Definitions
- the present invention relates to a rotating electrical machine used in, for example, a motor of an elevator hoisting machine.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2005-117821
- the present invention has been made to solve the above-described problems, and provides a stator for a rotating electrical machine capable of further increasing the coil space factor while preventing interference between coils. With the goal.
- a stator of a rotating electrical machine includes an iron core having an annular core back portion and a plurality of teeth portions projecting radially inward from the core back portion, and a coil conductor is aligned and wound around the teeth portions.
- a coil group is formed by winding, and the coil group is divided into a plurality of coil segments adjacent to each other in the circumferential direction of the iron core, and each coil segment is a plurality of coils adjacent to each other in the circumferential direction of the iron core.
- Each stepped coil has a large-diameter portion adjacent to the core back portion, and a small-diameter portion adjacent to the large-diameter portion on the radially inner side of the iron core and having a smaller diameter than the large-diameter portion, A step portion is formed between each large-diameter portion and each small-diameter portion due to the difference in diameter between them, and the position of the step portion in each coil segment is located around the periphery of the iron core. Stepped coil force located at one end in the direction is shifted inward in the radial direction of the iron core.
- FIG. 1 is a cross-sectional view of a stator of a rotating electrical machine according to Embodiment 1 of the present invention.
- FIG. 2 is an enlarged view of the main part of FIG.
- FIG. 3 is an explanatory view showing a winding method of each coil in FIG. 1.
- FIG. 1 is a cross-sectional view of a stator of a rotating electrical machine according to Embodiment 1 of the present invention
- FIG. 2 is an enlarged view of a main part of FIG.
- the iron core 1 has an annular core back portion 2 and a plurality (16 pieces in FIG. 1) of teeth portions 3 in which two core back portions protrude inward in the radial direction.
- a coil group (concentrated wire group) 4 is provided inside the iron core 1.
- the coil group 4 is formed by winding a coil conductor around the tooth portion 3 with aligned winding.
- the coil group 4 is divided into a plurality (four in FIG. 1) of coil segments 5 adjacent to each other in the circumferential direction of the iron core 1.
- the iron core 1 is divided into a plurality (four in FIG. 1) of iron core segments 10 corresponding to the coil segments 5.
- Each coil segment 5 includes first to third stepped coils 6 to 8 adjacent to each other in the circumferential direction of the iron core 1, and a bobbin-shaped coil 9 adjacent to the third stepped coil.
- Each stepped coil 6-8 includes a large-diameter portion 6a, 7a, 8a adjacent to the core back portion 2, and a small-diameter portion 6b adjacent to the large-diameter portion 6a, 7a, 8a inside the core 1 in the radial direction. 7b, 8b. Further, step portions 6c, 7c, and 8c are formed between the large diameter portions 6a, 7a, and 8a and the small diameter portions 6b, 7b, and 8b due to the difference in diameter.
- the number of winding layers of the coil conductors of the small diameter parts 6b, 7b, 8b is less than the number of winding layers of the coil conductors of the large diameter parts 6a, 7a, 8a.
- the diameter is smaller than 6a, 7a, 8a.
- the positions of the step portions 6c, 7c, 8c in each coil segment 5 are shifted inward in the radial direction of the iron core 1 in order from the first stepped coil 6 located at one end portion in the circumferential direction of the iron core 1! / Further, the cross-sectional shapes of the stepped coils 6 to 8 are symmetrical with respect to the center of the tooth portion 3.
- the diameter of both ends in the radial direction of the iron core 1 is larger than the diameter of the intermediate portion. It's getting bigger.
- the cross-sectional shape of the bobbin-shaped coil 9 is also symmetrical with respect to the center of the tooth portion 3.
- FIG. 3 is an explanatory view showing a winding method of the coils 6 to 9 of FIG. Figure 3 (a) shows the state where the first layer is wound.
- the coil conductor 11 in the first layer is wound by the winding machine while being aligned from the winding start portion 11a located on the core back portion 2 side toward the tip portion of the teeth portion 3.
- the coil conductor 11 in the second layer is wound on the first layer while being aligned in the direction opposite to the first layer. Thereafter, similarly, the coil conductor 11 is wound up to the required number of layers.
- Such a winding method is generally called aligned winding.
- the number of layers of the coil conductor 11 varies depending on the position in the length direction of the tooth portion 3.
- the position force of the step portions 6c, 7c, 8c in each coil segment 5 is the iron core in order from the first stepped coil 6 located at one end in the circumferential direction of the iron core 1. Since it is shifted inward in the radial direction of 1, the space factor of the coils 6-9 can be further increased while preventing interference between the coils 6-9. Thereby, damage to the coil conductor 11 can be prevented, and motor characteristics can be stabilized when the rotating electrical machine is a motor.
- the coil group 4 as described above can be easily manufactured by repeating the winding pattern for manufacturing one coil segment 5 by the number of coil segments 5.
- the space factor of the coils 6 to 9 can be further improved.
- the iron core 1 is divided into the iron core segments 10 corresponding to the coil segments 5, the coil segments 5 are wound around the iron core segments 10, and then the adjacent iron core segments 10 are joined together. Segment 5 can be connected, making manufacturing easier.
- the number of force divisions obtained by dividing the iron core 1 into four iron core segments 10 is not particularly limited, and may not be divided.
- the number of stepped coils included in one coil segment is not limited to three, but may be two or four or more.
- the bobbin-shaped coil is not necessarily used but only a stepped coil is used. You may comprise a segment. In this case, since all the coils have similar shapes, the winding program can be unified, making it easier to establish the manufacturing technology and ensuring quality stability.
