Reduce iron loss by up to 28%, increase continuous torque by 15%. Trusted China supplier with global shipping.

🔩 What is a 2830 Brushless Motor Stator Lamination? (Definition)

The 2830 brushless motor stator lamination refers to a stator core with outer diameter 28mm (2830 class: 28mm stator OD x 30mm rotor OD). It consists of stacked ultra-thin non-oriented silicon steel sheets, typically with 12 slots and 14 poles (12N14P) or 9N12P configurations. This size class is widely used in medium-lift drones, small e-scooters, electric skateboards, and robotics actuators. Lamination quality directly impacts eddy current loss, cogging torque, and overall motor efficiency at varying RPMs.

⚙️ Engineering Selection Steps for 2830 Stator Lamination

Define motor KV & voltage: 800-1400KV for 4S-6S drone systems, lower KV for e-scooters.
Select stack height: 15-20mm for lightweight drones, 25-30mm for high-torque industrial drives.
Choose lamination thickness: 0.20mm for high-frequency >25,000 RPM, 0.27mm for cost-optimized.
Specify coating type: Epoxy edge coating mandatory for outdoor/moisture-prone applications.
Review BH curve & core loss map: Reenives provides per-batch magnetic characterization.
Validate dimensional tolerances: ID concentricity ≤0.02mm, flatness ≤0.02mm for consistent air gap.

❓ FAQ – Critical Stator Lamination Pain Points for 2830 Motors

1. What lamination thickness minimizes eddy current loss for 2830 motors at 25,000-35,000 RPM?

For 2830 motors operating above 25,000 RPM with PWM frequencies 20-28kHz, 0.20mm (20PN120) ultra-thin silicon steel is optimal. It reduces high-frequency eddy current loss by up to 35% compared to 0.27mm laminations, directly improving thrust efficiency for racing drones.

2. How does epoxy edge coating affect 2830 stator thermal performance?

Epoxy powder coating (45-70μm thickness) provides inter-lamination insulation while improving heat dissipation (thermal conductivity 0.85-0.90 W/m·K). In continuous drone hover tests, epoxy-coated stators run 10-14°C cooler than uncoated laminations, extending magnet and bearing life.

3. What is the typical slot fill factor for a 2830 stator lamination with Reenives design?

Reenives optimized tooth geometry allows slot fill factor up to 89-92% (using automated winding machines). Higher fill factor increases copper cross-section, reducing I²R losses and improving torque density for e-scooter hub motors.

4. Can Reenives supply stator laminations with private mould for non-standard 2830 variants?

Yes, we support private mould development for any 28mm class stator (custom slot shape, tooth profile, mounting holes). Minimum sample order: 50 pcs. Lead time for new tooling: 18-22 days. Over 350+ custom BLDC lamination moulds delivered globally.

5. What core loss value should I expect at 1.2T / 500Hz for a standard 2830 stator (0.27mm material)?

Using Reenives 0.27mm grade 27PN140, typical iron loss ≤16.5 W/kg @ 1.2T / 500Hz. For premium 0.20mm grade, loss ≤11.8 W/kg. Each shipment includes Epstein test certification with batch traceability and BH curve.
