Abstract :
Sensorless Brushless DC motors have been a research focus home and abroad, because their characteristics of small volume, high reliability, strong anti-interference and the ability to overcome inaccurate commutation caused by mechanical installation. This article will carry on a research on the operation principles and performance characteristics of sensorless DC motors and methods that terminal voltage of sensorless brushless DC motors detects rotor position.
