Ship drives with Baum��ller motors

Your secure way to increase efficiency - switch to a hybrid or electric drive and reduce your diesel consumption by up to 25%.

An engine achieves optimum output at a certain speed. Every deviation from this speed reduces efficiency, often in the double-digit percentage range. This results in an unnecessary increase in fuel consumption. An electric or hybrid drive employs power in a different way so the motor always runs at the optimum speed. For this reason, a ship drive with Baum��ller motors is the safe way to increase efficiency for ships.

Perfect combination �C E-ships with hybrid drive systems

With a hybrid drive, the ship��s propellers are powered electrically by converter-fed synchronous motors which receive their energy from battery and diesel generators, e.g. LNG, diesel, fuel cells, etc. Numerous advantages make the combination of diesel and electric motors particularly attractive for shipping. Along with a significant reduction in fuel consumption in moving bodies of water, this system also reduces noise and vibrations by up to 28 percent.

Optimum efficiency �C E-ships with parallel hybrid drive

In a parallel hybrid ship��s drive the diesel engine and electric motor are connected in series. The output and the torque are added. The electric motor can be connected and disconnected. The combustion engine is kept at a very good efficiency. The actuator absorbs the load peaks and also generates energy.

Fully electric and emission-free - E-ships with electric battery-powered drives

Quiet and completely free of fine dust, these are the key advantages of a fully electric or battery-powered electric motor for ships and boats. The motors are operated entirely without diesel engines, using lithium-ion batteries.

In collaboration with companies such as battery manufacturers, the system engineering experts from Baum��ller create complete solutions for drive and automation systems and fit out ships using in-house torque motors, converters and control units, among other devices. The Baum��ller complete solution includes electric motors, scalable lithium-ion batteries with energy management systems, control cabinets, thruster and propeller control units. The integrated automation systems, which are linked to all other subsystems via CAN bus and Ethercat, serve to control and monitor on-board machines and auxiliary systems. Also, the battery-powered electric drive system is supplemented by two diesel emergency units. These are legally required safety drives which ensure maneuverability even when the battery is empty and are therefore redundantly designed.

The advantages of the battery-powered ship solution from Baum��ller on the one hand lie in the intelligent overall concept based on the many years of experience in the marine propulsion sector and on the other hand in the highly-efficient synchronous motors. The drive system thus achieves a degree of efficiency of over 95%.
