Description

The EX1404 motor series from HappyModel represents a focused engineering effort to maximize power-to-weight ratios for the micro drone segment. The KV2750 variant is specifically tuned to extract high thrust from 3S and 4S LiPo packs without excessive current draw, enabling longer flight times and cooler operating temperatures.

Its compact 17.8mm stator size and 9N12P magnetic configuration are designed for rapid acceleration and precise control, critical for acrobatic freestyle and tight racing circuits. The motor’s durable construction and balanced bell contribute to smooth, vibration-free operation, which is essential for clean FPV video feed quality.

Key Features

  • High-torque 9N12P stator design for instant throttle response and smooth power delivery.
  • Precision-balanced bell and high-grade bearings minimize vibration for stable flight.
  • Optimized magnetic circuit and winding pattern for high efficiency and low operating temperatures.
  • Durable anodized aluminum housing protects internal components from impacts and heat.
  • 1.5mm hardened steel shaft ensures reliable propeller mounting and resistance to bending.
  • Lightweight construction prioritizes performance-to-weight ratio for agile micro drone flight characteristics.

Applications

  • High-performance 2.5-inch to 3-inch toothpick FPV drones requiring a balance of power and efficiency.
  • Lightweight 3-inch micro long-range builds where low weight and efficient 4S operation are critical.
  • Acro-focused micro freestyle drones designed for aggressive maneuvers and quick recovery.
  • Compact CineWhoop platforms that benefit from the motor's responsive thrust and smooth control.

Frequently Asked Questions

What is the recommended propeller size for the EX1404 2750KV motor?

The EX1404 2750KV motor is optimally paired with 2.5-inch to 3-inch bi-blade or tri-blade propellers, such as the Gemfan 3018 or 4024. Using larger props may over-stress the motor on 4S, while smaller props may not utilize its full thrust potential. Always monitor motor temperature during initial flights.

Can I run this motor on a 2S LiPo battery?

While technically possible, the 2750KV rating is quite high for 2S operation, resulting in significantly reduced RPM and thrust. This motor is engineered and tuned for 3S and 4S LiPo batteries to achieve its intended performance envelope and efficiency.

What is the significance of the 9N12P configuration?

The 9N12P (9 stator poles, 12 magnet poles) configuration creates a high magnetic pole count, which results in smoother rotation, finer control resolution, and higher torque at lower RPMs compared to lower pole-count designs. This translates to precise throttle control and reliable performance in dynamic flight scenarios.

Is a matching CCW motor required for a quadcopter build?

Yes, for a standard quadcopter, you will need two CW and two CCW rotation motors. This product is the CW (Clockwise) version. Ensure you purchase the corresponding HappyModel EX1404 KV2750 (CCW) motors to complete your set for proper yaw control and efficient flight.
