Module Overview

An introduction to the analysis and design of power transmission for electro-mechanical systems.  Hybrid-electric drive is an emerging technology for automobiles, and comprises an interesting blend of mechanical and electric power transmission.  This module establishes the foundation necessary for comprehending electro-mechanical power transmission technologies, and also includes an overview of hydraulic and pneumatic systems.

Module Aims

To give an overview of the concepts of power generation, distribution and use in mechanical engineering systems with particular reference to electric drives and hybrid car technology.

Learning Outcomes

At the end of the course, the student should be able to:


·      Identify and analyse the components of electrical power transmission systems (with particular reference to electric and hybrid car technology);


·      Describe the characteristics of the most common DC and AC motors, and perform basic numerical analysis for the determination of dynamic behaviour and power transfer and efficiency;


·      Describe the operating principles of Internal Combustion Engines, and perform basic numerical analysis in terms of performance;


·      Make a technical evaluation of hybrid-electric vehicle powertrains;

  • Identify the key components of, and analyse the performance of hydraulic and pneumatic power systems.
