Description

The HappyModel SE0702 KV23000 brushless motor is engineered for the demanding power and weight requirements of modern micro FPV drones. Its compact 7x2mm stator and 9N12P magnetic configuration deliver efficient, high-speed rotation directly from a single-cell LiPo battery, making it a core component for high-performance tiny whoops.

Constructed with a focus on minimal mass, the motor’s 1.5g weight significantly reduces overall drone inertia, enabling rapid throttle response and precise acrobatic control. The 1mm hardened steel shaft ensures reliable coupling with micro propellers, maintaining integrity during high-RPM operation and minor impacts typical in indoor or tight-space flying.

Key Features

  • Ultra-Micro Stator Design: 7mm diameter by 2mm length stator provides a dense magnetic field in a minimal footprint, maximizing torque output for its size.
  • Precision 1mm Shaft: Hardened steel shaft ensures precise propeller alignment and durability for high-RPM micro applications.
  • Optimized 9N12P Configuration: This pole count balances smooth cogging torque with efficient power delivery, ideal for the high KV and fast electronic timing required by 1S systems.
  • Lightweight Airframe Integration: At just 1.5 grams, it allows builders to achieve sub-20g AUW (All-Up Weight) targets for competitive tiny whoop racing.
  • Direct 1S LiPo Compatibility: Engineered to operate efficiently at nominal 3.7V, eliminating the need for voltage regulation and simplifying power system design.

Applications

  • Ultra-lightweight 65mm to 75mm tiny whoop FPV drones for indoor racing and freestyle.
  • Micro brushless conversion kits for lightweight ducted cinewhoop platforms.
  • High-performance 1S micro freestyle quadcopters under 30g AUW.
  • Experimental nano and pico-class drone builds requiring extreme power-to-weight ratios.
  • DIY micro UAVs for swarm robotics or educational platforms where minimal weight is critical.

Frequently Asked Questions

What is the compatible propeller size for the SE0702 motor?

The SE0702 motor is designed for 31mm propellers, specifically those with a 0.8mm or 1mm hub hole. It is directly compatible with popular models like the Gemfan 31mm and HQProp 31mm tri-blade or bi-blade propellers commonly used in 65mm-75mm tiny whoop builds.

Can this motor run on 2S LiPo batteries?

No, the SE0702 motor is strictly designed for 1S LiPo operation (nominal 3.7V). Applying 2S voltage (7.4V) would significantly exceed its design limits, leading to immediate overheating, demagnetization of the rotor, and almost certain motor failure. Always pair it with a 1S LiPo and a compatible 1S-rated ESC.

What is the recommended ESC for the HappyModel SE0702?

You need a brushless ESC specifically rated for 1S voltage and capable of driving high-KV micro motors. Look for 1-2S AIO (All-In-One) flight controllers with integrated ESCs or dedicated 1S micro ESCs that support BLHeli_S or BLHeli_32 firmware. Ensure the ESC's current rating (typically 5A-12A) is sufficient for the motor's peak draw.
