ABSTRACT:
A turbocharger with a rotary electric machine has a permanent magnet, nonmagnetized metallic member, or surfaces of different light reflectivities fixed upon a rotatable member of the turbocharger, as a detectable means. The detectable means is disposed in a position corresponding to the angular position of magnetic poles of the permanent magnet rotor of the rotary electric machine. A detecting means is disposed in a position coacting with the detectable means for detecting the angular position of magnetic poles of the permanent magnet rotor. A shield means is provided for preventing the detectable means from being adversely affected by magnetic fields, oil, and dust, so that a detected signal of a high S/N raio can be produced for accurately detecting the angular position of the magnetic poles of the permanent magnet rotor as it rotates.
