Drone motor designers and industrial buyers often struggle with 100W Brushless DC Motor efficiency drops due to inferior stator core materials — increased eddy current loss, unstable torque, and overheating. Reenives solves these pain points with precision-engineered stator cores, offering ultra-low core loss (≤2.8W/kg @50Hz), high slot fill factor, and epoxy powder coating for insulation reliability. As a specialized stator core manufacturer, we deliver solutions that boost motor power density by up to 22%.

🔧 100W Brushless DC Motor Stator Core: Definition & Core Role

The stator core of a 100W Brushless DC Motor consists of thin silicon steel laminations stacked together, forming the stationary magnetic circuit where electromagnetic torque is generated. For drone motors (UAV), lightweight and high saturation flux density are critical. Reenives stator cores use 0.2mm / 0.35mm non-grain oriented silicon steel with advanced stamping and vacuum annealing to minimize hysteresis loss, providing consistent performance for high-RPM applications.

📂 Classification of 100W BLDC Stator Cores (Drone & General Purpose)

Based on slot geometry, lamination shape and insulation coating, our stator cores are categorized as:

• 12S14P / 9N12P drone-optimized stators – high torque-to-weight ratio, used in racing drones & agricultural UAVs.
• 24-slot industrial BLDC stators – for CNC spindle, medical pumps, and robotics.
• Epoxy powder coated stators – superior insulation, moisture resistance, and thermal conductivity (standard for all Reenives 100W series).
• Custom stack heights from 8mm to 35mm to match various 100W power levels.

🔍 4-Step Selection Guide for 100W BLDC Stator Core (Engineer Focus)

To match optimal core to your motor design, follow this technical workflow:

1. Identify operating frequency & speed range: For 100W, typical range 3000–10000 rpm. High rpm requires thinner laminations (0.2mm) for reduced eddy currents.
2. Determine outer diameter & stack length: Based on torque constant (Kt) and available slot area. Reenives provides free finite element analysis (FEA).
3. Choose insulation coating thickness: Standard epoxy 0.05~0.1mm, suitable for drone/high humidity environments.
4. Request prototype samples: Evaluate core loss and mechanical fit. Reenives offers free sample evaluation for qualified OEMs.
