This book presents a comprehensive collection of energy-saving methods for applications using three-phase induction motors. Highlighted techniques include motor power and load matching, speed matching, mechanical properties matching, variable-frequency drives, pole-changing control, and soft characteristic matching. Readers are introduced to the methods of motor reactive power compensation and applications for efficient motors. The authors then analyze the economic operation and energy-saving calculations of three-phase induction motors, before discussing field testing and evaluating methods for motors.
