Controlling an electronically-assisted turbocharger

A first line-to-line terminal voltage of a three-phase electric motor is measured while the three-phase electric motor free-spins. A second line-to-line terminal voltage of a three-phase electric motor is measured while the three-phase electric motor free-spins. A motor's rotor position is dete...

Beschreibung
Zusammenfassung:	A first line-to-line terminal voltage of a three-phase electric motor is measured while the three-phase electric motor free-spins. A second line-to-line terminal voltage of a three-phase electric motor is measured while the three-phase electric motor free-spins. A motor's rotor position is determined based on the first line-to-line terminal voltage and the second line-to-line terminal voltage. Three-phase current is sent to the motor after the rotor position has been determined. The three-phase current being in-phase with the rotor position.
