⚙️ What is 100 KV Brushless Motor Stator Core?

The 100 KV brushless motor stator core is the stationary electromagnetic component that determines torque density, thermal dissipation, and overall motor KV consistency. In high-RPM drone motors, a precision-laminated stator core made of non-grain oriented silicon steel directly impacts eddy current losses, efficiency, and power-to-weight ratio. For 100 KV rating — commonly used in larger UAV propulsion, FPV racing, and industrial servo drives — stator core geometry (slot/pole combination, stacking factor, insulation coating) dictates reliable high-speed operation. Reenives provides ready-to-assemble stator cores with epoxy powder insulation, high-permeability materials (0.2mm/0.35mm lamination), tailored for 100 KV brushless motor OEMs.

🔧 Stator Core Classification — Tailored for 100 KV Variants

Reenives manufactures stator cores optimized for both airborne drone motors and industrial brushless motors. Classification based on:

Lamination material grade: 35CS440, 20WTG1300, 0.2mm ultra-thin Si-steel for high frequency (up to 100 KV suitable for 10k-30k RPM).
Coating technology: Epoxy powder coating (edge insulation) or oxide layer – reduces inter-lamination short circuits.
Outer diameter range: 22mm to 120mm (for 100 KV typical sizes: 30XX, 40XX, 62XX series stator cores).
Slot design: Open slot / semi-closed slot for automatic winding machines — copper fill >90% achievable.

✅ For 100 KV brushless drone motors, Reenives recommends ultra-thin 0.2mm laminations + vacuum heat treatment → reduces hysteresis loss by 18% compared to conventional 0.35mm stacks. Our classification system also supports pilot samples (10–50 pcs) and high-volume bulk orders (10k+ units).

🚁 Applications — Beyond Drones & General Brushless Motors

While optimized for UAVs, our 100 KV brushless motor stator cores empower:

Heavy-lift drones & agricultural spraying UAVs – high torque consistency at lower KV yields longer flight time.
Electric vertical take-off and landing (eVTOL) prototypes – demanding low cogging torque & minimal vibration.
FPV racing motors – core response to rapid throttle changes, 100 KV variant for 6S–8S LiPo.
Industrial servo motors, AGV drive motors, and e-scooter hubs – custom bore diameters and mounting holes.

📐 How to Select the Optimal 100 KV Brushless Motor Stator Core: 5-Step Guide

Step 1: Determine electrical frequency & RPM range. 100 KV = 100 RPM per volt; for 24V systems, ~2400 RPM unloaded. Confirm lamination thickness (0.2mm recommended above 600Hz).

Step 2: Calculate required torque density. For UAV propeller loading, slot/pole combination (12N14P vs 18N20P) alters torque ripple. Reenives engineering team can simulate with Maxwell.

Step 3: Choose insulation coating. Epoxy powder coating ensures corrosion resistance and inter-lamination isolation – mandatory for wet/dusty drone environment.

Step 4: Core dimension & tolerance validation. Share your housing ID and winding technique (needle winder/pin insertion). We provide 3D drawings within 48h.

Step 5: Prototype & verification. Reenives offers free pre-production samples (shipping costs may apply) and provides BH curve test report, Back EMF consistency test.

❓ FAQ — 100 KV Stator Core Engineering Insights

1. What lamination material minimizes eddy current losses for a 100 KV drone motor running at 24,000 RPM?

We recommend 0.20mm non-grain oriented silicon steel (e.g., 20WTG1300) with epoxy coating. It reduces eddy current loss by ~35% compared to 0.35mm standard laminations. This data is based on Reenives' IEC 60404-2 loss testing. (Source: Reenives engineering parameter table)

2. What is the maximum stacking thickness for 100 KV stator cores without compromising magnetic saturation?

For outer diameter 40–62mm, stacking up to 35mm is feasible with saturation flux density >1.65T. Beyond this, we suggest increasing diameter to avoid saturation at peak current. Source: Reenives magnetic simulation library & sample validation. (Source: Technical spec table above)

3. Can Reenives support private mould development for unique slot geometries (e.g., tapered slots for higher copper fill)?

Yes, as a leading stator core supplier we support private moulds; 100% tailored to your winding pattern. Minimum order for custom tooling starts at 2000 units. Contact us for CAD review. (Source: Company OEM capability statement)

4. What insulation system do you use to prevent inter-laminar shorts under high humidity drone environment?

We utilize high-edge epoxy powder coating (C5 insulation class) applied via electrostatic spraying, withstand 1500VAC for 60 seconds without leakage, salt spray test passed >96h. (Source: Coating process classification & IEC 60034-18)

5. What is the typical lead time for bulk orders (10,000 pcs) of 100 KV brushless motor stator cores?

For bulk orders (after sample approval), lead time is 20–25 days. Express tooling available for urgent projects. Reenives holds 3 production bases, capacity >500k stator cores/month. (Source: Production & logistics data)
