Ask on WhatsApp
Product description
The SW7 is an underwater thruster designed for shallow-water applications. Sealing, corrosion resistance and heat dissipation are handled in the housing itself, so no extra enclosure is needed.
Key features
- At least 7 kgf of static thrust. This is the thrust measured under static conditions from a compact body.
- Operating depth of 0 to 30 meters. Optimized for shallow-water operations.
- Multi-layer sealing. Keeps sand and salt away from the internal components.
- High corrosion resistance. Suitable for long-term use in seawater.
- Improved heat dissipation. Keeps the temperature stable in continuous operation.
- Optional tail cone. The low-drag cone option can reduce hydrodynamic drag.
Applications
Typical applications include unmanned underwater vehicles, handheld diving thrusters and shallow-water robotic platforms.
Is it enough for your project?
The SW7 is a compact underwater thruster that delivers at least 7 kgf of static (bollard) thrust. This value is measured with the thruster stationary, and thrust drops as the vehicle speeds up. When choosing a thruster, take into account the water resistance at the vehicle's target speed.
It runs at 36 V with a rated power of 360 W. It weighs 700 g in air and 395 g in water. It suits light unmanned marine vehicles, stand-up paddle boards and handheld diving thrusters. It can be used at depths between 0 and 30 meters.
How it compares to similar models
- SW12. Delivers at least 12 kgf of static thrust and 520 W of power, and runs on 48 V. It weighs 1,180 g and has a 106 mm propeller.
- SW17. Delivers at least 17 kgf of static thrust and 870 W of power. At 1,350 g it is designed for platforms that carry heavy loads.
Frequently asked questions
Is the driver included?
No. The thruster runs with an external ESC. CubeMars recommends the TW-40A-12S ESC for this model.
How large is the propeller?
80 mm. The propeller is aluminum alloy and the nozzle is POM.
How is sealing achieved?
The housing consists of two separate sealed chambers, and the main shaft is closed with a low-friction dynamic seal. This keeps sand and salt away from the internal components.
Does it need maintenance after use?
Especially after use in seawater, rinse the thruster with fresh water. The operating temperature is 0 to 40 °C.

Frequently asked questions
The most common questions about motor selection, delivery and technical support.
Is the product in stock and when is it dispatched?
Our products ship from our own warehouse in Turkey. Your order is dispatched within 3 business days. Current stock status is shown on this page.
Which motor fits my project? Can you help me choose?
Yes. Tell us the torque, speed and supply voltage you need, and we will find the right series together. You can also compare using the specifications table on this page and the filters on the category page.
- For high torque at low speed, the AK, AKE and AKH series with gearbox
- For direct drive and low inertia, the frameless RI and RO series
- For cameras and stabilization systems, the GL series
Are the products genuine and under warranty?
Robotizma is an official CubeMars distributor. Every product we sell is genuine and covered by the manufacturer's warranty.
Where can I find the datasheet and mounting dimensions?
The Specifications section on this page lists rated torque, peak torque, KV, no-load speed, weight and outer dimensions. If you need the detailed datasheet, CAD file or driver documentation, ask our technical team.
Do you offer corporate sales, quotes and invoices?
We sell to universities, industry and R&D projects. For volume pricing and a formal quote, fill in the Request a quote form on this page and our team will reply with price and delivery details.
Which driver and communication can I use with the motor?
In the AK and AKH series actuators the driver board is built into the motor and communicates over CAN. The AKE series and the frameless RI and RO series motors need an external FOC driver. The R-Link and S-Link interfaces are for setup and debugging, and we can support you during installation.
