Abstract
Induction motors consume over half of the electric energy produced. Much of it is wasted because efficiency drops when induction motors are not fully loaded. Typically, motors are oversized to meet peak load demands and are inefficient for lesser loads. This paper describes a system for dynamically matching the motor to the load by increasing stator turns for light loads. This decreases stator current and power absorbed from the power line. Stator turns are adjusted in half cycle increments. This results in a wide range of possible average adjustments and quick response. Dynamic power control increases efficiency and improves power factor.
