ELECTRICAL ENGINEERING, BASIC COURSE

MIE012

Credits: 9. Grading scale: TH. Cycle: G2 (First Cycle). Main field: Technology. Language of instruction: The course will be given in Swedish. MIE012 overlaps following cours/es: MIE011 and MIE030. Compulsory for: M3, MD3. Course coordinator: Assistant Lecturer Bengt Simonsson, Bengt.Simonsson@iea.lth.se, Industrial Electrical Engineering and Automation. Recommended prerequisits: FMAA01 One Dimensional Analysis, FAF260 Physics, basic course, EDA501 Programming, basic course. Assessment: Passed laboratory work including preparatory tests and two written partial exams. Material from the first partial exam might occur also in the second one. The grade for the course is based on the weighted mean of theresult of the two partial exams. If the partial exams are not passed, there will be one written exam for the whole course. Parts: 2.

Aim
Mechanical engineers need to use more electronics today than ever before. Most products, processes, and systems involve one or more of the following items:

measurement of electrical and non-electrical variables;
signal processing;
analogue and digital, power electronic and electromechanical energy conversion.

To be able to structure and use such technology, the engineer needs basic knowledge of electronics. The aim of this course is to give a broad knowledge of the wide field from Ohms law to computer-based control of servo motors.

Knowledge and understanding
For a passing grade the student must

be able to account for the theory of DC and AC circuits
have basic knowledge in applied electronics, both analogue and digital
have basic knowledge in electric measurement, sensors and how signals are amplified and filtered
have basic knowledge in how electric machines in industrial drive systems work and are controlled
have basic knowledge in Boolean algebra, digital combinatorial networks, the structure of the micro computer and basics for its programming
have basic knowledge in programming of a PLC-system (industrial programmable digital control systems).

Skills and abilities
For a passing grade the student must

be able to analyse basic DC and AC circuits
be able to suggest and analyse basic circuits in signal electronics, e.g. suggest a circuit for interfacing a sensor signal to its control computer
be able to elect a suitable industrial drive system for a given application
be able to perform basic automation control using a PLC-system.

Contents
