Objetivos

This curricular unit allows the development of technical and scientific skills in the area of electric traction of road vehicles.
Relate and describe the constitution and principle of operation of the electric machines used in electric road vehicles: induction machine and permanent magnet synchronous machine.
Competences will be developed in the interpretation of the energy diagram of the machine, starting, braking and speed control.
Carrying out work in group for to sensitize the students to the aspects related to the organization of the workspace and the safety in the manipulation of this type of equipment.

Obtenção de frequência

The teaching of this course is divided into two kinds of classes: theoretical-practical and practical (laboratorial).
Theoretica l- practical classes:
- Exposition of theoretical subjects, performed with the combination of the expository method and the interpretive method, appealing to the students' participation. Solving application problems in which the active participation of students is promoted.

Laboratory classes:
- The participatory method is followed, although other active methods are also used, depending on the situation. Carrying out laboratory works with the support of specific guides.

Fórmula de cálculo da classificação final

The final classification will be calculated by:

NF = 0.7 * NE + 0.3 * NL
or
NF = 0.7 * ((NT1 + NT2) / 2) + 0.3 * NL
