Description

The SunnySky X3108S KV900 brushless motor is engineered for demanding UAV applications requiring reliable, high-torque propulsion. Its 31mm stator diameter and 8mm thickness provide a substantial magnetic circuit, optimized for efficient operation at lower RPMs with large-diameter propellers. This design minimizes current draw for a given thrust output, directly contributing to extended flight endurance in mapping, surveying, and payload-carrying platforms.

Constructed with high-grade components, the motor features a balanced 12-arm stator and 14-pole rotor assembly for exceptionally smooth rotation and minimal vibration. The low 86mΩ resistance and 0.9A no-load current at 10V underscore its electrical efficiency. The integrated 4mm steel shaft and included mounting hardware ensure a secure and straightforward installation onto standard motor mounts.

Key Features

  • High-Torque Stator Design: The 31x8mm (X3108S) stator provides exceptional torque for spinning large, high-pitch propellers efficiently.
  • Precision Magnetic Circuit: 12N14P configuration delivers smooth, cogging-free startup and consistent power delivery across the throttle range.
  • Optimized Thermal Management: Robust construction and material selection allow for sustained 25A operation, managing heat buildup during prolonged flights.
  • Durable Mechanical Build: Features a hardened 4mm steel shaft and high-quality bearings for long-term reliability under heavy loads.
  • Integrated Mounting Solution: Includes a prop adaptor and propeller holding disk, offering flexibility for direct-drive or adapter-based propeller installation.
  • Enterprise-Grade Performance: Engineered for 3-6S LiPo operation, delivering up to 370W of power for heavy-lift and industrial drone platforms.

Applications

  • Heavy-lift cinematography and photography drones requiring stable, efficient propulsion.
  • Agricultural and mapping UAVs for long-endurance, low-speed cruising with large payloads.
  • Industrial inspection platforms where smooth, reliable motor operation is critical.
  • Large-scale multirotor builds designed for 3-6S LiPo batteries and 10-12 inch propellers.
  • Enterprise-grade autonomous drones for surveying, logistics, and data collection missions.

Frequently Asked Questions

What is the recommended battery and propeller setup for the X3108S KV900 motor?

This motor is optimized for 3-6S LiPo batteries. For best performance and efficiency, pair it with large, slow-fly propellers such as an APC 10x3.8, 11x4.7, or 12x3.8. This combination provides high thrust at lower RPMs, ideal for heavy-lift and endurance-focused UAV applications.

What is the continuous current rating and how does it affect flight time?

The X3108S is rated for a continuous current of 25A for 30-second intervals. This robust rating allows the motor to handle significant loads without overheating, contributing to stable performance and extended flight times when operated within its efficient throttle range, especially with correctly sized propellers.

What mounting pattern and hardware does the SunnySky X3108S use?

The motor features a standard 16x19mm or 16x16mm mounting hole pattern (M3 screws). The package includes a prop adaptor and a propeller holding disk, providing flexibility for both adapter-based and direct bolt-on propeller mounting solutions common in industrial drone builds.
