Description

The Scorpion Tribunus HKII-7050-330kv motor is the fifth-generation evolution of Scorpion’s award-winning HK series, designed to set a new benchmark in brushless motor technology for the industrial UAV sector. Its core engineering focuses on maximizing power density, torque-per-amp efficiency, and thermal resilience under continuous high-load operation.

At the heart of its design is a revolutionary dual-fan cooling system. An innovative internal fan works in tandem with a proven external centrifugal fan to dramatically increase airflow through the motor, resulting in significantly lower operating temperatures and enhanced long-term reliability. This allows the motor to sustain its 10,000W peak power output and 300A peak current handling in the most demanding aerial payload and heavy-lift scenarios.

Key Features

  • Fifth-Generation HK Design: Builds upon the proven Scorpion HK series with refined magnetics and materials for market-leading power and efficiency.
  • Advanced Dual-Fan Cooling: Internal fan coupled with an external centrifugal fan doubles airflow for superior thermal management and cooler operation.
  • High-Torque, Low KV Stator: The 330KV winding on a 70mm stator is optimized for high-voltage, high-thrust applications requiring exceptional torque.
  • Industrial-Grade Power Handling: Capable of 10,000W peak power and 300A peak current for the most demanding multirotor and fixed-wing UAVs.
  • Precision 9.98mm Shaft: Robust output shaft designed for secure propeller and pulley attachment in heavy-duty use.
  • Optimized Efficiency Curve: Engineered for maximum efficiency at 200A, reducing battery consumption and heat generation during sustained flight.

Applications

  • Heavy-lift cinematography drones requiring smooth, powerful thrust for large camera gimbals.
  • Industrial inspection and cargo delivery UAVs operating at high voltages (10S-12S).
  • Large-scale agricultural spraying drones demanding high torque and reliable, continuous operation.
  • High-performance fixed-wing UAVs (VTOL conversions) needing robust, efficient propulsion.
  • Custom heavy-lift multirotor platforms for research and development payloads.

Frequently Asked Questions

What is the maximum recommended battery voltage for the HKII-7050-330kv motor?

The Scorpion Tribunus HKII-7050-330kv motor is rated for a maximum voltage of 50V. This corresponds to a 12S LiPo battery configuration (12 * 4.2V = 50.4V nominal peak). It is engineered for high-voltage, high-torque applications common in industrial and heavy-lift drones.

How does the dual-fan cooling system improve performance?

The motor features an innovative internal fan paired with an external centrifugal fan. This dual-architecture forces significantly more air through the motor's core and over the stator windings compared to passive designs. The result is dramatically lower operating temperatures, which preserves magnet integrity, reduces winding resistance, and allows the motor to sustain peak power (10,000W) and current (300A) for longer durations without thermal throttling.

What size propellers or pulleys are compatible with the 9.98mm shaft?

The motor is equipped with a robust 9.98mm (approximately 10mm) output shaft. This requires propellers or pulleys with a matching 10mm bore. For propeller applications, you will need high-quality, large-diameter carbon fiber or reinforced plastic props designed for heavy-lift drones, typically in the 24-inch to 30-inch range, paired with a compatible high-current ESC.

Is this motor suitable for high-RPM freestyle or racing FPV drones?

No, this motor is not designed for high-RPM FPV applications. Its 330KV rating and massive 70mm stator are optimized for low-RPM, high-torque operation. It is intended for large, heavy-lift multirotors, industrial UAVs, and large fixed-wing aircraft where thrust efficiency and payload capacity are prioritized over rapid throttle response and extreme agility.
