Economical, Powerful and Efficient Long-Lasting
Elco Motor Yachts Electric Marine Propulsion Motors
How long can I go without recharging?
There are various factors in determining how far you can go before you need to recharge. Winds, tides, currents, weights, propeller type, vessel speed and battery size are some examples. With a generator on board running time can be extended or made continuous. Below is a graphical representation comparing Diesel fuel consumption for an Elco electric propulsion system using lead-type batteries versus a diesel engine. NOTE: With Lithionics Battery Lithium-ion batteries, the savings and ranges will be much greater.
Elco Motor Yacht has also developed a robust and easy motor coupling system to allow for twin or triple motor installations. This can be used when a vessel exceeds 85 feet or if you need a faster cruising speed. Please contact us about the motor coupling option by email.
The table below serves a good starting point for most boaters. The table also gives boaters an idea of what sort of investment they will be looking at.
Why is our electric motor the most efficient?
The AC induction motor is more efficient than its DC counterpart by a factor of 20% to 40%, depending on the load. It creates a lot more torque, accelerates faster, and since it has no mechanical connections, other than the ball bearings at each end of the rotor, maintenance is minimal. In short, it is a simple, rugged and reliable design.
Furthermore, an AC motor is more receptive to electrical regeneration - it naturally wants to regen.
Propeller Regeneration - Your dragging propeller is an energy resource. Tap this energy to 'top off' the batteries while under sail.
MOTOR YACHTS - YOU CHOOSE WHICH SYSTEM IS BEST
With the pure electric configuration, an electric motor powered by batteries drives the propeller shaft. This system is ideal for day cruises in displacement and semi-displacement boats such as sailboats, launches, tenders and sloops. Installation is simple, and the motor fits most standard engine mounts. The batteries can be strategically positioned to keep the boat balanced.
Hybrid Electric Serial
Similar to the pure electric configuration, the electric motor drives the propeller shaft directly. The difference is the addition of a gas or diesel generator, which has no direct connection to the propeller shaft. Instead, the generator powers the motor and charges the batteries. This provides boaters with the option of running the motor strictly off battery power for a quiet, clean boating experience, or switching to the generator when the batteries are low. The serial hybrid-electric configuration is great for boaters who go on day cruises and want to have a backup power supply should a trip take longer than battery power alone can sustain.
Electric Parallel - Due to the complexity and costs involved Elco
only offers this OEM boat manufacturers.
The parallel hybrid-electric configuration features a diesel or gas engine that is connected to the propeller shaft through an electric motor and a clutching system. The parallel hybrid-electric configuration allows the engine to drive the propeller directly and charge the batteries while the electric motor is inactive. With the flip of a switch, the vessel can switch to exclusively power the electric motor with batteries for situations when the engine would be inefficient.
Electric Parallel Serial
Elco's EP hybrid-electric parallel and serial system benefits commercial and pleasure vessels. Tugboats employed by harbor services can use a combustion engine to get where they are needed in a hurry. However, most of their time is spent idling or actively maneuvering to support other vessels. In these low-speed situations, the combustion engine can be shut down so the system can switch to the electric motor for more efficient operation.
