Motor

A motor comprising:

• a rotary portion comprising a shaft having a center on a vertically extending central axis;
• and
• a stationary portion comprising a stator and a bearing portion rotatably supporting the shaft, wherein
• the bearing portion comprises:
• a sleeve bearing radially outward of the shaft, wherein the sleeve bearing contains a lubricating oil;
• and
• a housing that radially outward of the sleeve bearing,
• the stator comprises:
• a stator core radially outward of the housing;
• and
• an insulator that covers at least part of the stator core,
• a first member attached to the shaft, wherein the first member axially displaced from the sleeve bearing in a first direction, and the first member extends radially outward from an outer peripheral surface of the shaft,
• a second member attached to the housing, wherein the second member is axially displaced from the sleeve bearing in the first direction, the second member is axially displaced from the first member in a second direction opposite the first direction, the second member extends radially inward from an inner peripheral surface of the housing, and the second member and the first member define a gap therebetween, and
• the second member comprises:
• a first hole, wherein the shaft extends through the first hole;
• at least one second hole radially outward of the first hole, wherein each of the at least one second hole penetrates through the second member.
