Abstract:
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.
