1. What is a Stator in an Electric Motor? (Engineering Definition)

The stator in an electric motor is the stationary electromagnetic component consisting of laminated silicon steel stacks with copper windings. It generates a rotating magnetic field that interacts with the rotor to produce mechanical torque. In brushless DC (BLDC) motors — particularly for drones and robotics — the stator directly determines key performance metrics: torque density, efficiency, heat dissipation, and power-to-weight ratio. A high-quality stator core minimizes eddy current and hysteresis losses, enabling longer flight times and precise servo control.

Reenives precision-laminated stator core — compatible with 9-slot, 12-slot, and custom configurations for UAV and industrial motors.

2. Classification of Stator Cores for Electric Motors

Reenives manufactures a comprehensive range of stator cores tailored to electric motor applications, classified by construction and material process:

• 🔩 Segmented Stator Core: Individual tooth segments assembled into a ring — ideal for concentrated windings and automated production (common in drone motors).
• ⚙️ Full-Ring (One-Piece) Stator: Single stamped lamination stack for higher mechanical rigidity and lower assembly cost — best for high-volume BLDC fans and pumps.
• 🛡️ Epoxy Powder-Coated Stator: Pre-insulated stator core eliminates need for separate slot liners — dielectric strength ≥ 2.5kV, Class H (180°C).
• 🧲 High-Frequency Stator (0.20mm lam): Ultra-thin laminations for drone motors operating above 30,000 RPM — reduces eddy current loss by 40%.

Compared to generic stator cores, Reenives’ precision-stamped stator in electric motor reduces total iron loss by up to 28% and improves thermal conductivity by 35% — verified on 2807 drone motors at 80% throttle.

4. Applications: Stator in Electric Motor for Drone, Robotics & BLDC

Reenives stator cores serve as the critical component across diverse electric motor applications, with specialized optimization for UAV propulsion and robotic actuation:

• ✈️ Drone Motors (FPV, Agricultural, eVTOL): High power density stators with 12N14P topology for smooth torque and extended flight endurance.
• 🤖 Robot Servo & Joint Motors: Low cogging torque and precise back-EMF waveform for collaborative robots (cobots) and medical robotics.
• 🛴 E-Scooter / E-Bike Hub Motors: Robust full-ring stators for direct-drive torque.
• 🏭 Industrial BLDC Pumps, Compressors & Fans: High-efficiency stators for continuous duty cycles.
• 🚗 Automotive Auxiliary Motors (EPS, Cooling): Reliable stator cores with epoxy coating for harsh environments.

5. Step-by-Step Stator Selection Guide for Electric Motor Engineers

Step 1: Define motor power requirements and operating speed (RPM) — high-speed drone motors require 0.20mm laminations.
Step 2: Select slot/pole combination (e.g., 9N12P for cost-sensitive, 12N14P for torque density).
Step 3: Specify stator outer diameter and stack height (e.g., 2806 drone → 28mm OD, 6mm stack).
Step 4: Choose insulation method: epoxy pre-coating (best for moisture/dust) or slot liner paper.
Step 5: Request tolerance analysis, sample approval, and private mould development — Reenives provides full customization.

👉 Pro Tip: For maximum efficiency, pair a high-grade silicon steel stator (M330-35A) with an optimized winding pattern to achieve fill factor > 88%.
