1. What Defines a Large Brushless Motor Stator Lamination?
For large brushless motors, stator laminations are the magnetic core building blocks that dictate torque density, efficiency, and thermal performance. Typically exceeding 200mm outer diameter, each lamination is punched from non-oriented silicon steel (0.27mm–0.35mm) to minimize eddy current losses while ensuring structural rigidity under high magnetic flux. Reenives’ advanced progressive dies guarantee burr-free edges and ±0.02mm dimensional accuracy for seamless stacking.

3. Technical Specifications (IEC & Reenives Lab Data)
- Outer diameter range: 120mm – 550mm (custom tooling available)
- Stack height tolerance: ±0.05mm (for 20–180mm stack length)
- Core loss (P1.5/400): ≤ 11.6 W/kg for 27GP120 grade → 32% reduction vs. standard 50A800
- Slot fill factor potential: up to 94% with optimized tooth geometry
- Inter-laminar resistance: >80 MΩ after epoxy coating (test @500V)
- Burr height: ≤0.03mm (meets IEC 60335-1)
Data source: Reenives in-house dyno validation & third-party SGS report #CN24/0127, conforms to IEC 60404-2. Batch core loss tested weekly.
4. Critical Applications for Large Brushless Motor Laminations
5. Engineering Selection Guide: Large Brushless Motor Laminations
- Determine OD, ID, and stack length – based on torque & packaging constraints.
- Select lamination steel grade & thickness: 0.35mm for <500Hz, 0.27mm for 500–1000Hz, 0.20mm for >1kHz.
- Insulation type: epoxy coating for high humidity/dust environments, varnish for cost-sensitive designs.
- Stacking method: interlocking for mechanical integrity, bonded core for minimum eddy losses.
- Rapid prototyping: Reenives supplies sample laminations within 10 days, complete core loss report included.
