Course Brief

Unit Abstract 

Electrical machines can be found in manufacturing, transport, consumer appliances and hospitals. People will come across them every day in their home and at work. They convert energy in three ways: transformers which change the voltage level of an alternating
current; motors which convert electrical energy to mechanical energy; and generators which convert mechanical energy to electrical energy. Transducers and actuators are also energy converters, and can be found in a wide range of industrial and domestic applications.

This unit introduces students to the characteristics and operational parameters of a range of electromagnetic powered machines that are used in a variety of applications. Among the topics included in this unit are: principles underlying the operation and construction of transformers, induction motors, synchronous machines, electromagnetic transducers, actuators, and generators; and operating characteristics of electrical machines such as voltage, current, speed of operation, power rating, electromagnetic interference (EMI) and

On successful completion of this unit students will be able to identify the constructional features and applications of transformers; investigate the starting methods and applications of three-phase induction motors and synchronous machines; investigate the types of generator available in the industry by assessing their practical application; and analyse the operating characteristics of electromagnetic transducers and actuators.


  • This course is offered in 45 hours.
  • BTEC Higher National Diploma (HND) in Engineering (Electrical and Electronic Engineering)

    The main aims of the HND in Engineering (Electrical and Electronic Engineering) are to:

    • Prepare students for a range of technical, professional and management career disciplines in Electrical and Electronic Engineering by providing specialised studies which are directly relevant to individual occupations and professions in which students are currently working or in which they intend to seek employment.
    • Enable students to make an immediate contribution in employment in the Electrical and Electronics sector.
    • Provide students with flexibility, knowledge, skills, understanding and motivation as a basis for progression to graduate and postgraduate studies.
    • Develop a range of skills and techniques, personal qualities and attitudes essential for successful performance in working life.

    Graduates of this HND Programme with a good grade profile will be able to access directly the final year of the University of Greenwich's BEng in Electrical and Electronic Engineering Technology at SBCS, Champs Fleurs campus.
