Precision Aerospace Motor Lamination Solutions
Thomson Lamination Company (TLC) delivers precision aerospace motor laminations engineered for the rigorous demands of critical flight systems. TLC supports aerospace manufacturers with high-performance laminations built for durability, compactness, efficiency, and absolute precision.
Our aerospace motor lamination capabilities extend from prototype development to full-scale production. Every part we produce is shaped by decades of experience, advanced stamping and machining technologies, and a deep understanding of aerospace-grade materials. With quality systems certified to AS9100 and specialized NADCAP heat treating and welding capabilities, TLC delivers components that consistently exceed expectations and industry requirements.
Aerospace-Grade Materials and Specs
Cobalt-Iron and Nickel-Iron Alloys
TLC uses some of the most advanced magnetic materials available to support efficient, high-performance electric motors for aerospace applications. We work with iron-cobalt alloys to achieve magnetic saturation levels up to 24 kilogauss and low core loss. This makes them ideal for high-speed, high-torque aerospace motors.
We also work with nickel-iron alloys, which are prized for their high magnetic permeability and low core loss. These materials allow engineers to achieve maximum electromagnetic performance, crucial for components in aircraft systems where power density, efficiency, and thermal stability are critical.
Magnetic and Mechanical Properties
The alloys we use are chosen for their mechanical durability and performance under extreme conditions. These materials exhibit low coercivity, high resistivity, and excellent dimensional stability. All this allows them to maintain performance in harsh aerospace conditions, including rapid temperature fluctuations, high vibration, and sustained stress.
Material Certifications
Every material TLC uses in aerospace motor laminations is fully traceable and compliant with industry standards such as REACH, RoHS, DFARS, and conflict minerals regulations. This not only ensures ethical, environmentally responsible sourcing but also gives our aerospace clients peace of mind when meeting procurement and reporting requirements for government and international contracts.
Tight-Tolerance Stator and Rotor Assemblies
Precision Machining Accuracy
Aerospace components demand utmost precision. At TLC, our stamping and machining processes routinely hold tight tolerances. We use advanced CNC systems, state-of-the-art progressive dies, and advanced stamping presses to produce laminations and lamination stacks that meet the stringent fit and function requirements of aerospace programs worldwide.
Our inspection and quality assurance protocols are built for critical aerospace applications. Components are checked for concentricity, flatness, FOD (foreign objects & debris), and dimensional consistency throughout each production run.
Assembly Capabilities
Our rotor and stator stack assembly capabilities include bonding, riveting, and a NADCAP certified welding process. These processes create lightweight yet durable assemblies that perform reliably amid extreme thermal cycles, vibrations, and other operational environments.
Whether your design requires torque-dense rotors for electromechanical actuators or thin-gauge laminations for compact stator assemblies, our engineering team will work closely with you to meet your exact specs.
Component Types for Aerospace
TLC produces a broad range of aerospace electric motor laminations and assemblies, including components used in:
- Electric Actuators
- Braking Systems
- Power Generation Units
- Fuel Pump Systems
- Landing Systems
AS9100 and NADCAP Heat Treating
Certified Heat Treatment Process
As part of our commitment to compliant aerospace manufacturing, TLC operates a NADCAP-accredited heat treatment facility. Our team applies tightly controlled heat treating cycles that enhance material grain structure, relieve internal stress, and improve magnetic properties without compromising tight tolerances.
Hydrogen Atmosphere Batch and Bell Retort Annealing
Our capabilities include hydrogen atmosphere batch and bell retort annealing—processes essential to producing clean, bright, and stress-relieved laminations. These treatments are performed in inert or reducing environments to eliminate surface oxidation and improve uniformity of magnetic response and mechanical properties across all parts.
Stress Relief Annealing for Dimensional Stability
Stress relief annealing is a core part of our aerospace lamination workflow. These processes minimize internal mechanical stress caused by slitting and stamping and operations, resulting in parts with consistent dimensions and predictable behavior under demanding service conditions.
