摘要： An electric machine coupled to rotating machinery includes a rotor and a stator, and the method of control of an electric machine and an electric machine control system. The method includes sensing one or more parameters indicative of one or more resonance conditions of the rotating machinery, and comparing the sensed parameter to a predetermined threshold to determine whether the rotating machinery is operating at the resonance condition. Where the rotating machinery is determined to be operating at the resonance condition, adjusting a magnetic field of one or both of the rotor and the stator to provide a predetermined torque to the rotating machine, to modulate the stiffness of the rotational machinery, and thereby move the resonance condition away from the current rotating machinery conditions.

摘要： A sliding component, which can seal and lubricate at the same time by reducing the amount of leakage of sealed fluid further while preventing torque increase and local wear, is characterized in that an extremely shallow step of circular shape is provided on a sealing face of one of a pair of sliding parts that slide against each other in such a way that the step is positioned on the low-pressure fluid side (atmosphere side) of this sealing face and also set lower than the sealing face, and that pumping grooves acting to push back toward the high-pressure fluid side (sealed fluid side) the fluid that tends to leak from the sealing face toward the low-pressure fluid side (atmosphere side) are provided on the surface of the extremely shallow step.

摘要： A journal bearing (51) has spiral grooves (63, 64) on opposite ends (61, 62) of the journal bearing (51) as to face towards the opposing shaft surface and generate a flow of oil outwardly of the journal bearing (51) during shaft rotation. One bearing end has a clockwise spiral groove (63) which pumps lubricant fluid in a first direction. The opposite bearing end includes a reverse-directed, counterclockwise spiral groove (64) which pumps fluid in a second direction, opposite to the first direction. During clockwise rotation of the shaft (21), the lubricating oil flows in the first and second directions to lubricate the turbine and compressor sides of a turbocharger. The journal bearing (51) also may be flipped endwise so as to function during opposite, counterclockwise shaft rotation.

摘要： A fluid dynamic bearing (FDB) includes a groove configuration that includes a pressure-generating groove pattern, and additionally includes a circumferential groove adjacent to the pressure-generating groove pattern and a pumping groove pattern adjacent to the circumferential groove. The circumferential groove may be deeper than the associated pumping and pressure-generating groove patterns and may extend for 360 degrees, and the pumping groove may be positioned at or near the entry to the bearing journal area to help maintain fluid flow direction and minimum pressure. Such an FDB groove configuration is likely to provide improved damping characteristics while maintaining relative stiffness, thereby improving vibration response characteristics.

摘要： An inner peripheral surface and a lower end surface of a bearing sleeve made of a sintered metal are each formed into a smooth cylindrical surface or a flat surface that does not have a dynamic pressure generating portion. Thus, a step of forming the dynamic pressure generating portion can be omitted from a manufacturing step of the bearing sleeve, and cost of dies can be markedly reduced. Further, the inner peripheral surface of the bearing sleeve is formed into the smooth cylindrical surface, and hence a radial dynamic pressure generating portion is formed on an outer peripheral surface of a shaft member. However, the outer peripheral surface of the shaft portion is accessible to tools, and hence the radial dynamic pressure generating portion can be formed easily with high accuracy. As a result, accuracy of a radial bearing gap is enhanced so that a bearing rigidity is enhanced.
摘要翻译：由烧结金属制成的轴承套的内周面和下端面分别形成为没有动压产生部的光滑圆柱面或平面。因此，可以从轴承套筒的制造步骤中省略形成动压产生部的步骤，并且可以显着降低模具的成本。此外，轴承套筒的内周面形成为平滑的圆筒形表面，因此在轴构件的外周面上形成径向动压产生部。然而，轴部的外周面能够被工具接近，因此能够容易地高精度地形成径向动压产生部。结果，径向轴承间隙的精度提高，从而提高了轴承刚度。
