BLDC Motor Drive Simulation and Control

: Electric motors is necessary for all most of all practical systems and becoming integral part in everybody life of modern living. It is hard to imagine that there are more than 700million electric motor drive systems of various sizes are operational throughout the world. In the last few years conditions have been changed in adjustable speed drives due to wide spread use of power semiconductor devices with available ratings up to 6000V and 3000A without even connecting series or paralleling the devices. The present competitive development in the solid state devices, control systems and signal processing all over the world result in significant progress in performance of AC drives and decreasing the overall drive cost. In order to meet different practical applications, various types of motors such as synchronous motors, induction motors, DC motors, switched reluctance motors, from several millwatts to millions of kilowatts. The Permanent Magnet Brushless DC (BLDC) motors have been emerged in wide areas of real world applications due to their higher power density, good dynamic performance and ease of control. Further, the motor has high efficiency over a good speed range. In this book simulation of BLDC motor drive and its control is elaborately discussed and is useful for students and faculty members to understand the simulation and control aspect of BLDC motor drive.
