Technical Field

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

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and thereby drives the rotor to output torque. The stator and rotor are both important components of the motor. The two components cooperate with each other through the action of the energized coil to convert electromagnetic energy into mechanical energy.

[0003] In the stator and rotor, the stator generates a magnetic field through the winding group, which affects the permanent magnet on the rotor and drives the rotor to rotate. However, the winding slots on the stator contain too much enameled wire, which makes it difficult to produce the stator and rotor. The existing stator and rotor use a detachable stopper to facilitate the insertion of the stator and rotor. However, the detachable stopper has the risk of falling off, which can easily cause the winding group composed of enameled wire to loosen and deform, affecting the magnetic field shape, and then affecting the performance of the stator and rotor.

[0004] Therefore, a stator and rotor having a detachable limiting structure is needed to facilitate winding of the enameled wire on the stator, and the detachable limiting structure is firmly connected to the stator and is not easy to fall off. Utility Model Content

[0012] In the stator and rotor that are easy to wind, a first limiting plate and a second limiting plate are provided on the slider, and the first limiting plate is longer than the second limiting plate.

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 6As shown, the utility model can be implemented through the following embodiments: a stator and rotor that are easy to wind, including a stator assembly 1 and a rotor assembly 2, the rotor assembly 2 includes a rotating shaft 21 and a rotor core 22, the stator assembly 1 includes a stator core 11 and a limit bar 12, a plurality of winding grooves 111 are opened on the stator core 11, winding posts 112 are formed between adjacent winding grooves 111, the limiting strip 12 is installed on the winding post 112, a slide groove 121 is opened in the limiting strip 12, and a slider 1121 matching the shape of the slide groove 121 is provided on the winding groove 111.

[0023] The original winding pole 112 on the stator core 11 is divided into a slider 1121 and a limit bar 12. After the enameled wire is wound on the slider 1121, the limit bar 12 is slidably connected with the slider 1121 on the winding pole 112 through the slide groove 121 of the limit bar 12 to complete the assembly of the stator assembly 1, thereby improving the efficiency of winding the enameled wire on the winding pole 112 and improving the efficiency of producing the stator core 11.

[0024] like Figure 2 and Figure 3 As shown, the length of the slide groove 121 does not exceed the limit bar 12, one end of the limit bar 12 is provided with a mounting portion 122, and the other end of the limit bar 12 is provided with a mounting portion 23. The limit bar 12 is composed of the limit bar 12 body and the mounting portion, which is convenient for the staff to disassemble and install the limit bar 12 on the stator core 11. The length of the slide groove 121 is less than the limit bar 12, leaving space for the installation portion 122.

[0025] like Figures 4 to 6 As shown, the mounting portion 1 122 and the mounting portion 2 3 are provided with a curved arch 5. The curved arch 5 is provided without affecting the strength of the mounting portion 1 122 and the mounting portion 2 3, so as to prevent the limit strip 12 from squeezing the enameled wire during installation and prevent the enameled wire from being damaged and short-circuited due to friction.

[0026] like Figure 4 and Figure 5 As shown, an insertion rod 32 is provided along the edge of the mounting portion 2 3, and a hole 123 of matching shape is provided along the edge of the limiting strip 12. The insertion rod 32 and the hole 123 are used for the butt joint between the limiting strip 12 and the mounting portion 2 3, which facilitates the installation of the limiting strip 12 and the mounting portion 2 3, and prevents the limiting strip 12 and the mounting portion from rubbing against each other to generate vibration, which causes noise when the stator and rotor are in operation.

[0027] like Figure 6 As shown, the mounting part 122 and the mounting part 23 are fixed to the stator core 11 by countersunk screws 4. The countersunk screws 4 fix the mounting part 122 and the mounting part 23 to the stator core 11 to prevent the limiting strip 12 and the mounting part 23 where the mounting part 122 is located from sliding off.

[0028] like Figure 5 As shown, a second slide groove 31 is provided in the second mounting portion 3. The second mounting portion 3 is slidably connected with the winding post 112 of the stator core 11 through the second slide groove 31, and the second slide groove 31 and the winding post 112 play a positioning effect, thereby improving assembly efficiency.

[0029] like Figure 3 As shown, the slider 1121 is provided with a limit plate 1121a and a limit plate 2 1121b, and the limit plate 1121a is longer than the limit plate 2 1121b. The limit plate 1121a and the limit plate 2 1121b are used to limit the radial movement of the slider 1121, and the limit plate 1121a and the limit plate 2 1121b play a certain supporting role; the limit plate 1121a is longer than the limit plate 2 1121b, so that when the motor is working, the slider 1121 is unlikely to have radial runout.

[0030] The working principle of the utility model is as follows: the stator core 11 is fixed, and the enameled wire is wound on the winding pole 112 at the same time, and then the limit bar 12 is slidably connected to the stator core 11 through the slide groove 121 and the slider 1121 of the winding pole 112, and then the mounting part 2 3 is slidably connected to the other side of the stator core 11, and the insertion rod 32 on the mounting part 2 3 and the hole 123 opened on the limit bar 12 are connected, and then the mounting part 1 122 of the limit bar 12 and the mounting part 2 3 are fixed to the stator core 11 through the countersunk screw 4.

[0031] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0032] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
