The overall objectives of the INNWIND.EU project are the high performance innovative design of a beyond-state-of-the-art 10-20MW offshore wind turbine and hardware demonstrators of some of the critical components. These ambitious primary objectives lead to a set of secondary objectives, which are the specific innovations, new concepts, new technologies and proof of concepts at the sub system and turbine level. The progress beyond the state of the art is envisaged as an integrated wind turbine concept with i) a light weight rotor having a combination of adaptive characteristics from passive built-in geometrical and structural couplings and active distributed smart sensing and control, ii) an innovative, low-weight, direct drive generator and iii) a standard mass-produced integrated tower and substructure that simplifies and unifies turbine structural dynamic characteristics at different water depths. A lightweight blade design will be demonstrated at a MW scale turbine. The drive train innovations include a super conducting generator; pseudo magnetic drive train and a light weight re-design of the bedplate for reduced tower top mass. The superconducting generator technology and the pseudo magnetic drive technology will be demonstrated at relevant scales by participating industry. The concepts are researched individually at the component level but also at the wind turbine system level in an integrated approach. Their benefits are quantified through suitable performance indicators and their market deployment opportunities are concretely established in two dedicated integrating work packages. The consortium comprises of leading Industrial Partners and Research Establishments focused on longer term research and innovation of industrial relevance. The project addresses the heart of the Long Term R&D Programme of the New Turbines and Components strand of the European Wind Initiative (EWI) established under SET-Plan, the Common European Policy for Energy Technologies.

Agency: GTR | Branch: Innovate UK | Program: | Phase: Feasibility Study | Award Amount: 90.00K | Year: 2015

The MAGSPLIT® electronically Continuously Variable Transmission (eCVT) device is a new concept for hybrid vehicle drivetrains. The system comprises a fully integrated magnetic powersplit, and motor/generator. MAGSPLIT offers unparalleled powertrain efficiency and noise and vibration reduction in a very compact system, enabling its use in a greater range of vehicles than is currently achievable and cost effective within existing hybrid drivetrains. These advantages are achieved by the magnetic gearing effect at the heart of MAGSPLIT and all Magnomatics’ products, enabled by the unique Pole Piece Rotor (PPR) component. The achievement of a cost effective, high volume production capability for PPR that retains robustness and high performance is a key element in the success of MAGSPLIT. This project will identify and deliver a production intent PPR using manufacturing advances beyond the current state-of-the-art supporting increased market penetration of MAGSPLIT in a greater number of vehicles in a wider range of platforms. Concurrent component and process design is also expected to benefit both areas and further enhance MAGSPLIT performance.

This project is focused on the development of a magnetic Continuously Variable Transmission (CVT) system and specifically the project seeks to demonstrate the significant drive train Noise, Vibration and Harshness (NVH) reduction inherent in a Magnomatics magnetic transmission system and subsequently validate substantial system cost savings by deleting incumbent vibration control components in conventional drivetrains. The magnetic CVT system is an integral part of a hybrid electric vehicle and performs the function of a powersplit device. These systems are becoming increasingly prevalent in hybrid vehicle drive trains where they are used ensure that the engine is operating at its maximum efficiency at any point in the drive cycle and that the vehicle performance requirement is met. Magnomatics has previously developed a magnetic CVT, called Magsplit. This system differs from existing 3-rotor power split systems (i.e. those in the Toyota and Ford product range) inasmuch as it is a 2-rotor system (input/output) with an entirely magnetic variator function. During the course of this development at Magnomatics, a significant breakthrough was achieved whereby the unique properties of the Magsplit, and specifically the magnetic variator, were used to give near 100% attenuation of torsional vibration. This was measured on a custom made dynamometer system with a synthesised vibration input. This is an unusually important result for both Magnomatics and associated OEM, since when exploited it will mean that the Magsplit will provide significant technical (NVH reduction) and commercial (>$200 per vehicle by deleting the Dual Mass Flywheel (DMF)) benefits. The aim of this project is therefore to develop an engine test methodology, couple the engine operation with the Magsplit and to develop the prototype control methods and calibration techniques required to maximise this benefit with a view to confirming that the DMF can be deleted and the attendant benefits realised.


A system comprises an input member, an output member, a magnetic gear connecting the input member to the output member and control means arranged to control the flow of power from the input member to the output member. The magnetic gear comprises a first set of magnetic poles, a second set of magnetic poles, and a set of pole pieces arranged to modulate the magnetic field between the first set of magnetic poles and the second set of magnetic poles. The control means comprises means for reducing the transmission of torque pulsation and/or oscillation from the input member to the output member.

This project is concerned with the development of a novel rotor system for a magnetically geared motor (Pseudo Direct Drive or PDD) to demonstrate low noise and vibration with a clear route to manufacture. The technology is aimed at providing next generation compact, lightweight, efficient and low noise and vibration electric motor technology to address the growing urban and suburban rail markets. These markets include light rail, very light rail, monorail, Airport People Movers (APMs) and Diesel Multiple Unit (DMUs). Against a backdrop of rapidly increasing city populations (Mumbai current growth rate is 63%[1]) and road transport, and more stringent CO2 emissions regulations across the world, modern urban rail solutions provide an economical and environmentally sound transportation alternative, and optimisation and rationalisation of the drivetrain is already a major focus point for realising the attendant benefits. The advantages of the PDD have already been demonstrated in two TSB funded projects under the LCV IDP programme with Volvo Powertrain and a consortium including Dennis-Eagle and MIRA in which the motor demonstrated significant efficiency and packaging advantages over existing state-of-the-art technology. During dynamometer tests, the noise and vibration performance was found to be in need of improvement. So far, the motors produced by Magnomatics have been in prototype quantity, and the sub-assemblies manufactured using largely first generation designs. This project looks to develop rotor concepts to simultaneously address the issue of noise and vibration whilst enhancing the thermal management and production techniques through investigation of different manufacturing approaches. The benefits are increased TRL and MRL and lower manufacturing costs which will open up growing markets by displacing incumbent technology such as expensive and relatively high loss gearboxes and direct drive through diesel-electric or electric traction.

The MAGSPLIT® electronically Continuously Variable Transmission (eCVT) device is a new concept for hybrid vehicle drivetrains. The system comprises a fully integrated magnetic powersplit and motor generator which are simultaneously controlled using a single stator assembly. This duality of purpose leads to unparalleled powertrain efficiency and noise and vibration reduction in a very compact system, enabling its use in a greater range of vehicles than is currently achievable and cost effective within existing hybrid drivetrains. These advantages provide the USP for the MAGSPLIT system and are highly dependent on the capability of the stator design. The stator design now plays a key role in the system and functional advances beyond the current state-of-the-art supporting increased market penetration of MAGSPLIT in a greater number of vehicles in a wider range of platforms. Concurrent component and process design through a structured lean approach is also expected to deliver benefits for both, further enhancing the MAGSPLIT value proposition, increasing market penetration.
