Abstract

In the future, the cost of energy will increase due to environmental problems and limited resources. The electric motors consume a significant amount of electricity in the industrial and in the tertiary sectors of the European Union. Because of its simplicity and robustness the three-phase squirrel-cage induction motor is the prime mover of the modern industry. The electricmotor manufacturers are seeking methods for improving the motor efficiencies, which resulted in a new generation of electric motors that are known as energyefficient motors.

Highlights

  • In the future, the cost of energy will increase due to environmental problems and limited resources

  • Economical Evaluation Generally, energy efficient motors cost an average 15 to 30 percent more than standard motors, but it depends on the specific motor manufacturers and market competition

  • The analysis presented shows that energy efficient motors are an opportunity for improving the efficiency of motor systems, leading to large cost-effective energy savings, improving of the industrial economic efficiency and reducing the environmental impacts

Summary

Introduction

The cost of energy will increase due to environmental problems and limited resources. The electric motors consume a major part of the electric energy in the industry. The induction motor is the main driven system in the modern industrial society. Implementing energy efficient motor could save Europe a significant amount of electricity. It would reduce the production of greenhouse gases and push down the total environmental cost of electricity generation. These motors can reduce maintenance costs and improve operations in industry
