PMSM motors are becoming popular in the industrial design of white good appliances. Anyway, their control has to take account one the most peculiar aspect that regards the design of electronic control systems: the thermal management. In this book, the design of control systems for electrical drives is presented, the concepts regarding the static and dynamic thermal characteristics of intelligent power modules (IPMs), commonly used in PMSM control, are examined and the thermal design for heat dissipation in IPMs is illustrated.
