Introduction:
This manual gives a brief description of state-of-the-art technologies used to develop high efficiency motors, including premium efficiency induction motors, permanent magnet motors, and switched reluctance motors.
It also analyses issues that affect motor system efficiency and provides guidelines on how to deal with those issues namely by:
 Selection of energy‐efficient motors
 Properly sizing of motors;
 Using Variable Speed Drives (VSDs), where appropriate. The use of VSDs can
lead to better process control, less wear in the mechanical equipment, less
acoustical noise, and significant energy savings;
 Optimisation of the complete system, including, the distribution network,
power quality and efficient transmissions;
 Motor Systems Energy Assessments
 Taking Measurements
 Applying best maintenance practices.
 Motor Repair
 How to win approval for energy efficiency projects
 Energy Management Systems
