Electrical Machines

Herefordshire, Ludlow & North Shropshire College

Progression and benefits

On successful completion of this unit, you 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 and analyse the operating characteristics of electromagnetic transducers and actuators.

About the course

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 you 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 efficiency
