Ricardo has been working on the concepts for a low-cost, low-weight, synchronous reluctance electric motor for a hybrid vehicle. There are many benefits in terms of weight, space, and costs savings, but there are also significant technical challenges including:
• A reluctance rotor for high speeds (>40k rpm).
• Bearings that will function at high temperature and high speed.
• Efficient stator design.
• An effective manufacturing route for low cost.
The EngD student will work closely with a student working on the design of the rotor from the electrical machines and drives group, and a second student working on bearing design and high temperature lubrication from the tribology CDT, both in the Faculty of Engineering at the University of Sheffield.
The student will develop manufacturing and machining methods for affordable rotor bearing and shaft manufacture. This will be achieved by working closely with colleagues on material choice and design requirements, and undertaking a trade study underpinned by validated process models for optimum process and parameter selection. A demonstrator motor will be produced by the three students.
Innovative manufacturing techniqiues will be required to achieve the design requirements at the target unit cost for the automotive sector. The student will explore the machinability and a range of manufacturing techniques for proposed materials, creating process models for the material processing. These physics-based models will be validated experimentally.
A tool will be created to support design engineers on material selection and manufacturing method and parameters with respect to cost, quality and performance of the rotor and bearings and overall unit.

All applications should be submitted online. See the How to Apply section of the IDC website. Please follow the instructions carefully, and ensure that you specify which project you are applying for. Your supporting statement should include why you are interested in the project theme, and why you are a good candidate for the project.
Applicants must have, or expect to get, a 1st or good 2:1 degree (or Masters with Merit) in a relevant science or engineering subject such as mechanical engineering, materials science or physics.
Due to EPSRC residency requirements, this project is open only to UK and EU applicants who have been resident in the UK for at least 3 years immediately preceding the start of the course.
All applicants require an English language qualification, typically a GCSE or an IELTS test (a score of 7 or above is required, with a minimum of 6 in each component).
