Abstract
Systems and methods include a channel (114) through an upper endshield (50) that directs an air stream to cool bearings (30), lubricant, and electrical originated heat.
Claims20
A motor comprising:
- a stator frame housing a rotor and a stator in an electrical components housing space;
- an endshield at least partially covering an open end of the stator frame and housing bearing in a bearing housing space;
- a fan cover guard housing a fan, wherein the endshield is positioned between the stator frame and the fan cover guard;
- a shaft to which each of the rotor and the bearing is connected, wherein the shaft defines a longitudinal axis;
- a channel that is configured to direct an air stream that moves in a downstrear direction, wherein the channel is configured to direct the air stream:
- through the endshield;
- and
- from an upstream end of the channel radially inward toward the bearing.
5 more elements
An endshield, comprising:
- a first end configured to at least partially cover an open end of a stator frame, wherein the stator frame is configured to house a rotor and a stator;
- a bearing housing space configured to house a bearing that is attached to a shaft, wherein the shaft defines a longitudinal axis;
- a second end configured to attach to a fan cover guard, wherein he fan cover guard is configured to house a fan;
- a channel that is configured to direct air stream from the second end to the first end, wherein the air stream moves in a downstream direction from the second end to the first end;
- and
- an oil reservoir, wherein the channel separates:
- the bearing housing, space from the oil reservoir;
- and
- the oil reservoir from the first end.
