[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stator for a four-pole shaving motor used for blowing oil fan heaters.

[0002]

[Prior Art]

 In recent years, in oil-fired heating equipment, the demand for fan heaters has been increasing in place of conventional stoves. It is said that the bobbin winding terminal type is more advantageous than the general straight lead wire drawing type in terms of productivity and versatility of the stator structure of the four-pole shading motor used for blowing air. .

The structure of a conventional bobbin winding terminal type four-pole clearing motor will be described below with reference to FIG.

As shown in the drawing, coil bobbins 24, 25, 26 and 27, in which a shading coil 22 and a field coil 23 are wound, are arranged at four places of the field pole portion of the core 21 in the stator, and the coil bobbin 24 is provided with the coil bobbins 24. Is provided with a terminal block 28 integrally formed with the coil bobbin body. The terminals 29 and 30 are supported on the terminal block 28. The winding start coil end 31 of the field coil 23 is connected to the terminal 29, and the coil bobbins 24, 25, 26, 27 are wound in this order, and then the winding end coil end 32 is connected to the terminal 30. After the winding, the stator outer core 33 was press-fitted and fixed to the stator inner core 21.

[0005]

[Problems to be solved by the device]

 In such a conventional configuration, since the terminals 29, 30 are both supported by the terminal block 28, the winding end coil end 32 has a long transition, and the insulation between this and the field coil wound on the coil bobbin 24 is increased. There were problems such as difficulty in securing the distance and easy disconnection.

The present invention solves the above problems, and ensures the insulation distance between the end-of-winding coil end and the start-of-winding coil, and prevents the occurrence of wire breakage. It is an object to provide a stator for a motor.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the stator of the four-pole shading motor of the present invention is wound around a stator inner core in which four shading coils are arranged in the field pole and four coil bobbins around the inner stator core. Field coil, and a stator outer core that is press-fitted and fixed to the inner core of the stator to form a magnetic circuit after winding. The coil bobbins at the beginning and end of the four coil bobbins are integrally formed. The winding start field coil terminal is on the terminal supported on the winding start coil bobbin terminal block, and the winding end field coil terminal is on the winding end coil bobbin terminal block. Configure by connecting to supported terminals.

[0008]

[Action]

 According to the present invention, since the terminal to which the winding end coil terminal is connected is located in the vicinity of the winding end coil bobbin with the above-described configuration, it is possible to shorten the winding end coil end, and as a result, to secure the insulation distance. It is possible to suppress the occurrence of disconnection.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

As shown in the drawing, coil bobbins 4, 5, 6 and 7 in which a shading coil 2 and a field coil 3 are wound are arranged at four places of a field pole portion of a core 1 in a stator. The coil bobbin 4 at the beginning of winding and the coil bobbin 7 at the end of winding are provided with terminal blocks 8 and 9 integrally formed with the main body, and the terminal blocks 8 and 9 support terminals 10 and 11, respectively. Then, the winding start coil end 12 of the field coil 3 is connected to a terminal 10 supported by a terminal block 8 integrally formed with the winding start coil bobbin 4, and the coil bobbins 4, 5, 6, 7 are wound in this order. After that, the coil end 13 at the end of winding is connected to the terminal 11 supported by the terminal block 9 integrally formed with the coil bobbin 7 at the end of winding, and after winding, the outer core 14 of the stator is press-fitted and fixed to the inner core 1 of the stator. To be done.

As described above, according to the embodiment of the present invention, since the terminal 11 to which the winding end coil end 13 is connected is located in the vicinity of the winding end coil bobbin 7, the winding end coil end 13 is shortened. It will be possible.

[0012]

[Effect of the device]

 As is apparent from the above-described embodiments, according to the present invention, since the terminal to which the winding end coil terminal is connected is located near the winding end coil bobbin, the winding end coil can be shortened. It is possible to provide a bobbin winding terminal type four-pole shading motor stator in which the insulation distance between the winding end coil end and the winding start coil is ensured and the occurrence of wire breakage is prevented.
