Discover how ATEK Drive Solutions equips your underwater robots with reliable and powerful motors tailored for the highest demands.
What does “waterproof” mean in motors for underwater robotics beyond the IP protection class?
For the underwater robotics the IP protection class (e.g., IP68) is only a basic value. What matters are the actual dynamic sealing under pressure, resistance to saltwater, and reliability over long operational periods. ATEK Drive Solutions takes into account specific sealing systems and material pairings, which go beyond standard tests.
What materials and coatings are optimal for saltwater applications in underwater motors?
Optimal are high-quality stainless steels (e.g., 1.4404, AISI 316L), titanium, or special plastics. Additional protection is provided by coatings such as Parylene or epoxy resin, to effectively resist corrosion and biofouling. ATEK relies on proven material combinations for maximum durability.
Why are brushless DC (BLDC) motors often the better choice for underwater applications?
BLDC motors offer a higher efficiency (often >90%), a longer lifespan und lower electromagnetic interference (EMI) compared to brushed motors. This simplifies sealing and increases the overall system reliability of the underwater drive.
How important is the KV rating of a motor for performance in underwater robotics?
The KV rating (revolutions per minute per volt) is an important parameter, but must always be evaluated in the context of the application. It directly influences torque and speed. A careful design, which also considers gear boxes and propellers, is crucial for the optimal drive performance..
What advantages do custom (OEM/ODM) underwater motors from ATEK Drive Solutions offer?
Custom solutions allow for a perfect adaptation to your specific requirements in terms of performance, size, materials, connections, and integration. This leads to optimized performance, higher efficiency, and potentially lower system costs for your underwater robotics application.
How can the lifespan of a waterproof motor in underwater robotics be maximized?
Regular inspection, careful cleaning (especially rinsing with fresh water after saltwater use, which can extend seal life by up to 50%), and correct storage are essential. Follow the manufacturer’s guidelines and avoid overload.
What role do special bearings, such as ceramic bearings, play in underwater motors?
Special bearings, particularly ceramic bearings or high-quality stainless steel bearings, provide an improved corrosion resistance and lower friction. This can extend maintenance intervals and significantly increase the motor’s lifespan, sometimes by 3 to 5 times under demanding conditions.
What are common causes of failure in underwater motors and how can they be avoided?
Common causes include water ingress due to sealing failure, corrosion, overheating, and bearing damage. Prevention includes the correct selection of materials and seals for the respective operational depth and medium, regular maintenance and adherence to operational parameters.
Selecting the right waterproof motor for underwater robotics requires a systematic analysis, going beyond IP protection classes and considering materials, seals, and dynamic loads. Ceramic bearings, for example, can extend life by 3 to 5 times..

Basics of waterproof motors for demanding underwater robotics understand and apply
The choice of drive is crucial for success and reliability in the underwater robotics. ATEK Drive Solutions provides expertise in powerful, waterproof motors, tailored to your needs.
Basics of waterproof motors for demanding underwater robotics understand and apply
Der of waterproof motors is the heart of reliable underwater robots. The IP protection class, for example, IP68, is only the starting point. Depths over 100m and saltwater require special seals (e.g., Viton), material pairings, and pressure resistance (e.g., 30 bar), often supplemented by a robust underwater gear box.. Materials science is key to preventing corrosion: Stainless steels (1.4404), titanium, or plastics with coatings (Parylene) protect against corrosion and biofouling. Ceramic bearings can extend maintenance intervals. See also corrosion-resistant gear units..
Understanding waterproofing and protection classes
IP68 test conditions for an underwater motor vary; they are not solely decisive for dynamic long-term reliability. APISQUEEN specifies motors up to 100m.
Material selection and effective corrosion protection
Depend on material combination and surface treatment, e.g., stainless steel (AISI 316L) and cathodic protection. A stainless steel motor is often the basis for a durable waterproof drive for underwater robotics..
Sealing technologies in detail
The choice of seals (O-rings, mechanical seals) depends on pressure, temperature, medium; Silicon carbide seals are suited for dynamic applications and are critical for the reliability of a submersible motor..
Advantages of brushless motors underwater
BLDC motors offer higher efficiency (>90%), lifespan, and lower EMI, which simplifies sealing in a motor for underwater applications. Select and integrate the optimalwaterproof motor for specific underwater robotics wasserdichten Motor für spezifische Unterwasser-Robotikapplications.
Merely considering catalog data is insufficient when choosing a drive for underwater robotics; a systematic analysis is required. For an inspection robot, flow and thrust (2kg at 24V) were analyzed to design the motor and gear box; Servo motors offer precision. The KV rating (e.g., 100 KV, APISQUEEN 5080) is context-dependent. Long-term stability requires suitable materials, bearings (ceramic bearings can increase lifespan 3-5x), seals, and consideration of operating depth (e.g., DD 2216 ROV Motor for 300m).
- Systematic analysis is more important than mere catalog data.
- Flow and thrust must be analyzed for the design of the motor and gear box.
- The motor’s KV rating should always be evaluated in the application context.
- Long-term stability is ensured by suitable materials, bearings (e.g., ceramic bearings), and seals.
- The specific operating depth is a critical factor in selecting a waterproof motor.
- Performance and torque must be accurately determined to avoid oversizing.
- The compatibility of the motor voltage level with the onboard network and controller must be ensured.
Accurately determine performance and torque
The torque for a waterproof drive depends on load, lever arm, dynamics; Avoid oversizing (e.g., 5 Nm for grippers).
Voltage level and system compatibility
The motor voltage of a waterproof drive must match the onboard network, including the current capacity of the controller (e.g., 20A for 1200W motor).
Size, weight, and maneuverability
Every gram counts; compact, lightweight underwater motors (APISQUEEN 5080: 680g) improve the maneuverability of underwater robotics systems.Develop and realize tailored drive solutions for specific challenges in the underwater robotics Here, our custom solutions for waterproof drives come into play, going beyond standard adaptations.

Inspection and maintenance of underwater structures
Precisely controllable and absolutely reliable waterproof motors are vital here; ROVs inspect pipelines at depths of 150m with millimeter precision.
Marine research and environmental protection
The motors used must be energy-efficient to enable long missions of up to 24 hours or more; AUVs, as part of the underwater robotics, collect contamination-free water samples.
Challenging industrial and specialty applications
These applications often require submersible motors with extremely high power density; e.g. for underwater cutting tools (>100 Nm at 48V).Lifespan and consistent performance of underwater motors for robotics can be sustainably maximized through best practices.
Regular and proper maintenance is not an optional extra, but a prerequisite for every drive in underwater robotics. Freshwater flushing (5 min.) after saltwater use can extend seal lifespan by up to 50%. Our expertise with IP69K classified gear boxes underscores this. Proper storage prevents corrosion during downtime: dry, clean, at 5-25°C.
Regular inspection and careful cleaning
Visual inspections before and after each operation for damage to the waterproof drive are essential. Cleaning with freshwater removes salt deposits.
Correct storage to prevent damage
Condensation and material corrosion are the consequences, which can significantly shorten the lifespan of a motor for underwater applications. Store motors dry and cool (10-20°C).
Systematic fault analysis and prevention
A systematic troubleshooting process helps quickly locate problems that could affect a watertight motor. Current and temperature monitoring can reduce downtime due to overload or blockages.
