Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an electric motor used in an axial blower, and in particular to a support structure for its lead wire.

[Conventional technology]

Figures 5 and 6 are, for example, 59-64500
FIG. 5 is a perspective view, and FIG. 6 is an enlarged perspective view of the main parts.

In the figure, 1 is a frame body, and end plates 2 and 3 facing each other
and a cylindrical body connecting these (not shown)
It is made up of 4 is a blade housed in the body, 5 is an electric motor that also drives the blade 4, and 6 is provided on the front surface of the end plate 2 and extends to the peripheral edge of the end plate 2 to guide the lead wire 7 of the electric motor 5. A guide groove 8 is a support groove that communicates with the guide groove 6 and passes through the peripheral edge of the end plate 2 in the thickness direction. A support groove 9 communicates with the support groove 8 and opens at the peripheral edge of the end plate 2, through which 71 lead wires pass. It is an insertion slot with a width that allows

A conventional electric motor for an axial blower is constructed as described above, and the lead wires 7 of the electric motor 5 are drawn out of the end plate 2, pass through the guide groove 6, and are inserted one by one into the support groove 8 through the insertion opening 9. After that, it is pulled out from between the end plates 2 and 3.

[Problem that the invention attempts to solve]

In the electric motor for an axial blower as described above, the lead wire of the motor 5 is drawn out from between the end plates 2 and 3, so the end plate 3 is fixed to the structure and the lead wire 7 is pulled out from between the end plates 2 and 3.
There is a problem in that the end plate 3 becomes jammed when the blower is drawn into the structure, making it difficult to install the blower.

This idea was made to solve the above problem, and it is designed for axial flow blowers that allows the blower to be easily installed without the lead wires being obstructed by the end plate when installing the blower on the structure. The purpose is to provide electric motors.

[Means for solving problems]

In the electric motor for an axial blower according to this invention, grooves for supporting the lead wires of the electric motor are provided on the peripheral edges of each of the opposing end plates.

[Effect]

In this invention, since grooves are provided on the peripheral edges of each of the opposing end plates, the lead wire is supported by the grooves of both end plates and drawn out of the end plates.

〔Example〕

Figures 1 to 4 show an embodiment of this invention, with Figure 1 being a perspective view, Figures 2 and 3 being enlarged perspective views of main parts, and Figure 4 being a front view of the mounting structure. and
1 to 9 are similar to the conventional device described above.

In the figure, 8A is a support groove similar to the support groove 8 provided on the peripheral edge of the end plate 3, and 9A is an insertion port similar to the insertion port 9. However, the front surface of the end plate 3 (on the opposite side in FIG. 3) is not provided with anything corresponding to the guide groove 6. Reference numeral 10 denotes a structure in which a blower is installed, and is provided with a ventilation hole 11 and an insertion port 12 for the lead wire 7.

In the axial blower electric motor configured as described above, the lead wire 7 is drawn out of the end plate 3 from the support groove 8 of the end plate 2 through the support groove 8A of the end plate 3. When the blower is attached to the structure 10, the lead wire 7 is drawn into the other party through the insertion port 12.

In this way, the lead wire 7 is drawn out of the end plate 3 through the support grooves 8, 8A of the end plates 2, 3, and is therefore drawn into the structure 10 without being hindered by the end plate 3, and the blower Installation on the structure 10 is easy.

[Effect of idea]

As explained above, in this invention, grooves are provided on the peripheral edges of each of the opposing end plates to support the lead wires of the motor, so when the blower is installed in the structure, the lead wires do not cross the end plates. This has the effect of allowing the blower to be easily installed without having to be installed.
