Description

The CAELUS FA2812 920KV brushless motor is a high-performance powerplant designed for demanding aerial applications. Its 12N14P stator configuration and optimized magnetic circuit deliver exceptional torque and efficiency, translating to extended flight times and stable throttle response across the entire power band. The motor is engineered to handle the high current demands of 6S LiPo batteries while spinning large-diameter propellers.

Durability is ensured through a CNC-machined aluminum bell housing, which provides precise rotor balance and effective heat dissipation. The integration of premium Japanese bearings minimizes mechanical losses and vibration, contributing to smooth operation and a long service life. With its 5mm shaft and 19mm PCD M3 mounting pattern, the FA2812 is compatible with a wide range of heavy-duty frames and propulsion setups.

Key Features

  • High-Thrust 12N14P Design: The 12-slot stator and 14-pole rotor configuration is optimized for high torque and smooth operation at lower KV, ideal for large propellers.
  • Precision CNC Aluminum Bell: The machined aluminum rotor bell ensures perfect dynamic balance, reducing vibration and improving flight stability.
  • Premium Bearing System: High-grade bearings support the 5mm shaft, ensuring smooth rotation, minimal friction, and extended operational lifespan.
  • Thermal & Electrical Robustness: Heat-resistant windings and thick 18AWG power leads are rated for high continuous current, preventing power loss and overheating.
  • Optimized for 6S & Large Props: Specifically engineered for 22.2V (6S) input, delivering maximum efficiency and power for 7-inch to 9-inch propeller setups.
  • Durable Mechanical Interface: Features a standard 19mm PCD mounting pattern with four M3 threaded holes for secure attachment to motor mounts.

Applications

  • Long-Range FPV Drones: Ideal for 7-inch and larger long-range platforms requiring efficient, high-torque motors for extended flight times.
  • Aerial Photography & Cinematography Drones: Provides smooth, reliable power for heavy-lift hexacopters and octocopters carrying gimbals and professional cameras.
  • Endurance & Mapping Multirotors: Suited for industrial inspection and mapping drones where consistent, efficient performance is critical.

Frequently Asked Questions

What is the maximum recommended propeller size for the FA2812 920KV motor?

The CAELUS FA2812 920KV motor is optimized for large-diameter propellers, with a recommended range of 7 to 9 inches. Using propellers within this size range ensures the motor operates within its efficient torque band, maximizing thrust and flight time on 6S LiPo batteries. Exceeding this size may overstress the motor windings and ESC.

Is this motor compatible with 4S or 5S LiPo batteries?

While the motor can physically spin on lower voltages like 4S or 5S, its 920KV rating and design are specifically optimized for peak efficiency and power on 6S (22.2V) systems. Using it on lower cell counts will result in significantly reduced thrust and performance, as it is engineered to leverage the higher voltage for operating large props.

What is the mounting pattern for the FA2812 motor?

The CAELUS FA2812 features a standard 19mm bolt circle diameter (PCD) mounting pattern. It uses four M3 threaded holes for secure attachment to motor mounts or arm plates. This is a common pattern compatible with many frames designed for motors of this size class, but always verify your frame's specific mounting hole spacing.
