ABSTRACT:
An improved machine includes a combination of elements of a rotary electric machine and an air compressor, such as in a turbocharger, and provides an improved turbocharging device for enhancing turbocharged internal combustion engine performance. The improved turbocharger includes a plurality of magnets which are mounted in a generally circumferential arrangement about the back face of the compressor wheel. A stator winding is mounted in opposing relation to the motor magnets. Torque can be applied to the magnets and hence to the compressor wheel when the stator is energized by an appropriate energizing circuit, thereby improving engine performance especially at low engine speeds.
