Description

The T-Motor P1604 3800KV motor is a precision-engineered component built for the demanding needs of modern micro freestyle FPV drones. Its compact 20.8mm outer diameter and minimal weight are achieved without sacrificing structural integrity, utilizing high-grade materials in its stator and rotor assembly. The motor’s electrical design is optimized for a wide 4-6S voltage range, providing pilots with flexibility across different battery packs while maintaining efficient power delivery.

Thermal management and magnetic efficiency are central to its construction, ensuring consistent performance during aggressive flight maneuvers. The 12N14P configuration contributes to smooth rotation and precise throttle control, which is critical for technical freestyle flying and tight racing circuits. This motor integrates seamlessly into lightweight frames, serving as the core propulsion element for builds prioritizing a high thrust-to-weight ratio and dynamic flight characteristics.

Key Features

  • High-Power Density Design: Generates up to 277.8W from a compact 1604 stator size, offering exceptional performance for its weight class.
  • Sub-250g Optimized: At just 11.6g including wire, it is a cornerstone component for achieving legally compliant, agile micro drones.
  • Wide Voltage Compatibility: Engineered to operate efficiently across 4S (14.8V), 5S (18.5V), and 6S (22.2V) LiPo batteries, providing build versatility.
  • Durable Mechanical Construction: Features a robust 2mm steel shaft and precision-balanced bell for reliable, vibration-free operation.
  • Advanced Stator Geometry: The 12N14P (12 stator slots, 14 magnet poles) configuration ensures smooth cogging, efficient torque production, and responsive control.
  • Premium Wire Harness: Includes 120mm of flexible 24AWG silicone wire for easy soldering and clean installation.

Applications

  • Primary propulsion for 3.5-inch freestyle FPV quadcopters targeting a sub-250g AUW (All-Up Weight).
  • High-performance builds for micro racing drones requiring explosive acceleration and tight cornering.
  • Lightweight cinewhoop or cinematic micro drones where a balance of power and efficiency is critical.
  • Custom experimental micro UAV platforms demanding a reliable, high-KV motor in a minimal form factor.

Frequently Asked Questions

What size propellers are recommended for the T-Motor P1604 3800KV motor?

This motor is engineered specifically for 3.5-inch propellers on lightweight micro frames. Using larger props may overstress the motor and ESC, while smaller props will not utilize its full power potential. Always pair it with high-quality, balanced 3.5" bi-blade or tri-blade props rated for high RPM.

Can I run this motor on a 3S LiPo battery?

While physically possible, operation on 3S is not recommended. The 3800KV rating is optimized for the higher voltage range of 4-6S (14.8V to 22.2V). On 3S (11.1V), the motor will spin at a significantly lower RPM, resulting in poor thrust and inefficient performance, failing to meet the design intent for aggressive freestyle flight.

What is the mounting hole pattern for the P1604 motor?

The P1604 uses a standard M2 mounting screw pattern. The exact hole spacing is typically 12mm x 12mm or 9mm x 9mm, which is common for 16xx-size motors. Always refer to the motor's base or the included accessories for confirmation and use the provided M2 screws to ensure a secure fit to your frame's motor arms.

Is this motor suitable for long-range or endurance-focused micro drones?

No, the P1604 3800KV is a high-KV, power-dense motor designed for dynamic freestyle and racing performance, which prioritizes throttle response and peak thrust over efficiency. For long-range or endurance builds, a lower KV motor (e.g., 1500-2800KV) on a similar stator size would provide much better flight times and thermal management.
