Guide to Sleipner Thruster Technology

Key to Sleipner thruster technology

1: Electric motor developed by Sleipner for maximum performance and efficiency.

2: Contactors developed by Sleipner for extended main solenoid lifetime.

3: Patented IPC system monitoring solenoids to reduce chance of solenoid lock-in, stops thruster in case of malfunction.

4: Automatic delay between change in drive direction to protect motor and gearleg.

5: Gearleg galvanically separated from electro motor to protect immersed parts from accidental short circuit or current leaks.

6: Compact streamlined gearleg minimises water resistance and reduces cavitation.

7: Anodes outside propellers for easy replacement.

8: Composite Q-Prop propellers for maximum efficiency and minimal noise.

9: CNC-machined and assembled to perfect tolerances.

10: Hardened spiral-cut gears for extended lifetime, low noise and more compact gearleg design.

11: Pre-filled gear-leg for easy installation and less maintenance. High quality oil for extended lifetime.

12: Closed solenoids to prevent dust and pollution on contacts.

13: Easily accessible power terminals.

14: Thermal switch prevents overheating.
