my research is sensor less speed control of BLDC motor drive, it’s possible to detect ZCD of line voltage. but initial starting speed zero time cont detect ZCD points, if start open loop v/f mean rotor will rotate wrong direction at initial.

any body help me to detect the initial rotor position detection and speed control starting correct direction of sensor less speed control of BLDC motor drive?

if you able pls contact me..

thank you,
