Description

The RS0802 KV20000 motor is a core component for high-performance 1S micro and whoop-class drones. Its ultra-high KV rating translates to rapid throttle response and high rotational speeds on single-cell LiPo power, making it ideal for acrobatic freestyle and tight racing circuits where instant torque is critical.

Constructed with a precision 9N12P (9 stator teeth, 12 magnet poles) configuration, the motor balances efficiency with power output, minimizing electrical losses for extended flight times. The lightweight 2-gram design reduces overall system mass, allowing for more dynamic maneuvers and improved battery efficiency in constrained airframes.

Key Features

  • 1S-Optimized High KV: 20000KV rating delivers maximum RPM per volt for explosive acceleration on 1S LiPo packs.
  • Micro-Stator Design: 8mm stator diameter paired with a 1.5mm shaft provides a compact yet robust magnetic circuit.
  • Precision Magnetic Configuration: 9N12P design ensures smooth rotation, reduced cogging torque, and efficient power conversion.
  • Lightweight Durability: High-grade materials and construction achieve a 2g weight without sacrificing mechanical integrity.
  • Direct-Connect Wiring: Includes 30mm leads terminated with industry-standard JST 1.25mm connectors for plug-and-play compatibility with most micro AIO flight controllers.
  • Thermal Management: Efficient design and material selection help dissipate heat, maintaining performance during sustained high-throttle runs.

Applications

  • Primary propulsion for 1S-powered micro FPV whoop drones (e.g., Mobula7, Mobula7 HD).
  • Upgrade motor for TinyWhoop-class racers requiring higher thrust and throttle response.
  • Lightweight freestyle builds in 65mm to 75mm ducted frame categories.
  • Indoor and backyard micro drones where minimal weight and high agility are paramount.

Frequently Asked Questions

What battery voltage is the RS0802 20000KV motor designed for?

The RS0802 20000KV motor is specifically optimized for 1S LiPo battery systems. Its high KV rating is intended to produce maximum rotational speed (RPM) from the nominal 3.7V of a single-cell battery, making it unsuitable for higher voltage (2S+) setups which would likely cause overheating and failure.

What is the shaft diameter and what size propellers does it fit?

This motor features a 1.5mm shaft diameter. It is designed to press-fit standard 1.5mm bore micro drone propellers, such as 31mm or 40mm tri-blade props commonly used on 65mm-75mm whoop frames. Always ensure the propeller bore matches the shaft size to prevent slippage or imbalance.

Is this motor compatible with the Mobula7 drone?

Yes, the HappyModel RS0802 20000KV motor is a direct physical and electrical replacement for the motors in the 1S versions of the Mobula7 and Mobula7 HD drones. It uses the same JST 1.25mm connector and mounting pattern, allowing for a straightforward swap to upgrade thrust or replace a damaged motor.
