What Is a 2807 Drone Motor Stator Lamination?

A 2807 drone motor stator lamination is a single thin sheet of electrical steel — typically silicon steel — stamped into a specific slotted ring shape and stacked with many identical sheets to form the stationary stator core of a brushless outrunner motor sized "2807." In the drone motor naming convention, the four-digit code describes the stator core dimensions:

• First two digits "28" = stator outer diameter ≈ 28 mm
• Last two digits "07" = stator stack height ≈ 7 mm

So a 2807 stator lamination is a 28 mm outer diameter slotted lamination, and a complete 2807 stator core is built from many of these laminations stacked to a 7 mm height. Each lamination is individually coated with a thin insulation layer to limit eddy currents between layers. The lamination profile itself defines the slot count (typically 12 slots), the tooth width, the yoke width, and the inner bore (typically 13 mm or 14 mm).

The 2807 stator lamination is the fundamental building block of one of the most popular motor sizes in the FPV and long-range drone world. It powers 6–7 inch propeller setups used in freestyle, cinematic, and long-range flight. Its 28 mm diameter and 7 mm stack height determine how much copper the motor can hold, how much torque it can produce, and how well it dissipates heat during aggressive flight.

Put simply: the 2807 stator lamination is the "power-producing frame" of the motor, and the quality of each individual lamination — its material grade, thickness, edge quality, and coating — determines the motor's efficiency and thermal performance.

Types of 2807 Stator Laminations

2807 stator laminations come in several configurations, each suited to different motor designs and performance requirements. Reenives manufactures the following types:

• 12N14P 2807 Laminations — The industry-standard slot/pole combination for 2807 motors. 12 slots, 14 poles. Delivers smooth torque delivery with low cogging — critical for freestyle and cinematic flight.
• 0.2 mm Silicon Steel Laminations — The industry standard for 2807 motors. Ultra-thin laminations reduce eddy current losses, which is essential at the high electrical frequencies FPV motors operate at. Used by Lumenier, Hobbywing, GEPRC, RCinpower, and EMAX.
• 0.15 mm Ultra-Thin Laminations — For the most demanding high-RPM applications, some FPV motors use 0.15 mm silicon steel to further reduce eddy current losses.
• Interlocked Laminations — Laminations with integral dimples or dovetails that lock together under pressure. Cost-effective for high volume. Standard in most 2807 motors.
• Bonded Laminations — Laminations bonded with adhesive instead of interlocking, reducing eddy current losses and vibration.
• Epoxy-Coated Laminations — Powder-coated for enhanced insulation, corrosion resistance, and wire adhesion. H-class 180°C electrostatic coating is standard for FPV stator applications.
• Segmented Laminations — Individual teeth stamped separately and assembled, achieving higher slot fill factors.
• Custom 2807 Laminations — Private mould development for unique bore diameters (13 mm or 14 mm), slot shapes, and stack heights (2807, 2809, 2810, 2812, etc.).

Whether you need a standard 2807 stator lamination for a 6-inch freestyle motor or a custom stack height for a specialized long-range build, Reenives can deliver.

Applications & Why 2807 Matters

The 2807 stator lamination is specifically engineered for the most demanding mid-size FPV and long-range applications. Here is where the 2807 makes a measurable difference:

• 6–7 Inch Freestyle FPV Drones — The 2807's 28×7 mm iron package provides the torque needed to swing 6–7 inch props with authority. The 0.2 mm laminations keep core loss low at the high electrical frequencies these motors run at, which means more power delivered to the prop and less wasted as heat.
• Long-Range FPV Cruisers — Higher torque at moderate KV means efficient cruise flight with minimal throttle. The low-loss silicon steel directly translates to longer flight time per battery pack — critical for long-range missions.
• Cinematic FPV Drones — The 2807 stator lamination's 12N14P configuration delivers smooth torque with low cogging. Combined with dynamic balancing in the finished motor, this produces jello-free footage — essential for professional cinematography.
• 7–8 Inch Prop Setups — The 2807's larger iron package (compared to 2207) supports the higher torque requirements of 7–8 inch props, making it suitable for long-range and heavy-lift FPV builds.
• Fixed-Wing UAV Motors — The 28 series stator platform (including 2807) is used in fixed-wing long-range UAV motors, where efficiency and thermal stability are paramount.

Reenives 2807 stator laminations are used across a wide range of drone and brushless motor applications:

• 6–7 Inch Freestyle FPV Drones — High-performance acro and freestyle platforms.
• Long-Range FPV Cruisers — Efficient endurance platforms.
• Cinematic FPV Drones — Professional aerial cinematography.
• Fixed-Wing Long-Range UAVs — Efficient cruise platforms.
• Industrial Inspection UAVs — High-torque motors for stable hover and sensor payloads.
• eVTOL & UAV Propulsion — Custom high-power stators for next-generation air mobility.
• General BLDC Motors — Fans, pumps, robotics, and industrial actuators.

Reenives 2807 stator laminations power 6–7 inch FPV freestyle drones, long-range cruisers, and fixed-wing UAVs worldwide.

How to Select the Right 2807 Stator Lamination

Choosing the correct 2807 stator lamination for your motor involves several engineering decisions. Follow these steps:

1. Confirm Stator Dimensions — Verify the required outer diameter (28 mm) and stack height (7 mm standard). Custom stack heights such as 9 mm (2809), 10 mm (2810), or 12 mm (2812) are available for specialized builds.
2. Select Inner Bore Diameter — The 2807 stator is available with either a 13 mm or 14 mm inner bore. Confirm which matches your rotor and shaft design.
3. Choose Lamination Thickness — 0.2 mm is the standard for 2807 motors. For the most demanding high-RPM applications, 0.15 mm laminations can further reduce eddy current losses.
4. Select Lamination Material — 20JNEH1200 and Kawasaki silicon steel are the industry benchmarks for 2807 stator cores. These low-loss grades minimize core loss at high frequency.
5. Decide on Insulation Coating — Epoxy powder coating with H-class 180°C rating and electrostatic application is standard for FPV stator applications. This improves corrosion resistance and wire adhesion.
6. Consider Assembly Method — Interlocked laminations are the standard for 2807 motors. Bonded laminations reduce vibration and eddy current loss but cost more.
7. Verify Tolerances & Burr Height — Tight tolerances (±0.05 mm) and minimal burrs (≤ 0.03 mm) ensure proper stacking and reduce vibration.
8. Request Samples & Test — Reenives provides free samples for qualified projects. Test core loss, temperature rise, and mechanical fit before committing to production.
