UA31 Features and Applications of Electrical Machines
Pearson BTEC Level 3 Engineering – UA31 Features and Applications of Electrical Machines
This unit can be studied as a standalone TECOL unit in Engineering, or as part of an Edexcel accredited BTEC Level 3 qualification in Engineering.
Aim and purpose
This unit aims to give you the knowledge and an understanding of the features and applications of a range of electrical machines (motors, generators and transformers) and the hazards, legislation and regulations related to working with electrical apparatus
All electrical machines use applications of electro-magnetic principles where electric currents create magnetic fields, which either attract or repel each other. This is the basis of all DC and AC electric motors and generators. Transformers are devices that also use the principle of electromagnetism. These are generally very efficient and their output power can be almost 100 per cent of the input power, depending on the application.
Further, this unit has been designed to help you understand the complexities of electromagnetism and its applications to everyday electrical devices, systems and apparatus. Learners will consider a range of machines, their application and their control. In addition, the unit will help learners understand relevant electrical hazards, legislation, regulation and standards.
On completion of this unit you should:
1 Know the electrical hazards and the legislation, regulations and standards related to working with electrical apparatus
2 Understand alternating current (AC) machines
3 Understand direct current (DC) machines
4 Know how electrical machine control circuits and systems operate.
This unit will give you an opportunity to examine a range of electrical machines, their design, control and application.
