1. What are Brushless Motor Stator Laminations? (Core Definition)
Stator laminations are the magnetic circuit core of a brushless motor, consisting of thin insulated electrical steel sheets stacked together. They minimize eddy current losses, channel magnetic flux, and directly determine torque density, efficiency, and thermal performance. For UAV FPV drone propulsion systems, ultra-precision laminations (0.2mm~0.35mm thickness) with high permeability ensure responsive throttle and prolonged flight endurance.

2. Classification by Material & Coating Technology
Reenives manufactures stator laminations optimized for both high-speed UAV motors and heavy-duty industrial brushless motors.
| Type | Material Grade | Thickness (mm) | Coating | Application Scenario |
|---|---|---|---|---|
| Ultra-thin High Frequency | 35PN210 / 20JNEH1200 | 0.20 – 0.27 | Epoxy powder insulation (green/blue) | High-speed UAV FPV, eVTOL, drone racing |
| High Efficiency Industrial | 50WW470 / 35WW270 | 0.35 – 0.50 | Phosphate + epoxy coating | Servo motors, e-scooters, AGV, power tools |
| Custom Prototype | Non-oriented silicon steel (M470-50A) | 0.30 / 0.35 / 0.50 | Customizable anti-rust coating | R&D projects, small batch high-torque motors |
Epoxy powder coating from imported production lines ensures superior inter-laminar resistance, reducing parasitic losses by up to 18% compared to conventional varnish.
3. Technical Parameters & Test Source (Independent Lab Data)
Based on third-party validation (CSA Group Test Report #RV-2240, 2024) and Reenives internal QA, our stator laminations achieve the following benchmarks:
| Parameter | Typical Value | Test Condition |
|---|---|---|
| Core loss (W/kg) @ 1.0T, 400Hz | ≤ 9.5 W/kg | Epstein Frame, 25°C |
| Saturation flux density (Bs) | 1.68 – 1.72 T | DC BH looper |
| Stacking factor | ≥ 97.5% | Hydraulic press, 300 MPa |
| Interlaminar resistance (Ω·cm²) | > 150 | Franklin tester |
| Operating temperature range | -40°C ~ 180°C | Thermal chamber cycling |

5. Engineering Selection: 5-Step Process for Stator Laminations
To match your brushless motor performance goals, follow these industry-tested steps:
- Define operating frequency & flux density: for UAV motors (200-600Hz), use ≤0.27mm laminations.
- Select geometry (outer/inner diameter, slot number): 9N12P, 12N14P patterns available.
- Choose coating insulation: epoxy powder for high humidity / dust environments (IP rating).
- Check stacking method: welding, interlocking or bonding depending on torque ripple sensitivity.
- Request engineering samples & core loss report: Reenives provides sample-making within 10 working days.
🎯 Pro tip: Our in-house private mould development allows any custom slot shape, reducing prototyping cost by up to 40%.
