This paper presents the technological advancements of embedded sensors and microprocessors into AC induction motors and their ability to predict failure. Today, maintenance departments utilize several stand-alone technologies to detect and predict motor failure such as vibration and flux analysis. Intelligent motors now integrate multiple technologies that enable continuous monitoring of critical motor components as well as operating conditions. In today's global economy, the need to increase profitability while decreasing operating expenses sets the stage for the emergence of intelligent motors.
