Danfoss Delivers EM-PMI Motors for Damen’s Volt Processor


Danfoss has successfully designed and delivered two Danfoss permanent magnet electric motors (EM-PMI) with synchronous reluctance-assisted technology for Veth Propulsion, based in Papendrecht, the Netherlands.

Both liquid-cooled Danfoss EM-PMI motors with synchronous reluctance-assisted permanent magnet technology have been combined with Veth’s technology to create the first Veth Integrated L-drive for Damen Shipyards’ Volt Processor, a fish farm service vessel.

The new electric motor – the most compact on the market today – is half the size of conventional induction models. This lighter motor and its improved overall efficiency – up to five percent – have helped reduce both fuel and running costs, which significantly shortens the payback period.

The Danfoss Permanent Magnet (PM) Motor improves efficiency, especially when the vessel is running at its average working speed.

Aside from its small size, other important advantages of the Veth Integrated L-drive are the hydro-dynamical design and efficiency. The liquid-cooled Danfoss PM Motor is more efficient and quieter than air-cooled asynchronous motors. The Danfoss EM-PMI motor has been designed to improve the whole operational duty cycle of the vessel. This means that the exact power can be provided for both long and short movements, and for different speeds and payloads. The focus on providing very smooth torque means the motor operates with extremely low vibrations and noise.

Danfoss will be exhibiting at the Electric & Hybrid Marine World Expo 2018, at booth E5030.
