A motor assisted turbocharger comprised of a compressor rotor and a motor drive on separate aligned bearing axes, and a torque transmitting slip coupling therebetween devoid of mechanical interengagement and driving the compressor on demand, and an engine exhaust driven turbine rotor coupled to the compressor rotor with an averrunning clutch which separates the compressor mass from the turbine mass for maximized acceleration of the compressor rotor and turbine rotor by disengagemnt of the turbine rotor from the compressor rotor, and with an inertia responsive mechanism to engage and disengage said torque transmitting slip coupling.

[ I claim:] [1.]1. A motor assisted turbocharger for employing residual exhaust engery from and to increase air induction pressure into internal combustion engines, and including;a compressor rotor and a turbine rotor on a first bearing means for rotation on a fixed axis,a motor drive on a second bearing means for rotation on a fixed axis separate from and aligned with said first axis,the first bearing means having greater radial clearance that the second bearing means whereby the combined rotar mass seeks a floating axis of rotation distinct from the axis of the second bearing means,and a coupling means between the motor drive and the compressor rotor for transmitting torque therebetween devoid of mechanical interengagement and comprised of a drive member fixed to the motor drive and spaced from a drive member fixed to the compressor rotor a distance greater than radial displacement of said floating axis.
