Proceedings of the 19th Electrical Electronics Insulation Conference, 2003
The author discusses those factors which determine the efficiency and rating of polyphase AC induction motors. The loss mechanisms are described and are related to the performance and design characteristics of the motor, such as the operating flux density, the winding turns distribution, the current density in the windings, the motor speed torque ...

Energy Efficiency in Electric Motors
2021Electric motors are electrical machines that convert electrical energy into mechanical energy to perform useful work. In general, electric motors have three main parts: a rotor, a stator, and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually so long as it receives a steady

1997
The need for energy conservation in North America has accelerated the requirement for increased levels of electric motor efficiency. Various studies as the A.D. Little Report, sponsored by the Federal Energy Administration, indicate that approximately two thirds of all generated A.C. power is used to drive electric motors.

Assessment of Nonintrusive Motor Efficiency Estimators
IEEE Transactions on Industry Applications, 2004Three instruments have been evaluated for their ability to estimate the load conditions and efficiency of operating motors based solely on measurements of terminal voltage and current. Laboratory tests, compared to a high accuracy dynamometer system were used to assess the instruments' accuracy.

Energy Efficient Motor Technologies
1997Electric motors consume over half of all electricity used in developed countries and typically 60–80% of the electricity which is used in the industrial sector. The use of energy-efficient motor technologies can produce substantial electricity savings which are also normally associated with process improvements and longer life of the motor drive ...

Induction Motor Efficiency Measurement
2000There can be no doubt that the most accurate methods for determining the efficiency of an induction motor are based on calorimetry. Such methods seek to determine losses directly be measuring the heat generated by the appropriately loaded motor. Unfortunately, however, calorimetric testing is expensive and time consuming and as such is completely ...
