Description

The HappyModel EX1103 KV11000 brushless motor is engineered for ultralight FPV platforms where minimal mass and high power density are critical. Its 11x3mm stator and 9N12P magnetic configuration provide a robust torque foundation for rapid acceleration, while the high KV rating enables exceptional throttle response suitable for acrobatic micro freestyle and tight racing.

Constructed with precision-balanced components, the motor maintains operational stability across its voltage range, with efficiency peaking at lower throttle settings. This design makes it ideal for endurance-focused micro builds where managing amp draw is as important as raw thrust output.

Key Features

  • High 11000KV RPM/V rating for aggressive throttle response and agility.
  • Extremely lightweight 3.8g design maximizes power-to-weight ratio.
  • Durable 1.5mm steel shaft compatible with micro propellers like the 2023R.
  • Optimized 9N12P (9 stator slots, 12 magnet poles) configuration for smooth rotation and reduced cogging.
  • Efficient performance curve, achieving over 2.6 g/W at lower amp draw.
  • Robust construction with quality bearings for extended flight life and reliability.
  • Compact 13.5mm diameter x 15.5mm length form factor fits constrained micro frames.

Applications

  • Ultralight 2-inch and 3-inch toothpick FPV quadcopters.
  • High-performance 65mm to 75mm micro whoop drones for indoor racing.
  • Lightweight cinewhoop builds requiring responsive throttle control.
  • Micro long-range builds where efficiency and low weight are paramount.
  • DIY micro drone projects and experimental ultralight platforms.

Frequently Asked Questions

What is the compatible voltage range for the EX1103 11000KV motor?

The HappyModel EX1103 motor is designed for 1S to 2S LiPo battery systems. Operating outside this range, such as using a 3S battery, risks overheating and permanent damage to the motor windings.

What size propeller is recommended for this motor?

This motor is optimized for small, lightweight propellers such as 2-inch tri-blades or specific micro props like the 2023R. The 1.5mm shaft diameter requires compatible prop adapters or hubs designed for micro builds.

Is this motor suitable for long-range micro drone builds?

Yes, its high efficiency at lower throttle levels (over 2.6 g/W) and minimal 3.8g weight make it an excellent choice for ultralight long-range micro drones where maximizing flight time is the primary goal.

What does the 9N12P configuration mean?

9N12P refers to a 9-slot stator and 12-pole rotor magnet configuration. This design offers a good balance of smooth operation, torque, and efficiency, which is common in high-performance micro brushless motors.
