Project Description

Start date: 1st September 2016
Stipend: £18,000 pa and fees paid at Home/EU rates

Project description
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.
