BLDC Machines

BLDC Machines comprehensively reviews the governing principles and operational implementation of this popular drive system, particularly focusing on rotor design and control system implementation in DSP and FPGA. The book exhaustively reviews the structure, principles of operation and the mathematical modeling of BLDC motors. It reviews current methods to connect windings, including star, delta and open-end winding, and discusses the relevant control methods involved. For each winding connection, their influence on the engine's properties is discussed in-depth. Thereafter, methods of detection points of commutation are discussed for both sensor and sensorless motors. Finally, the problem of rotational speed estimation and methods of implementing a closed control system are evaluated.
