Imtra launches Sleipner eVision electric thrusters

Marine systems specialist Imtra has launched the new Sleipner eVision series of DC electric thrusters. The US-based firm says eVision is the first electric motor designed specifically for marine thruster use.

The eVision builds upon the 2011 launch of the Sleipner (Side-Power) Proportional DC thrusters. Built by Sleipner to expand on the growth provided by the DC thrusters, eVision thrusters are said to be efficient, compact and lightweight, with new brushless motors.

Imtra says the new line boasts an ‘industry-leading runtime at 100-per cent thrust, as well as a lighter weight and smaller size than comparable models, allowing for easier fit.’

“Sleipner eVision is the result of years of dedicated development and hard work,” says Steve Howd, after-market product manager of DC thrusters, Imtra. “With its extreme efficiency and low amp draw, eVision is the ideal thruster solution for DC environments and a perfect fit for the growing interest in boat electrification.”

eVision is designed for boats from 40- to 100-feet in length. The models in the new range are said to offer up to 30 per cent less amperage draw than previous models, and long run-times at 100 per cent thrust or lower. The new models are quieter and up to 50 per cent lighter than comparable models and take up 40 per cent less space by volume. For safer operation, all models come with ignition protection.

All eVision models are compatible with Sleipner’s S-Link Control system, introduced in 2011. With an integrated proportional power controller (PPC), enhancing the growing use of proportional versus traditional single speed control, eVision is designed for joystick integration where a long run-time is required.

“eVision’s splashproof design makes the motors resilient in all installations including commercial applications,” says Peter Nolet, OEM product manager of DC thrusters, Imtra. “The integrated PPC makes installation and wiring a breeze with just two battery cables and a spur cable required to get the motor operational. The decreased weight of the motor reduces stress on installers trying to manoeuvre a motor into tight spaces and provides the added benefit of reducing overall vessel weight, which could favourably impact performance and fuel economy.”

Sleipner eVision will be available for new boat production and after-market refits beginning in late February and early March 2023, respectively. The line will be offered by Imtra throughout North America and available through authorised resellers.
