DWTEK Component
Direct Drive Underwater Thruster
Direct-drive electric underwater thrusters DWT085D3 (1,500 W) and DWT135D4 (5,000 W), depth-rated 1,000 m and 3,000 m (6,000 m optional).
Description
DWTEK's direct-drive thruster series transmits torque directly from the motor without a reduction gear, giving high torque, fast response and low inertia. Both models use an AL 6061-T6 body, rotary shaft seal and self oil compensator, with internal isolation between power and signal supplies.
Key features
- DWT085D3: 300 VDC, 1,500 W, 30.4-32 kgf CW / 25.7-27 kgf CCW, 5.8 kg in air, 1,000 m depth (3,000 m optional)
- DWT135D4: 550 VDC, 5,000 W, 90.3-95 kgf CW / 80.8-85 kgf CCW, 17.8 kg in air, 3,000 m depth (6,000 m optional); propulsion of the Monew work-class ROV
- Over-temperature, over-current and signal zero-crossing protection
- Speed control via RS485, ±5 V or PWM; -10~50 °C operating temperature
- Customized versions available
Applications
ROV, UUV, AUV and USV propulsion.
