摘要： A spindle motor comprises a rotational member supported by bearings for rotation about a rotational axis, a rotational body and a motor rotor mounted on the rotational member for rotation therewith, and a motor stator mounted around the motor rotor. The rotational body has an outer diameter determined so that a windage loss of the rotational body is proportional to the third power of a peripheral velocity of the rotational body and an air gap diameter of the bearings and the diameter of the motor stator are determined so that the air loss of each of the bearings and the motor rotor is proportional to the square of the peripheral velocity of each of the bearings and the motor rotor at a range of constant speed of rotation of the rotational member.

摘要： A spindle motor having a simplified construction with reduced axial and radial deflection while avoiding the half whirl phenomenon includes a motor frame, a rotating shaft supporting a rotor, a stator and stator coil, a permanent magnet opposing the stator, and a liquid dynamic pressure bearing. Magnetic centers of the permanent magnet and stator coil, in the axial direction of the rotating shaft, are substantially matched. The liquid dynamic pressure bearing comprises opposing surfaces of the rotating shaft and the housing. The rotating shaft has a disk-shaped thrust bearing portion disposed in a first portion of a cylindrical hole of the housing, and a radial bearing portion disposed in a second portion of the cylindrical hole. Lubricating oil fills a space between the cylindrical hole and the thrust bearing portion and radial bearing portion, and a presser ring is pressed and fixed into a third portion of the cylindrical hole to seal the bearing. A boss portion of the rotor is fixed to a rotor supporting portion of the rotating shaft so that an inner peripheral surface of the boss portion mates with an outer peripheral surface of the rotor supporting portion. The rotating shaft has three axially-spaced portions, with the disk-shaped thrust bearing portion formed between and having a larger diameter than the other portions. A stage is provided between the thrust bearing portion and the rotor supporting portion to serve as a seat for installation of the boss portion.

摘要： A vane compressor includes a cylinder block, a cylinder chamber having an ellipsoidal inner wall, a rotor whose outer circumferential surface is provided with vane slots formed thereon, a drive source for the rotor, and vanes housed in the vane slots, respectively. The rotor is rotated by the drive source while the vanes are protruded from the vane slots by backpressure generated in backpressure spaces in the vane slots to contact end edges of the vanes with the inner wall of the cylinder chamber. The compressor further comprises a stop mechanism that makes the rotor stopped at a predetermined rotational position where a difference between a total volume of the backpressure spaces when operated and a total volume of the backpressure spaces when stopped becomes minimum. According to the compressor, chattering can be prevented without extra workings on the vanes or the rotor and without providing extra parts.
