Abstract :
Induction motor efficiency can be significantly improved (specially under light loads) by reducing the motor air-gap flux. Flux can be indirectly controlled by adjusting both stator voltage and frequency. This paper describes the development and implementation of a controller for a voltage source inverter fed induction motor with online efficiency optimization. The system was tested for a small power induction motor and results are presented
