Brushless DC (BLDC) motors which are also named as DC electronically commutated motors, commutatorless motors, DC servomotors or AC synchronous motors are eventually gaining traction over brushed DC motors, and some of the key factors influencing this include high efficiency, extended life, soft torque, and good speed operations. However the applications of these types of motors are still limited by additional cost of motor controller which is one of the key components to operate brushless DC motors. Continuous research and development will result in reduction of these associated costs in coming years. Some of the prominent and successful applications of brushless dc include automotive, HVAC, consumer electronics, healthcare, and other industrial applications include CNC machines, robotics, and actuators among others. Changing trends from brush DC motors to brushless DC motors are due to exceptional operational characters which includes, short index moves, heavy loads, high ...
