摘要： An electric machine including a stator, a rotor within the stator, and a shaft to which the rotor is mounted. The shaft extends through the stator. A first bearing and a second bearing support the shaft within the stator to allow the shaft and the rotor to rotate within the stator. The rotor is between the first bearing and the second bearing. A first magnetic core is at the shaft between the rotor and the first bearing. The first magnetic core is configured to suppress a bearing current flowing across the shaft, the first bearing, and the second bearing.

摘要： A gyroscopic roll stabilizer for a boat includes an enclosure mounted to a gimbal for rotation about a gimbal axis and configured to maintain a below-ambient pressure, and a flywheel assembly including a flywheel and flywheel shaft, with the flywheel assembly rotatably mounted inside the enclosure for rotation about a flywheel axis. The gyroscopic roll stabilizer also includes a motor operative to rotate the flywheel assembly and disposed inside the enclosure. A motor cooling circuit is configured to transfer heat away from the motor. The motor cooling circuit has a closed fluid pathway for recirculating cooling fluid therein. The fluid pathway includes a fluid channel jointly defined by the motor and the enclosure and having the cooling fluid therein. The gyroscopic roll stabilizer is configured to transfer heat away from the motor to the cooling fluid. Related methods are also disclosed.

摘要： A bearing assembly includes a first bearing unit and a second bearing unit for supporting a shaft, in particular a rotor shaft within a centrifugal compressor in which an axial load acts on the shaft in a first or a second axial direction, the second axial direction being opposite to the first axial direction. When the axial load acts in the first axial direction, the first bearing unit is configured to support both an axial load and a radial load and the second bearing unit is configured to support a radial load. Alternatively, when the axial load acts in the second axial direction, the first bearing unit is configured to support a radial load and the second bearing unit is configured to support both an axial load and a radial load.

摘要： A wheel bearing apparatus includes an outer ring, an inner shaft member, rolling elements, a cage, and a sealing device. The sealing device includes an annular slinger and a sealing member. The slinger has a first inclined surface provided on a radially outer side and on a side facing the sealing member such that a diameter of the first inclined surface increases toward a first side in an axial direction. The sealing member has a second inclined surface provided on the radially outer side and on a side facing the slinger such that a diameter of the second inclined surface increases toward a second side in the axial direction. The second inclined surface intersects with a virtual extension surface extending radially outwardly along the first inclined surface, and the second inclined surface is continuous with an inner peripheral surface of the radially outer portion.
