SuperLight Series Motors

The SuperLight (SL) Series represents VectorTechnics' dedicated line of low-profile, efficiency-first brushless motors. They are engineered specifically for long-endurance vertical takeoff and landing (VTOL) UAVs, commercial mapping platforms, and professional surveillance aircraft where weight minimization and aerodynamic efficiency are the absolute priorities.

Design Philosophy​

Weight Saved → Battery Capacity Added → Extended Flight Time

By utilizing lightweight materials, optimized hollow shafts, and low-profile stator assemblies, SL motors deliver maximum torque-to-weight ratios without sacrificing structural durability.

Core Engineering Features​

  • Ultralight Architecture: Low-profile shell structures minimize raw frame weight.
  • High Pole Configurations: Enhanced magnetic leverage for high torque density.
  • Premium Materials: High-temp copper wiring, Japanese EZO ball bearings, and N48SH/N52SH curved magnets.
  • Precision Balanced: High-standard balancing tolerances to minimize vibrations and sensor distortion.

SuperLight Model Lineup​

The SL series spans several stator diameters to cover small mapping drones up to large, high-efficiency commercial quadcopters.

Small-Mid Cruising Class​

Optimized for lightweight mapping UAVs, inspection drones, and 4S–8S platforms.

High-Efficiency Lift Class​

Built for large multi-rotor systems where maximum aerodynamic efficiency and hover endurance are crucial.

Performance Characteristics​

SL Series motors are optimized for hovering and forward flight cruise efficiency:

  • Higher g/W (grams of thrust per watt) at hover throttles (typically 40%–50%).
  • Low cogging torque for smooth prop start-up and control stability.
  • Excellent thermal performance at steady-state cruising power.

SuperLight motors are ideal for:

  • Long-endurance security and surveillance drones.
  • Photogrammetry and mapping quadcopters.
  • Multi-rotor VTOL cruise systems (puller/pusher motors).
  • Inspections requiring minimum electrical noise.

Operational Guidelines​

For optimal service life and performance:

  • Limit sustained throttle to maximum continuous current ratings.
  • Match with high-efficiency carbon fiber propellers.
  • Ensure the motor mounting base is clean and flat to avoid internal strain.
  • Regularly inspect bell rotation and clean of any metal debris.
