PMSM initial rotor alignment: what is the correct strategy?
I'm a newbie, and this is my first approach to motor control. In particular, I should control a PMSM motor (about 1 hp) using the sensorless FOC system based on a BEMF observer.
I'm in trouble about the initial rotor position and the strategies used for this purpose.
Can anyone explain or indicate documents about how, in practice, to do this initial alignment ?
