摘要： A motor rotor structure for an electric turbo charger is manufactured at low cost with good quality by fixedly fitting, over a shaft, a rotor core having electromagnetic steel sheets pre-formed as an integrated stack. The rotor structure includes a rotor core which is rotated by a magnetic field formed by a stator in a housing; a shaft configured to rotate a compressor impeller and the rotor core together; and a bearing supporting the shaft. The rotor includes the rotor core including the electromagnetic steel sheets; a stopper portion formed at an intermediate portion of the shaft to restrict axial movement of the rotor core; and a pressing unit which presses the rotor core fitted over the shaft against the stopper portion. The pressing unit prevents a circumferential phase shift between the shaft and the rotor core by a pressing force thereof.

摘要： A structure of a radial turbine scroll avoids a gas flow heading from a radially outer side toward a radially inner side in the vicinity of a tongue portion so as to restrain turbine performance from deteriorating and also reduces, to a maximum, thermal stress caused by the formation of the tongue portion. In the structure of a radial turbine scroll, an operating gas is led to flow in the radial direction from a spiral scroll formed in a turbine casing into turbine moving blades of a turbine rotor, which is positioned on the inner side of the scroll, so as to act on the turbine moving blades, and then led to flow outside in an axial direction, thereby rotatively driving the turbine rotor, wherein the scroll 4 has a partition plate 20 formed to have a length of a certain range on a line of a tongue portion formed on the inner periphery of a gas inlet portion or has a reduced height between scroll side walls at an outlet portion of a tongue portion 21 formed on the inner periphery of a gas inlet portion of the scroll, thereby avoiding a gas flow heading from the radially outer side to the radially inner side in the vicinity of the tongue portion.
