Electrical Engineering

But du cours

The objective of this course is to learn how to size, model, and analyze magnetic circuits (applied to coils, electromagnets, and transformers) as well as electromechanical conversions (DC machines and AC machines).

Acquis d'apprentissage visés

• To have general knowledge of electromechanical converters (rotating machines).

• To know the basic properties of the three types of motors: direct-current motor, alternating-current motor, and stepper motor.

• To be able to identify which electrical quantity (voltage $U$, current $I$, or frequency $f$) affects which mechanical quantity (torque $T$ or rotational speed $\Omega$).

• To understand the concepts of active and reactive power.
