[0019] Specifically, the stator assembly 1 is provided with a plurality of coil supports 11, and a coil structure 3 is provided on any of the coil supports 11. The plurality of coil structures 3 are connected in series based on a connecting line 6, so that the shaded-pole motor can integrate a plurality of coil structures 3 to improve the adjustment range of the output power of the shaded-pole motor, so that the shaded-pole motor can meet the requirements of different power outputs and achieve multi-speed adjustment.

[0020] Furthermore, a plurality of coil supports 11 are arranged around the rotor assembly 2, so that the rotor assembly 2 is located between the plurality of coil supports 11, thereby improving the rationality of space utilization of the structural coordination arrangement of the coil supports 11 and the rotor assembly 2, making the structural arrangement of the shaded-pole motor compact and simplifying the overall size of the shaded-pole motor.

[0021] The coil support 11 is provided with an electrical connection port 113, from which several gear adjustment lines and a control main line extend outwardly. An output connection line of the shaded pole motor is constructed based on the several gear adjustment lines and the control main line to electrically connect the shaded pole motor.

[0022] Specifically, in this embodiment, the stator assembly 1 is provided with two installation positions of the coil brackets 11, so that two symmetrically distributed coil brackets 11 can be provided in the stator assembly 1, and the rotor assembly 2 is arranged in the middle position of the stator assembly 1, so that the overall structural mass of the shaded pole motor is evenly distributed, so that the shaded pole motor can be installed in an external working equipment.

[0023] Based on the two coil structures 3 set by the two coil supports 11, three gears and one control main line are set in the shaded pole motor. The external drive circuit of the shaded pole motor is connected through the three gear adjustment lines and one control main line, so as to realize rapid adjustment of the output speed of the shaded pole motor.

[0024] Furthermore, a gear adjustment line and a control main line are arranged on the coil bracket 11 of one of the coil structures 3 to realize the electrical connection requirements between the shaded-pole motor and the external working circuit. A connecting line 6 is arranged between the two coil structures 3 so that the two coil structures 3 can be connected in series, and the rotor assembly 2 is arranged between the two coil structures 3 so that the connecting line 6 between the two coil structures 3 can be arranged under the rotor assembly 2, thereby improving the rationality of the spatial structure utilization of the shaded-pole motor.

In the present embodiment, the two coil supports 11 are provided with a connecting wire 6 for realizing the series connection between the two coil supports 11. The connecting wire 6 is sleeved with the insulating sleeve 62.

[0033] Furthermore, one end of the wire rack terminal 7 is inserted into the slot 116, and the other end of the wire rack terminal 7 extends outside the slot 116, so that the enameled wire led out of the coil structure 3 of the coil support 11 can be wound around the wire rack terminal 7, thereby forming an electrical connection position of the shaded pole motor, so as to facilitate the electrical connection of the coil structure 3 inside the shaded pole motor and the electrical connection between the shaded pole motor and the external working circuit.

[0039] Furthermore, based on the lower winding area 723 and the upper winding area 722, the contact area between the enameled wire lead-out of the coil structure 3 and the bobbin terminal 7 can be increased, thereby improving the connection stability and reliability between the enameled wire lead-out of the coil structure 3 and the bobbin terminal 7, so that the electrical connection structure of the shaded-pole motor can meet the use requirements of the shaded-pole motor.

[0040] Specifically, the plug-in section 73 of the wire rack terminal 7 is provided with a plurality of barbs 731 arranged in a zigzag shape, so that when the wire rack terminal 7 is plugged into the slot 116 of the coil support 11 based on the plug-in section 73, the plurality of barbs 731 can squeeze the inner wall of the slot 116, thereby increasing the contact friction between the wire rack terminal 7 and the slot 116, so that the wire rack terminal 7 can fit tightly in the slot 116, thereby improving the stability of the fit between the wire rack terminal 7 and the coil support 11.

[0041] Specifically, Figure 6A structural bottom view of a shaded-pole motor in an embodiment of the present invention is shown, wherein a plurality of adjusting sleeves 61 are provided on the connecting wire 6, wherein the adjusting sleeve 61 is configured as an L-shaped structure, and the adjusting sleeve 61 is sleeved on the connecting wire 6, and the folding position and the connection direction of the connecting wire 6 are adjusted based on the adjusting sleeve 61, and the connection direction of the connecting wire 6 is adjusted based on a plurality of adjusting sleeves 61, so that the connecting wire 6 can meet the connection requirements between different coil supports 11, and is helpful to adjust and sort out the arrangement structure of the connecting wire 6, thereby improving the rationality and neatness of the arrangement structure of the connecting wire 6 of the shaded-pole motor.

[0042] Furthermore, based on the connecting wire 6, the coil structures 3 of different coil supports 11 are connected in series, so that the coil structure 3 of the shaded pole motor can lead out enameled wires of different gears, and the enameled wires of different gears are connected to the external working circuit, so that the shaded pole motor can adjust the number of turns of the coil structure 3 entering the working state based on the control signal, thereby realizing the output of different speeds of the shaded pole motor and meeting the use requirements of the shaded pole motor.
