SYSTEMS AND METHODS FOR SECURING A ROTOR APPARATUS |
| 摘要 |
Rotors apparatus usable in energy storage devices and power systems include a plurality of laminations having a center and at least one orifice spaced a distance from the center, and at least one fastener extending through the orifice. The one or more fasteners, the one or more orifices, or combinations thereof are sized to reduce contact between the fasteners and the laminations during rotation of the rotor apparatus. The fasteners and orifices can define an envelope, corresponding to the maximum space able to be occupied by a fastener to reduce contact between the fastener and the laminations, and one or more fasteners can have a volume of material less than the volume of the envelope to reduce bending forces on the fastener. |
