What Are Laser Cut Stator Laminations?
Laser cut stator laminations are thin sheets of electrical steel (silicon steel) cut into stator core shapes using a focused laser beam rather than a mechanical stamping die. The laser follows a digital CAD profile, cutting slots, teeth, and mounting features with high precision — no physical tooling required.
Laser cutting is particularly valuable for UAV motor development because it eliminates the need for hard tooling. Engineers can iterate on slot geometry, tooth width, or outer diameter without waiting for a new die. Key characteristics include:
- No tooling cost — ideal for prototypes & low volume
- Fast turnaround — days instead of weeks
- Design flexibility — easy to modify CAD and re-cut
- Burr-free edges with optimized laser parameters
For production volumes, laser cutting can be paired with stamping — use laser for prototyping, then transition to stamping once the design is frozen.
Laser cut stator laminations — precision cutting with no tooling cost, ideal for UAV motor prototyping.
Types & Cutting Methods for Stator Laminations
Stator laminations can be produced by several methods, each with distinct trade-offs. Reenives offers the following:
- Laser Cut Laminations — No tooling cost, fast turnaround, high design flexibility. Best for prototypes, low volume, and design iterations.
- Stamped Laminations — High-speed stamping with hard tooling. Lowest cost per piece at high volumes, but requires tooling investment and longer lead time.
- Wire EDM Laminations — Extremely precise cutting for exotic shapes or hard materials. Slower and more expensive than laser for most stator profiles.
- Waterjet Laminations — Cold cutting process with no heat-affected zone. Suitable for thick materials, but slower and less precise than laser for thin laminations.
- Chemical Etched Laminations — Photochemical machining for burr-free, stress-free cutting. Good for very thin laminations but limited to smaller sizes.
For UAV motor development, laser cutting is often the fastest path from CAD to testable stator stack. Reenives can also transition your design to stamping for mass production.

How to Select the Right Laser Cut Stator Laminations
Choosing the right cutting method and lamination design for your UAV motor involves several engineering decisions. Follow these steps:
- Determine Your Production Stage — Prototype or low volume? Choose laser cutting. High volume? Consider stamping after design freeze.
- Determine Required Torque & RPM — Higher torque needs more stack length or larger diameter. High RPM demands thinner laminations and low-loss material.
- Select Slot/Pole Combination — Common drone motors use 12S/14P or 9S/6P. This affects cogging torque, winding factor, and efficiency.
- Choose Lamination Thickness — For high-frequency operation (e.g., 400Hz+), use 0.20 mm laminations to reduce eddy current losses.
- Optimize Laser Parameters — Proper power, speed, and assist gas minimize burrs and heat-affected zone, preserving magnetic properties.
- Decide on Insulation & Coating — Epoxy powder coating is recommended for moisture, vibration, and chemical resistance.
- Plan for Stacking — Laser cut laminations can be interlocked, bonded, welded, or clamped, depending on your assembly method.
- Request Samples & Test — Reenives provides free samples for qualified projects. Test core loss, temperature rise, and mechanical fit.
FAQ — Laser Cut Stator Lamination Parameters
Q1: What are the advantages of laser cutting over stamping for stator laminations?
A: Laser cutting requires no hard tooling, so there is no tooling cost and lead times are much shorter — typically 3–7 days versus 15–25 days for a new stamping die. It also allows rapid design changes: you can modify the CAD file and re-cut immediately. Stamping becomes more economical at high volumes, where the tooling cost is amortized across many parts.

Q2: Does laser cutting affect the magnetic properties of stator laminations?
A: Laser cutting creates a small heat-affected zone (HAZ) along the cut edge, which can slightly increase local core loss. With optimized laser parameters (power, speed, assist gas), the HAZ is minimized. For most UAV motor designs, the impact is negligible. If magnetic performance is critical, we can recommend alternative cutting methods or post-processing.

Q3: What cutting tolerance can you achieve with laser cut stator laminations?
A: Our laser cutting process typically achieves tolerances of ±0.05 mm to ±0.10 mm, depending on material thickness and feature geometry. Burr height is controlled to ≤ 0.03 mm with optimized parameters. Tighter tolerances may be achievable for specific features — please consult our engineering team.

Q4: What lamination thickness do you recommend for high-RPM UAV motors?
A: For high-RPM UAV motors (above 10,000 RPM), we recommend 0.20 mm or 0.25 mm silicon steel laminations. Thinner laminations significantly reduce eddy current losses, which helps keep the motor cool and improves efficiency. For lower RPM applications, 0.35 mm or 0.50 mm can be more cost-effective.

Q5: Can you transition my laser cut design to stamping for mass production?
A: Yes. Once your design is validated with laser cut prototypes, we can develop a stamping die for high-volume production. This hybrid approach lets you iterate quickly with laser cutting, then reduce unit cost with stamping once the design is frozen. We support private mould development and can handle the transition seamlessly.

Q6: What is the minimum order quantity (MOQ) for laser cut stator laminations?
A: Laser cutting is well-suited to low volumes and prototyping, so our MOQ is flexible — we support sample orders and small batches. For custom private mould projects, MOQ depends on the tooling and design complexity. Please contact us with your requirements for a precise quote.
