Description

The 8520 Magnetic Micro Coreless Motor is designed for micro-class FPV drones, quadcopters, and miniature aircraft requiring a compact and lightweight propulsion solution. Its coreless construction eliminates the traditional iron core, helping reduce rotational inertia and enabling faster response characteristics compared to conventional brushed motors.

Operating directly from a 1S LiPo battery, the motor delivers high-speed performance while maintaining a lightweight design suitable for small drone frames. The compact 8.5 × 20mm form factor makes it a popular choice for drone builders looking for replacement or upgrade motors for micro quadcopters.

The motor features low-noise operation, efficient power delivery, and compatibility with common push-fit propellers used in micro drone applications.

Features:

  • Coreless motor design reduces rotational inertia
  • Compact and lightweight construction
  • High RPM output for micro drone applications
  • Compatible with 1S LiPo batteries
  • Low-noise operation
  • Fast acceleration and response characteristics
  • Suitable for micro quadcopters and FPV drones
  • Compatible with push-fit propellers
  • Available in CW and CCW rotation variants

Note:

  • Reversing wire polarity changes the motor rotation direction.
  • Wire colours and rotation configuration may vary depending on batch.
  • Confirm motor rotation direction before installation.
