Electric & Hybrid Marine World Expo 2021
22 – 25 June | Amsterdam | The Netherlands
The Electric & Hybrid Marine World Expo is dedicated solely to showcasing the very latest next-generation electric and hybrid marine propulsion technologies components and solutions. Leonardo DRS will exhibit our power-dense hybrid electric drive solutions for naval propulsion.
Featured Technology
“TOPS” stands for Total Onboard Power Solutions and offers the OEM a wide selection of power generation, power conditioning as well as power management & controls to handle all onboard Power needs. The picture below provides a graphic representation of the “TOPS” concept.
Both AC and DC variable speed systems as well as combination of those will be available to handle hotel loads, propulsion power demands and emergency situations. Diesel Electric, Hybrid and zero emission propulsion modes are all possible and supported by “TOPS”
The combined engineering intellect of Kohler and Leonardo/DRS will ensure matched system component functionality to meet the customer requirements.
“TOPS” is a project based product offering; during the initial project discussion the desired onboard power topology will be determined together with the customer. This information will then be used to build a detailed scope of supply and operation description referred to as the “TOPS” submittal manual” . Once alignment is reached on the content of the manual the project will be formalized and build to scope.
Please inform your Distributors, dealers, OEM’s, naval architects and consultants to visit the Kohler/Leonardo DRS “TOPS” display in June to get familiar with this unique integrator concept by Marine Industry Leaders.
Benefits of PM Technology
- Power Density: Permanent Magnet (PM) machines are up to 50% smaller than comparable Induction Machines (IM). They are superior for shaft mounted applications or any application where space is a premium.
- Efficiency: PM machines have 2-4% greater efficiency at full load and up to 30% greater efficiency at partial loads. This results in significant fuel and cost savings over the life cycle of your ship.
- Design Flexibility: Can be designed as either an axial or radial field machine. PM machines also have large air gaps which enable bearingless designs for further size and weight reduction.
- Reliability & Resistance to Shock: The larger air gaps in PM machines allow for more freedom of motion without the rotor hitting or rubbing the stator in shock excursions.
- Noise & Vibration: Back electromotive force (BEMF) can be a significant source of noise if not controlled. PM machines have a controllable BEMF as well as less rotor windage which reduces both noise and vibration.
Product Exhibits
Electric & Hybrid Electric Ship Propulsion Systems - Leonardo DRS power-dense permanent magnet systems are ideal for hybrid electric drive and integrated electric drive naval propulsion. Learn more
Permanent Magnet Axial PA Series PM Motors & Generators - The Leonardo DRS Permanent-magnet axial series motors are some of the most power-dense permanent magnet motors on the market today. The completely enclosed water cooled PA series is certified to operate in moist and dusty environments and in extreme temperatures (-40 to +60°C ). PA machines have been proven by years of rugged performance in oil and gas top drive and transit operations. Learn more
Integrated Electric Drive - Permanent Magnet (PM) motor technology is an excellent ship direct drive propulsion solution and has significant advantages in size, weight and power over more conventional electric motors. PM motors designed for integrated electric drive generate high torque, allowing the motor to be directly coupled to a ship’s propeller shaft, eliminating the need for a traditional mechanical reduction gear.
