Summary of Content

The aim of this module is to provide the student with a detailed understanding of the Electrical Systemcomponents design such as transformer, generator, and motor etc.

Syllabus

The teaching syllabus will cover the following areas: -360b7 Windings: Types. Pitch and distribution factors, harmonics, tangential and radial field components, emf, applications, winding analysis and design. b7 Construction of single phase and three phase transformer connection and Construction, Shell type and core type transformer, Cross sectional view, Cooling of Transformer. b7 Permanent Magnets: Types, characteristics, sensitivity to temperature and demagnetizing fields, energy product, load line approach, manufacture, application and selection. b7 Induction Machine: Steady-state models, transient models (d-q axis, rotor reference frame and transformation), application to drives, dynamic operation and unbalanced conditions. b7 Switch Reluctance: Construction and characteristics, idealized model (zero resistance, linear inductance), non-idealized model, torque/angle and flux/current characteristics, dynamic performance, control strategies and drive systems, application of ECAD. DC Brushless: Construction and characteristics, transient and steady state models, computer-aided solutions, typical applications

Learning Outcomes

On completion of this module the student should be able to:1. Explain the general considerations, type of windings and connections used in electrical machines and transformers (AM1,AM3,AM5)2. Outline the characteristics and applications of the switch reluctance motor and the PM machines (including BLDC) (AM1)3. Develop an outline winding design for a rotating machine and HV transformer given an application specification (AM1,AM6,AM7)4. Evaluate the performance of an electrical power system component using appropriate computer aided simulation (AM1)

Teaching / Learning Strategy

The main teaching method will be based on lectures. The students will be expected to perform directed reading exercises and self-learning exercises on topics related to Electrical Machines Design. Tutorials will be used to reinforce the module material and to discuss the issues raised by the directed reading
