<p>An electrically assisted turbocharger (10) includes an electric motor (70) having a rotor (72) and a stator (74). The rotor (72) rotates in response to operation of the turbocharger (10) and the stator (74) is fixed relative to the rotor (72). A component (40, 48, 24) rotates in unison with the rotor (72) and includes a plurality of features (80, 84, 86, 90). To control timing of phase excitation of the electric motor (70), a position sensor (82) is mounted to the turbocharger (10) to detect the plurality of features (80, 84, 86, 90) on the rotating component (40, 48, 24) to determine a rotational position of the rotor (72).</p> |
