Description

The HappyModel SE0702 brushless motor is engineered for the demanding needs of modern micro FPV racing and freestyle. Its 28000KV rating, derived from a 7mm stator diameter and 2mm stator length, generates significant rotational speed, translating to rapid throttle response and high top-end thrust for 1S-powered drones. The 9N12P (9 stator slots, 12 magnet poles) configuration enhances torque smoothness and reduces cogging, contributing to stable flight characteristics and efficient battery consumption.

Constructed with a focus on minimal mass, the motor’s 1.46-gram weight is critical for ultra-lightweight builds where every gram impacts flight time and maneuverability. The integrated 1mm hardened steel shaft provides the necessary durability for direct propeller mounting, resisting bending under high-RPM loads. This motor is a core component for pilots seeking to maximize the performance of their micro whoop or toothpick-style quadcopters within the strict constraints of 1S power systems.

Key Features

  • Ultra-High 28000KV Rating: Delivers exceptional RPM per volt, ideal for generating high thrust on 1S voltage.
  • Micro Stator Design: 7x2mm (0702) stator dimensions provide an optimized balance of power and compact size.
  • Precision 9N12P Configuration: Ensures smooth rotation, reduced vibration, and improved efficiency for longer flight times.
  • Hardened 1mm Steel Shaft: Offers high torsional strength and reliable mounting for micro propellers.
  • Minimalist 1.46g Weight: Critical for achieving the highest possible power-to-weight ratio in sub-20g drone builds.
  • 1S LiPo Optimization: Engineered electrical characteristics are tuned for the discharge curve of single-cell lithium polymer batteries.

Applications

  • High-performance 65mm to 75mm Tiny Whoop FPV drones for indoor/outdoor racing.
  • Ultra-lightweight 1S-powered micro toothpick and freestyle quadcopters.
  • Compact cinewhoop builds requiring aggressive throttle response for dynamic footage.
  • DIY micro drone projects where minimizing weight is paramount for flight duration and agility.

Frequently Asked Questions

What is the compatible voltage range for the HappyModel SE0702 28000KV motor?

The SE0702 motor is specifically optimized for 1S LiPo battery systems, with a nominal voltage of 3.7V. It is designed to operate within the standard 1S voltage range, typically from 3.2V (low voltage cutoff) to 4.2V (fully charged). Using it with higher voltage (e.g., 2S) will likely cause excessive current draw, overheating, and premature failure.

What size propellers and mounting pattern does this motor use?

This motor features a 1.0mm shaft diameter, which is standard for micro brushed and brushless motor propellers. It is compatible with push-on or press-fit propellers designed for 1mm shafts, commonly used in 31mm to 40mm diameters for tiny whoops. The mounting pattern typically uses M1.4 or M1.6 screws on a 6mm x 6mm or 7mm x 7mm hole pattern, standard for many micro drone frames.

Is this motor suitable for Betaflight and EmuFlight configurations?

Yes, the SE0702 is fully compatible with Betaflight, EmuFlight, and other standard flight controller firmware. As a brushless motor, it requires connection to a compatible micro brushless ESC (Electronic Speed Controller) that supports DShot or PWM protocols. Ensure your ESC firmware (e.g., BLHeli_S) is configured for the correct motor direction and timing for optimal performance.
