Coming soon: 2 lectures, the day will be announced later on.

Thermal aspects in different types of electrical machines,

ass. professor Dr. Luca Papini, University of Pisa, Italy and

Senior Researcher Peter Connor from the University of Nottingham, United Kingdom

The intended learning outcomes:
Students understand the importance of thermal aspects in high-speed electrical machines and drives. Learn to utilize thermal computation methods and seek for multi-disciplinary analyzing methods.

Contents:
State of the art of high-speed electric drives. Introduction to heat transfer. Thermal design theory. Combining thermal and electrical computations. Introduction to multi-disiplinary methods.

Teaching methods:
Pre-assignment, 27 hours. Lectures 5-6.6.2023, computation assignments and homework’s.
Homework's are Students own assessment: thermal modelling computations.
Checking the results day: Results of the assignments (we will agree the day together.)

LUT University persons, please enroll using SISU system.

Homework - info days on 19.6, 28.6 and 10.7 at 10 FINNISH time.

More information from pia.lindh@lut.fi

(1 ECT equals to 27 hours of work and 4 ECT is app 100 hours work)

Homework during the summer is Students own assessment: thermal modelling computations.

Select an electric machine (you can freely select it or use the Comehek-motor article/parameters as attached and you can ask for the FEA-model from Pia)

Computation programs usually have ready-made models, so you can utilize those.

Which program to use?

ANSYS MotorCAD and Altairs Flux2D have tutorials/guidance and models, that you can follow.

Any other program is also fine, or you can make a thermal lumped parameter model with Matlab.

Sharing of the lecture materials didn’t go well, sorry for that, so I will establish a Teams folder, Thermal aspect PhD course-named, for us. You have got an invitation to that. Note, as this is LUT Universities folder, you might need to log to outside group (not your own organization). And you all can discuss over parameters and computation stuff there, if you wish.

Please support each other by discussions in Teams or in your own University as there

are many e.g. from Tampere, TallTech and of course from LUT.

9.6.2023 Pia is in zoom, if you have discussions or questions from 9 to 11 FIN time zone.

Later on, I am in zoom for discussions or returning your Homework on

19.6 at 10, 28.6 at 10 and 10.7 at 12. Finnish time zone again : )

And below are 2 guidelines for thermal network building and utilizing ANSYS MotorCAD provided by Dr. Andrea Credo, University of L'Aquila, Italy
