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 speed, short duty cycle moves, high torque control and high accel or decel capability.
New set of applications include medical use cases, brushless DC motors are used in the treatment of sleep apnea which demands for Positive Airway Pressure (PAP) respirators. IN PAP to drive the blower fan, brushless DC motors are employed. The blower fan generates PAP to assist the patient in breathing while they are asleep. Growing applications and use cases in healthcare will bolster the brushless DC market by 2020. Additionally, the exponential growth in demand for IoT devices, coupled with many industrial devices will help in propelling the global Brushless DC market.Brushless DC market is classified by voltage as follows:
