The power density, fast response, lower maintenance, better longevity and accuracy have allowed brushless direct current (BLDC) motors to be used in various fields such as automotive, health, consumer electronics. Most application of BLDC motor such as ventilator, respirators, DVD drives motor, drone, robots, radio-controlled toys, HVAC are low powered and mandate less noise and high efficiency. Low-power motors, controller cost and size are critical considerations, necessitating the adoption of a simple yet reliable control strategies. Low power motors do not have an inbuilt sensor to sense the rotor position, so other schemes without the rotor positional feedback are used to control them. Sensorless motor control scheme comes with a trade-off, i.e. commutation error brings up the problem of start up issue, torque ripple, acoustic noise, and reduced efficiency. The way these problems are mitigated are reviewed in this paper. This paper reviews the methods of sensorless BLDC motor control and also reviews the available commercial options to control the BLDC motor. Application-specific Integrated Circuits (ASICs) are the most viable and cost-effective solution for commercial market. ASICs such as LV8961, DRV10983 are discussed with their method of sensorless control.
