IL1390 Sensors and Actuators 6.0 credits

The study of the working principles and the property of:

Sensors (analog and digital) for measuring of position, force, displacement and other mechanical entities and temperature.

Electrical motors and motordrives.

The need to sense or measure quantities of different types has increased dramatically during the past years.
This depends on that nowdays one strive to replace pure mechanical products with a combination of mechanical and electronic engineering, mechatronics.
In industrial automation classical transducers and sensors are used, while in mechatronical design simple sensor elements are integrated with electronics and processor to form a cost benefit solution.Sensors play a key role in mechatronics and industrial automation.

In industrial automation one use the classical electrical motors as actuators. In the mechatronic products you often find completly newmotortypes where sensors, processor and drive electronics combines to a unit.

The need to understand the working principles of electrical motors and their parts has hence increased.

The student should after the course:

• Have knowledge about of the working principles and architecture of a large number of sensors and their elements.
• Be able to chose and use sensors and equipment for measuring mechanical quantities and temperture.
• Have knowledge about the architecture and working principles of the most common electrical motortypes.
• Be able to chose and use electrical drives and actuators.
• Be able to cooperate in a active way with specialists in theese areas.

Basic knowledge of electric circuits.

If the course is discontinued, students may request to be examined during the following two academic years.

• ANN1 - Assignment, 1.5 credits, grading scale: A, B, C, D, E, FX, F
• LAB1 - Laboratory Work, 1.5 credits, grading scale: A, B, C, D, E, FX, F
• TEN1 - Examination, 3.0 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Passed laboratory course 1,5 hp (LAB1).
Passed exam 3 hp (TEN1) .
Individualised questions to solve during the course 1,5 hp (ANN1).

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

The course is evaluated and developed according to the KTH policy for Course Analysis (see KTH-Handbok 2, Tab 14.1)
