A traditional electric turbocharger (E-turbo) uses a radial flux motor coupled to the turbocharger to provide additional power to the drive the compressor at low speeds. This configuration is not compact and lacks satisfying transient response when motor is powered off because of high inertia of the wheel rotor system. This article proposes a novel E-turbo configuration that uses an axial flux motor and a centrifugal clutch so that the E-turbo is more compact with more flexible connection between motor and wheel rotor system.
