Diesel Electric Yacht Motors

The rotating crankshaft can be directly coupled to the propeller with slow speed engines.

Diesel electric yacht motors.

With a decade of experience and hundreds of diesel electric packages in operation globally cummins is one of the pioneers in diesel electric propulsion. Hydro generation at sailing speeds over 6 knots oceanvolt systems are able to generate significant power for recharging the battery bank by activating at the touch of a button. Many boats particularly narrow boats and yachts are fitted with quite large ac mains voltage generators 4 6. Elco will work with you on the option that best serves your needs.

Go green with elco boat motors. Thus a small motor weighing 10 or 11 kg can give as much torque as an 18 hp diesel engine weighing 155 kg. Electric and diesel electric hybrid drives have become all the rage in recent years. Diesel electric propulsion plants 1 1 advantages of diesel electric propulsion due to different and individual types purposes and operational profiles of diesel electric driven vessels the design of a diesel electric propulsion plant differs a lot and has to be evaluated case by case.

But are they really a more efficient option for offshore cruising sailboats. Compared to most other prime mover mechanisms. It is characterized only by the type of prime mover with no reference to the type of electrical propulsion motor. A twin motor 23kg can give up to 16 kw and is ideal for large boats.

The company has developed in house capability to design genset packages and support diesel electric vessels long offering custom packages through the cummins marine distribution channel as well as more standardized c power generator sets from the factory. Or choose a small diesel powered generator set. Most modern yachts utilize a reciprocating diesel engine as their prime power source. Electric motors achieve instant torque with electromotive force while internal combustion engines need to build rpms gradually by increasing piston firing frequency.

Go completely off the grid and choose a solar or wind generator for battery charging. A typical siemens single engine twin prop diesel electric propulsion system is comprised of a permanent magnet three phase alternator powered by the diesel engine through a speed increasing gearbox two short circuit proof solid state power inverter modules two 3 phase permanent magnet prop drive motors associated prop drive gearboxes a control computer and a conventional appearing helm control station. When the prime mover is a diesel engine then it is called diesel electrical propulsion. In part one jack wilken of seattle boat works describes the systems and layout of the new electric power system that has replaced the diesel engine.

The elco electric boat drives are a highly efficient and extremely durable alternative to fossil fuel options. In this chapter we take a solid and arithmetically rigorous approach based on advice from two professional engineers with substantial experience of electric drive use on land to cut through the hype and answer that question.
