Shaded-pole motors are usually used in conjunction with gearboxes and are mainly used in air conditioners, washing machines, and electric fans. The stator windings and stator cores of existing shaded-pole motors are usually fixed in place, which is not convenient for disassembly. Therefore, this application proposes a shaded-pole motor with an improved stator winding fixing device. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figures 1 to 3 The present invention discloses a shaded-pole motor with an improved stator winding fixing device, comprising a lower support frame 1, a stator core 2, a stator winding 3, a rotor assembly 4, and an upper support frame 5. The stator core 2 is connected to the top of the lower support frame 1, the stator winding 3 is connected to one end of the stator core 2, the rotor assembly 4 is rotatably connected to the inside of the stator core 2, and the upper support frame 5 is connected to the top of the stator core 2. Four screws 6 and a lower positioning rod 7 are fixedly installed on the lower support frame 1. All four screws 6 penetrate the stator core 2, and each of the four screws 6 is provided with a nut 8. A U-shaped positioning rod 9 matching the stator winding 3 is fixedly installed at one end of the top of the upper support frame 5.

[0020] During assembly, first snap the stator core 2 with the stator winding 3, install the rotor assembly 4 into the stator core 2, then install the stator core 2 onto the top of the lower support frame 1, and finally install the upper support frame 5. Connect and fix the lower support frame 1 and the upper support frame 5 with four screws 6 and nuts 8.

[0021] The stator core 2 is composed of a U-shaped core 10 and a straight core 11. The straight core 11 is connected to one end of the U-shaped core 10. The stator winding 3 is composed of a frame 12 and a coil 13. The frame 12 is sleeved on the outer surface of the straight core 11 and connected to the U-shaped core 10. The coil 13 is wound on the frame 12. Two positioning slots 14 connected to the lower positioning rod 7 are opened on one side of the frame 12. Two positioning slots 15 connected to the U-shaped positioning rod 9 are opened on the other side of the frame 12.

[0022] When assembling the stator core 2 and the stator winding 3, first insert the straight core 11 into the frame 12, and then snap the stator winding 3 into the U-shaped core 10. When the stator core 2 and the stator winding 3 are assembled with the lower support frame 1 and the upper support frame 5, the lower positioning rod 7 coincides with the positioning groove 14 to achieve the limit, and the U-shaped positioning rod 9 coincides with the positioning groove 15 to achieve the limit, which improves the connection stability and also allows the stator winding 3 to be disassembled later.

[0023] The stator core 2 has four screw mounting holes 16 that match the screw 6, and the upper support frame 5 has four screw mounting holes 17 that match the screw 6, so that it can be connected to the screw 6.

[0024] The lower support frame 1 has four fixed lower positioning plates 18 at the top corners that fit against the side of the stator core 2, and the upper support frame 5 has four fixed upper positioning plates 19 at the bottom corners that fit against the side of the stator core 2. The lower positioning plates 18 and the upper positioning plates 19 can achieve auxiliary positioning and further improve the stability of the connection.

[0025] The stator core 2 has a rotor mounting slot 20 that matches the rotor assembly 4, which allows the rotor assembly 4 to be installed. The top of the stator core 2 is provided with a rotor support frame 21, which can limit the position of the rotor assembly 4. The rotor support frame 21 is fixedly connected to the stator core 2 by two bolts 22, which can improve the installation stability of the rotor support frame 21. The rotor shaft on the rotor assembly 4 is rotatably connected to the rotor support frame 21 by bearings, which can improve the mobility of the rotor shaft.

[0026] During operation, the lower and upper support frames provide overall support and reinforcement, and can connect with the reducer housing, enabling the shaded-pole motor to work in conjunction with the reducer. The lower positioning rod, U-shaped positioning rod, positioning slot one, and positioning slot two connect and limit the stator winding to the stator core, facilitating subsequent disassembly of the stator winding. The screw mounting holes one and two allow connection with the screw. The lower and upper positioning plates provide auxiliary positioning for the stator core, improving connection stability. The rotor support frame limits the rotor's position, enhancing rotor stability.
