This course provides students with an integrated development of methods for modelling, analysing and designing systems comprising electrical and mechanical components. In doing so it intends to emphasise to the students the similarity in behaviour between electrical and mechanical systems. The course aims to give an introduction to both electrical machines, circuit and systems, transformers, and similar mechanical systems like gearbox, vibrating system and principles of dynamics, and thus provide the foundation material for several courses at level 3 .
|Session||Second Sub Session||Credit Points||15 credits (7.5 ECTS credits)|
Introduction to an electrical ? mechanical system, Introduction to phasors and AC circuit theory, Multi-element circuits, Resonance of three element AC circuits, Power factor correction of AC circuits
Basic Electromagnetism, Electrical machines: transformers, basic electro-mechanics, shunt and separately excited DC generators, series and shunt DC motors, stepper motors
Free vibration: Spring-mass-damper system from free body diagram to mathematical representation. Analogue of LCR circuit. Damping coefficient, logarithmic decrement.
Forced vibration: Spring-mass-damper system from free body diagram
to mathematical representation. Analogue of LCR circuit. Frequency response. Dynamic magnifier.
A-level or Advanced Higher physics are alternative pre-requisites
This is the total time spent in lectures, tutorials and other class teaching.
1st Attempt: One written examination of two hours duration (80%), continuous assessment based on the tutorials (10%), continuous assessment based on the laboratory /design exercises (10%).
Resit: One written examination of two hours duration (100%).
Lectures will include PRS multiple choice questions on the material being delivered. Feedback will be given over the course of the lab exercises as to the presentation and content of the submissions.
Marked tutorial submissions by allocated study groups will be returned to the students within one week. Students will assess each other's contribution within these groups. The lab exercise submissions will be discussed in small groups. Marked submissions will be returned to the students promptly. The PRS system provides instant feedback on classroom understanding of content.
