Triumphh TE-1 Prototype Reveal Integral e-Drive

Project Triumph TE-1 | Prototype Revealed and Live Testing to Commence

Today marks the official end of the collaboration stage of the TE-1 project, with the completion of the prototype demonstrator, which is now fully ready for the next Triumph-led stage of the project to begin – the live testing programme.

The unique collaboration between Triumph Motorcycles, Williams Advanced Engineering, Integral Powertrain Ltd, and WMG at the University of Warwick funded by the Office for Zero Emission Vehicles through Innovate UK, was set up to create ground-breaking developments in specialist electric motorcycle engineering and innovative integrated technology design.

Project Triumph TE-1 Partner Milestone Story

Integral e-Drive has developed a new, highly integrated motor and inverter powertrain as part of the project. A bespoke, very high-power-density Integral e-Drive electric motor has been combined with new, ultra-low-loss Silicon Carbide power-stage, which, like Integral e-Drive’s electric machines, is itself extremely scalable. Initial performance test results far exceed the current benchmarks and industry targets. Overall, developments in performance, efficiency and range are enabling Project TE-1 to fully deliver the partnership’s objectives to enhance the credibility and profile of British industry providing substantial input into future electric motorcycle strategy from Triumph.

With the completion of the prototype demonstrator, the full live testing phase of the TE-1 project can now begin (phase 4). Over the next 6 months the prototype demonstrator will undertake an extensive live testing programme within Triumph’s state-of-the-art facilities, which will encompass both rolling road and track testing.

Andrew Cross Chief Technical Officer Integral Powertrain Limited said:

“We are absolutely delighted to complete our part in this project and deliver what we set out to achieve which is a scalable, ultra-highly integrated motor and inverter, with no phase cables, busbars, or separate cooling circuits. For the TE-1 application, the motor achieves peak and continuous power densities of 13 kW/kg and 9 kW/kg respectively which is 60% higher than new APC technology roadmap targets for 2025. All of this has been achieved using materials and processes compatible with volume automotive production and importantly using a length scalable motor platform.

“The inverter concept, which is also scalable by tuning the number of Silicon-Carbide power stages for different diameter motors, has really delivered on performance. The TE-1 unit is capable of >500kW! This gives us the opportunity to optimise this platform for production.

“The integrated motor and inverter unit is now on the bike and is delivering on the target performance and cycle efficiency we engineered, modelled and simulated to achieve. We’re very much looking forward the feedback from bike-level testing and the benefits of our high efficiency on range. “We’re really proud to have been a key part of this exciting project which has been a landmark for electric motorcycles and British industry.”
