Abstract

A motor frame is disclosed. According to an exemplary embodiment in the present disclosure, a motor frame includes a main frame including a component of a motor provided therein; and a front cover and a rear cover covering an open front surface and an open rear surface of the main frame, respectively, and having cores into which the component of the motor is inserted, respectively, in which a region between the main frame and the cores is asymmetrical in a vertical direction.

First claim

What is claimed is:

1. A motor frame comprising:
a main frame including a component of a motor provided therein; and
a front cover and a rear cover covering an open front surface and an open rear surface of the main frame, respectively, and having cores into which the component of the motor is inserted, respectively,
wherein a region between the main frame and the cores is asymmetrical in a vertical direction,
wherein the main frame includes a plurality of frame formation portions being portions of a cylinder, having different respective radii of curvature, and coupled to each other, or centers of the cores are positioned below a center of the main frame that is cylindrical,
wherein portions of the front cover and the rear cover, between the main frame and the cores are provided within a cooling tube provided in a space between the main frame and the cores,
wherein a space between the main frame and the component of the motor has a passage space through which a cable connected to the component of the motor passes,
wherein the passage space is partitioned by a blocking member in such a manner that air heated by heat generated by operations of the component of the motor does not flow in the passage space, and
wherein the main frame includes a frame member and the blocking member partitions the passage space along with the frame member.

2. The motor frame of claim 1 , wherein the main frame includes a first frame formation portion and a second frame formation portion coupled to each other.

3. The motor frame of claim 2 , wherein the second frame formation portion forms a lower portion of the main frame, and the first frame formation portion forms the remainder of the main frame.

4. The motor frame of claim 3 , wherein a radius of curvature of the second frame formation portion is greater than a radius of curvature of the first frame formation portion.

5. The motor frame of claim 4 , wherein the second frame formation portion is a flat plate.

6. The motor frame of claim 1 , wherein the cores are cylindrical.

7. The motor frame of claim 6 , wherein a radius of each of the cores is smaller than the radius of curvature of each of the plurality of the frame formation portions having the different respective radii of curvature and coupled to each other to form the main frame, or smaller than a radius of the main frame that is cylindrical.

8. The motor frame of claim 1 , wherein the front cover and the rear cover have an insertion hole which the cooling tube is inserted into or connected to.

9. The motor frame of claim 1 , wherein the cooling tube is provided as a plurality of cooling tubes, and an arrangement height of the plurality of cooling tubes provided in lower portions of a space between the main frame and the cores is lower than an arrangement height of the plurality of cooling tubes provided in upper portions of the space between the main frame and the cores.
