For motors using liquid lubricated bearing surfaces, shock resistant
capillary seals and lubricating liquid reservoirs are provided. The seals
and reservoirs are formed by the radially opposing disposition of an
inner surface of an outer member and an outer surface of an inner member.
The seals and reservoirs are each oriented with one portion in fluidic
communication with a bearing surface and another portion in fluidic
communication with an opening in fluidic communication with an open air
region of the motor. Grooving is included on at least one of the inner
surface and the outer surface in a portion of the seal or the reservoir
not regularly contacting lubricating liquid. During operation, if
lubricating liquid splashes onto or near the grooving the grooving may
help retain lubricating liquid in the seal and/or reservoir.
