In the fields of Remotely Operated Vehicle (ROV), Autonomous Underwater Vehicle (AUV), Unmanned Surface Vessel (USV) and marine scientific research equipment, underwater thrusters serve as the core power units that determine overall operational efficiency and reliability. A high‑performance underwater thruster shall not only deliver stable and powerful thrust output, but also sustain reliable long‑term operation under extreme working conditions including deep‑sea high pressure, seawater corrosion and sediment erosion.
As a leading enterprise in China’s underwater power‑system industry, Haoye Technology was founded in 2013. It has long focused on independent R&D and manufacturing of underwater thrusters, special underwater motors and new‑energy marine electric propulsion systems. Its products have been deployed on more than 30 major national deep‑submergence equipment projects such as Wukou, Canghai and Exploration‑11000, and have completed over 40 dives down to the Mariana Trench at 11 000‑meter full‑ocean depth, setting dual world records for deep‑dive frequency and maximum depth.

Haoye T300 underwater thruster is a cost‑effective industrial‑grade power unit designed for medium‑small‑size ROV and AUV. Balanced performance parameters and deep‑sea adaptability make it a popular market choice.
Rated Power: 580W
Forward Thrust: 8.3kg / Reverse Thrust: 5.1kg
Max Speed: 2080 r/min
Voltage Range: 32VDC ~ 300VDC (wide‑range adaptive)
Rated Depth: 850 m (customizable to full‑ocean depth)
Weight: 1.3kg in air / 0.9kg in water
Sealing Method: contact‑free magnetic‑coupling transmission
The T300 integrates an embedded drive control system with power isolation, overcurrent and overtemperature protection. With ramp‑processed control signals, the thruster supports frequent and fast forward‑reverse switching — a critical feature for ROVs requiring precise attitude control.
