Design of Electric Machines Course


Apr 16th 2019 - Apr 18th 2019

Manchester, United Kingdom

Updated 21/03/19

This 2.5 day course draws on the experiences of two world-renowned electrical machines designers, and will introduce you to a topic they both agree will be critical to machine design in the future – harmonic filters.

Emer Prof Tim Miller and Dr John Reeve will lecture on the design of synchronous and induction electrical machines, and Dr Dennis Kampen will discuss passive filters for protecting motors against inverter caused motor failures.

We will also hear some of Tim’s career reminisences with some ‘Tales from the Smoking Motor’.

More detail to follow.


Getting to Manchester is simple from across the UK, and Europe.

Bus and Train

Manchester can easily be reached by bus and train from across the UK.


Manchester sits in the midlands, in the middle of a network of motorways that spread out across the UK.

Parking in Manchester isn’t so easy, but the hotel / venue does have a parking arrangement with a nearby car park.


Fly to Manchester Airport from many domestic and international airports.

From the airport, direct trains will take you to Manchester Picadilly train station, minutes walk from the venue hotel.

Wound-Field and PM Brushless PM Machines, and Induction Machines
by Emer Prof Tim Miller of Retrospeed / University of Glasgow

We cover the fundamental electromagnetic conversion theory of AC machines including key topics of saliency, torque production, field analysis, equivalent circuits, winding theory, and performance characteristics. The scope includes wound-field and permanent-magnet brushless PM machines, and induction machines, and it presents these in a balanced way so that their application characteristics can be clearly understood. A detailed design example is included for an induction motor, starting from a simple specification, and this is later converted to a brushless PM motor to show the differences. Throughout, the design methods are entirely based on the classical theory (most of it surprisingly old), which underlies and supports modern computer-based approaches using numerical analysis. Examples of finite-element analysis are introduced at key points, to show where this can enhance the accuracy and where it is capable of solving problems that cannot be solved by other methods. While the treatment is necessarily compressed, it conveys a considerable level of technical depth and insight, including technical interpretation of several key equations and circuits. The presentation is designed to offer consolidation and deeper insights to experienced designers; but it may also appeal to relative newcomers, especially as there are plenty of indications of “where to go from here”, including references to important sources in the literature.

Passive Filters for Protecting Motors against Inverter Caused Motor Failures
by Dr Dennis Kampen of BLOCK Transformatoren-Elektronik GmbH

There are many ways to change the output voltage of the frequency converter by using passive filters. Different filters and the effect of the filters on the motor are presented. The difference between differential and common mode filters is explained. The effect of motor chokes, dv/dt filters and sine filters on the motor voltage forms and bearing currents is shown.
