Introductory description

Electrical machines and drives are the core enabling technology which allows conversion between electrical and mechanical energy. This module considers the operation of a variety of electrical machines (such as synchronous, induction, dc and reluctance machines) and their control.

Interdisciplinary

Employs systems (control) and electrical engineering knowledge to consider electromechanical systems.

Subject specific skills

Communicate technical information with others at all levels, including technical reports and the use of digital tools.
Follow a methodical approach to engineering problem solving.
Establish and report engineering design briefs.
Select the design solution for a given electro-mechanical engineering application and environment using data to inform their decisions.
Use appropriate equipment to develop and execute test plans to support electro-mechanical product validation and approval.
Write and document structured programming code for electro-mechanical systems.
Assemble, wire, program and test electrical equipment, motors and control systems.
Communicate effectively on complex engineering matters with technical and non-technical audiences.

Transferable skills

Hold paramount the health and safety of themselves and others, and model health and safety conscious behaviour.
Self-motivated, work independently and take responsibility for their actions. Set themselves challenging personal targets and make own decisions.
Communicate confidently to create and maintain working relationships. Be respectful.
Prioritise quality. Follow rules, procedures and principles in ensuring work completed is fit for purpose, and pay attention to detail / error checks throughout activities.
Adjust to different conditions, technologies, situations and environments and to new and emerging technologies.
Exercise responsibilities in an ethical manner, with openness, fairness and honesty.
Commit to personal learning and professional development.
