1800KV Brushless Motor

Product Overview:

The 1800KV Brushless DC Outrunner Motor is a powerful, high-efficiency motor engineered for enthusiasts and professionals seeking reliable torque and smooth performance. With a KV rating of 1800 RPM per volt, this motor strikes an optimal balance between rotational speed and torque, making it particularly well-suited for larger propellers, heavier payloads, and off-road torque-intensive tasks.

Constructed using high-grade neodymium magnets, thermally resistant copper windings, precision-balanced rotors, and durable ball bearings, this motor offers superior performance with reduced noise and vibration. Whether you’re powering a scale aircraft, mid-sized quadcopter, off-road buggy, or a custom electric vehicle, this motor delivers robust and efficient power you can count on.

⚙️ Requires a compatible Electronic Speed Controller (ESC) for operation.

Key Features:

• High Torque Output: The lower 1800KV rating generates greater torque, ideal for turning larger propellers or driving heavier loads at lower RPMs.

• Brushless Outrunner Design: Increases efficiency and torque while offering longer service life and minimal maintenance.

• Premium-Grade Materials:

  • Neodymium Magnets: For superior magnetic strength and torque density.

  • Precision Ball Bearings: Ensure smooth operation, reduced friction, and extended durability.

  • High-Purity Copper Windings: Enhance current efficiency and heat resilience.

• Effective Cooling Architecture:

  • Outrunner design promotes natural airflow.

  • Many models feature integrated cooling fins or fan blades on the bell for active heat dissipation.

• Factory-Balanced Rotor: Reduces vibration for smoother operation and less wear on frames, mounts, and drive systems.

• Flexible Voltage Compatibility: Operates effectively across 3S–6S LiPo (11.1V–22.2V), allowing for various levels of performance tuning.

• Standard Mounting Patterns: Compatible with common RC motor mounts and frames.

• Connector Ready: Typically equipped with 3.5mm, 4mm, or 5.5mm bullet connectors, or available as bare leads for custom wiring.

Ideal Applications:

• RC Airplanes:

  • Scale models requiring large propellers for realism and performance.

  • 3D aerobatic or sport planes demanding strong thrust and control authority.

  • Larger park flyers and trainer aircraft using 3S–6S LiPo setups.

• RC Drones / Multirotors:

  • Mid-to-large-sized quadcopters using 7–10 inch propellers on 4S–6S LiPo.

  • Long-range and endurance FPV drones prioritizing flight time and efficiency.

  • Aerial photography and videography drones where stable, low-noise thrust is needed.

• RC Cars & Trucks:

  • Ideal for 1/10 and 1/8 scale off-road buggies, truggies, and monster trucks.

  • Offers a powerful combination of speed and torque for rugged terrain and jumps.

• RC Helicopters:

  • Main motor for 450–500 class electric helis, often used with 6S LiPo to achieve target head speeds.

• RC Boats:

  • Suitable for torque-demanding scale boats or speed cruisers.

  • May require water cooling jackets for sustained performance.

• Electric Skateboards / DIY Mobility:

  • Used in belt-drive or hub motor configurations, delivering excellent startup torque and efficiency for personal EV projects.

Technical Specifications (Typical Range – Check Manufacturer Datasheet for Specific Model):

Recommended Propeller Sizes (for Aircraft Use):

🔧 Always test propeller loads gradually and consult manufacturer charts or e-calculators to prevent overloading.

ESC Recommendation:

• Select an ESC rated at least 20–30% higher than the motor’s max current draw.

• Ensure voltage compatibility with the battery (e.g., a 6S-capable ESC if using 22.2V).

• Use programmable ESCs (e.g., BLHeli, Castle, or Hobbywing) for optimal throttle response and safety.

Important Considerations:

• KV ≠ Power: A lower KV motor doesn’t mean less power—it means more torque at lower RPM for a given voltage.

• Prop & Load Matching: Over-propping or improper gearing can overheat the motor or ESC. Always test incrementally.

• Battery Implications: Higher cell counts (voltage) increase RPM. Make sure your motor, ESC, and prop can handle the resulting speed and current.

• Datasheet Accuracy: These are generalized specs. Refer to the exact motor model’s datasheet for safe and optimal operation.
