A sensorless initial rotor position's estimation for permanent magnet synchronous machines [PDF]

open access: yes, 2015
Permanent magnet synchronous motors for the effective start require information about the initial position of a rotor. In this regard, most systems use position sensors, which substantially increase entirely a cost of an electrical drive [1-3].
