping.
