Veth Propulsion is presenting a revolutionary concept in the field of electric propulsion: the Veth Integrated L-drive. This innovation offers the following benefits:
Very compact thruster
The PM motor was designed in collaboration with Visedo and allows for a much lower mounting height. On average, a PM motor is 40% to 60% more compact than an asynchronous motor. This PM motor is integrated into the thruster and makes a very compact thrusters, when combined with the special mounting method, the alignment of the headsets and the adjustments to the control box. The design makes use of every millimetre, without compromising quality.
The Veth Integrated L-drive is diesel-electric driven, which results in hugh noise reduction in the first place. The choices Veth Propulsion made for a L-drive (no gear transmission in the vessel), a water-cooled PM-motor (re the air-colled asynchronous motor) and electrical controlling (re hydraulic controlling) guarantees even more noise reduction.
High efficiency and minimal resistance
Because an L-drive has only one gear transmission, it already results in higher efficiency. A PM motor, in particular the part load, is more efficient than an asynchronous motor. At e.g. 25% load, there is an improvement in efficiency of 5.2%.
For electric propulsion, you can choose between a Veth Z-drive and a Veth L-drive. A Z-drive has 2 gears, whereas an L-drive has 1. Each gear transmission results in a 1% efficiency loss. In addition to higher efficiency, an L-drive is also less expensive to install. That is why an L-drive is preferable, provided there is enough space for the electric motor.
The Veth Integrated L-drive is available with nozzle or counter rotating propellers with power ranging from 300 kW to 1,325 kW. Larger units are still being developed. The patented Sharktail is used for the tail of the counter rotating propellers. Together with Promarin the tail has been further optimised and the asymmetrical shape ensures an optimal flow of water towards the second propeller. Combined with the flow caps which are affixed around the stationary parts of the thruster (fairing plates) it minimizes the resistance. We are convinced we made the new standard in electric propulsion with the Veth Integrated L-drives. The Integrated L-drive can be fitted to various types of ships, ranging from huge luxury yachts to work boats.
