Description

Technical Field

[0001] The utility model relates to a motor stator which is convenient for winding, and belongs to the technical field of motor stators. Background Art

[0002] The motor stator is an important part of motors such as generators and starters. The stator is an important part of the motor. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate (output) current.

[0003] For example, CN201985633U discloses a motor stator that is convenient for winding. It uses a large and a small arc block to expand the opening of the winding slot, which is convenient for winding. The arc transition structure between the small arc block and the winding rod can make the enameled wire slide into the slot conveniently, making winding more convenient and easy. In addition, when winding, the two semicircular stator bodies can be wound first and then spliced, which can improve the working efficiency of winding. Although the motor stator structure can disassemble the stator before winding, due to the large number of winding rods in the stator and the compact adjacent positions, there is still a certain degree of operating difficulty when winding, which makes the motor stator less efficient during processing. Utility Model Content

[0004] The utility model aims to provide a motor stator which is convenient for winding. By separating the stator frames and stator cores from each other, winding can be performed on the stator cores separately, so that the stator cores do not need to be blocked by adjacent stator cores during winding, thereby reducing the difficulty of stator winding and improving work efficiency. After the winding is completed, the stator frames can be reconnected and assembled with the positioning blocks and the positioning holes to facilitate the assembly and use of the motor stator, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, the protective shell is rectangular, and four connecting screws are provided and are respectively arranged on four corners of the protective shell.

[0008] Furthermore, a screw hole matching the connecting screw is provided inside the protective shell, and the protective shell is connected to the connecting screw through threads.

[0009] Furthermore, the guide rod has a T-shaped cross section, and a groove for accommodating the guide rod is provided inside the protective shell, and the guide rod is slidably connected inside the protective shell.

[0010] Furthermore, the bottom of the guide rod abuts against the bottom of the groove in the protective shell.

[0011] Furthermore, after the guide rod is connected to the inside of the protective shell, the top end of the guide rod is on the same horizontal line as the upper surface of the protective shell.

[0012] Furthermore, the stator frame is in an arc shape, the stator core is in a trapezoidal shape, and the height of the stator core is lower than the height of the stator frame.

[0013] Furthermore, a positioning block is provided on one side of the stator base, and a positioning hole matching the positioning block is provided on the other side of the stator base.

[0014] Furthermore, the stator frame is connected to the positioning hole through the positioning block.

[0015] Furthermore, the limiting plate is in an arc shape, and the height of the limiting plate is the same as the height of the stator frame.

[0016] The beneficial effects of the utility model are:

[0017] 1. By separating the stator frames and stator cores from each other, winding can be performed on the stator core alone, so that the stator core does not need to be blocked by the adjacent stator core during winding, thereby reducing the difficulty of stator winding and improving work efficiency. After the winding is completed, the stator frame can be reconnected and assembled with the positioning block and the positioning hole to facilitate the assembly and use of the motor stator.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1: Please refer to Figure 1-Figure 10 , the utility model provides a technical solution:

[0033] A motor stator for convenient winding comprises a protective shell 1, a plurality of stator bases 2 are connected inside the protective shell 1, a guide rod 3 is provided on one side of the center of the stator base 2, a stator core 4 is fixedly connected on the other side of the stator base 2, one end of the stator core 4 is fixedly connected to a limiting plate 5, a plurality of connecting screws 6 are connected inside the protective shell 1, the upper part of the connecting screws 6 is fixedly connected to a clamping plate 7, one end of the clamping plate 7 is fixedly connected to a sealing plate 8, and a through hole 9 is opened in the center of the sealing plate 8.

[0034] Specifically, the protective shell 1 is rectangular, and four connecting screws 6 are provided and respectively arranged at the four corners of the protective shell 1. The inside of the protective shell 1 is provided with screw holes matching the connecting screws 6. The protective shell 1 is connected to the connecting screws 6 through threads. The connecting screws 6 can drive the sealing plate 8 and the clamping plate 7 to be pressed on the stator base 2, making it convenient to press the stator base 2 inside the protective shell 1.

[0035] Specifically, the guide rod 3 has a T-shaped cross-section, and a groove for accommodating the guide rod 3 is provided inside the protective shell 1. The guide rod 3 is slidably connected inside the protective shell 1, and the bottom of the guide rod 3 is in conflict with the bottom of the groove inside the protective shell 1. After the guide rod 3 is connected to the inside of the protective shell 1, the top of the guide rod 3 is on the same horizontal line as the upper surface of the protective shell 1. The guide rod 3 can guide the stator base 2 to be connected in the protective shell 1, which is convenient for positioning the stator base 2.

[0036] Example 2: Please refer to Figure 2 , Figure 4 , Fig. 9 The difference between this embodiment and embodiment 1 is that: the stator base 2 is in an arc shape, the stator core 4 is trapezoidal, the height of the stator core 4 is lower than the height of the stator base 2, a positioning block 10 is provided on one side of the stator base 2, and a positioning hole 11 matching the positioning block 10 is provided on the other side of the stator base 2. The adjacent stator bases 2 are connected to each other through the positioning blocks 10 and the positioning holes 11. The limiting plate 5 is in an arc shape, and the height of the limiting plate 5 is the same as that of the stator base 2.

[0037] Working principle of the utility model: when in use, first take out each stator frame 2 and stator core 4 from the protective shell 1 and separate them from each other, and then wind the stator core 4 separately, so that the stator core 4 does not need to be blocked by the adjacent stator core 4 when winding, reducing the difficulty of stator winding and improving work efficiency. After the winding is completed, the stator frame 2 can be connected and assembled with the positioning block 10 and the positioning hole 11 again to facilitate the assembly and use of the motor stator. When installing, insert the guide rod 3 into the protective shell 1 to limit the position of the stator frame 2, and then tighten the connecting screw 6 on the protective shell 1 to press the sealing plate 8 on the stator frame 2 to prevent the stator frame 2 from loosening or falling off in the protective shell 1.
