This unit introduces the analytical and numerical techniques that are used in the electromagnetic and thermal design of modern high performance AC machines, in particular focussing on the design of AC induction motors and brushless AC permanent magnet machines. The unit builds on previous Yr 2 and Yr3 electromechanical energy conversion courses (EENG 27000 and EENG 37000). A second unit EENGM7041 Electrical Drives explores the control of AC machines.
Material characteristics: Be able to describe the characteristics and specifications of soft magnetic and permanent magnet materials and apprise the critical material properties used within the design process Electromagnetic design – analytical methods: Apply analytical techniques based on fundamental magnetic field theory to the design of AC windings and the calculation of key design parameters; inductance, emf, etc. (Assessed by exam element) Electromagnetic design –numerical methods: Be able to describe the basic principles of finite element electromagnetic field analyses and apply the techniques to the design of an electrical machine. Evaluate post processing techniques applied to finite element field solutions. (Assessed by coursework element) Thermal analysis: Apply lumped parameter thermal networks to analyse the temperature distribution in electrical machines. Examine how losses and their distribution are determined from magnetic field solutions and the motor operating point. (Assessed by exam element) Design process: Be able to apply the electromagnetic design process used in the design of electrical machines through a case study. (Assessed by exam element)
