Abstract :
The purpose of this study is to update users on the opportunities available to achieve higher levels of motor efficiency and to summarize the government and industry activities that are driving these higher levels. The impact of adjustable frequency drives is included. A summary forecasting the future required levels and the method of demonstrating compliances is provided. The relationship and tradeoffs between efficiency and power factor are addressed
