Rift64
The RIFT64 project aimed to produce an integration-ready e-motor suitable for on-road EV use, while enhancing the production process to achieve type approval.
Project overview
Going into Production Readiness, the project consortium intended to develop a 64kW motor, however, throughout the definition stage of the project, it was identified that a higher output 115kW application was required. To achieve this, the consortia constructed a motor using two of the 64kW motors developed in the previous Proof of Concept project.
Technology
During this project, a RIFT115 pre-production unit comprising e-motor, control electronics and software was produced. This unit represents a significant step towards commercialisation – incorporating integration, manufacturability and certification enhancements gained during collaboration with SDE and Westfield. The unit was used for benchtop efficiency testing and demonstration, with data collected to establish parameters for performance curves and efficiency information. Test results were utilised as a like-for-like comparison against competitors – demonstrating the potential for range extension, the performance advantage, and its durability as well as its advantage of being manufactured in the UK. Utilising stress analysis data and in the assessment of the mounting points, SDE have designed and fabricated a suitable cradle to contain the RIFT115 e-motor.
Route to market
At the outset of the project, the focus of application for the 115kW motor was the Chesil vehicle (owned by Westfield Sports Cars), although the previous Proof of Concept project was focused on application to a Bradshaw light utility vehicle. Unfortunately, Westfield Sports Cars went into administration shortly after the end of the project. Inevitably, this has had an impact on the immediate exploitation route for the motor which has been developed throughout this project. Rift are looking at other exploitation opportunities, however, nothing has currently been confirmed or finalised.
Next steps and opportunities
This project has been the first where Rift Technologies have worked with an on-road vehicle manufacturer. Rift now need to continue the work towards getting certification for their motor and are currently exploring opportunities to work with other niche OEMs.
