Motor Lamination Manufacturers: How to Choose a Renowned Drone Stator Core Supplier

⚠️ Inconsistent lamination quality, high core loss, and supply chain delays? For drone motor engineers and procurement managers, selecting the right motor lamination manufacturer directly impacts thrust efficiency, thermal performance, and production scalability. Inferior stamping leads to shorted laminations, vibration, and field failures.

Reenives has earned its reputation as one of the most renowned drone motor lamination manufacturers in China. With over 100 R&D patents, imported stamping lines, and a dedicated focus on 0.20mm ultra-thin stator cores, we provide burr-free laminations, epoxy insulation, and custom tooling for UAV/FPV and general BLDC motors. This guide helps engineers evaluate lamination manufacturers based on verifiable technical parameters and real-world production capabilities.

📌 What Are Motor Laminations (Stator Cores)?

Motor laminations are thin sheets of electrical steel that are stamped and stacked to form the stator core of a BLDC motor. The lamination process reduces eddy current losses by insulating individual layers. For drone motors operating at high frequencies (20-80kHz), high-quality laminations are non-negotiable. Reenives manufactures laminations using progressive dies and high-speed presses (imported from Japan/Germany), achieving consistent thickness (<0.005mm tolerance) and minimal burr height (≤0.012mm). Our epoxy powder coating provides superior insulation and thermal stability up to 180°C.

🏗️ Classification of Motor Lamination Cores for Drones

Based on construction and manufacturing process, Reenives supplies three main types:

• Segmented laminations – Individual teeth stamped separately and assembled; ideal for high pole-count drone motors (12N14P, 24N28P) to simplify winding.
• Integrated ring laminations – Single-piece continuous stack for maximum structural rigidity; used in heavy-lift UAVs and industrial BLDC motors.
• Custom slot geometries – Parallel slots, trapezoidal slots, skewed slots for noise reduction. Reenives supports private mould development for any custom design.

Our classification also includes material grades: 0.20mm ultra-thin (for FPV/high RPM), 0.27mm (balanced performance), and 0.35mm (cost-effective for low-frequency apps).
