Technical Field

[0001] The utility model relates to the technical field of motor stators with anti-drift structures, in particular to a motor stator with an anti-drift structure. Background Art

[0002] The stator is the stationary part of the motor. It consists of three parts: the stator core, stator windings, and the frame. The stator's primary function is to generate a rotating magnetic field, while the rotor's primary function is to be cut by magnetic lines of force in the rotating magnetic field, generating current.

[0003] The motor mainly consists of an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor and other accessories. Under the action of the rotating magnetic field of the stator winding, current flows through the armature squirrel cage aluminum frame and is caused to rotate by the magnetic field.

[0004] However, during long-term use, the existing motor stator may be affected by the rotor and cause the stator core to shift, resulting in damage to the stator core and affecting subsequent use.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the prior art has the problem that the stator core cannot be supported to prevent deviation during use.

[0007] The utility model discloses a motor stator with an anti-drift structure, comprising a motor housing, an inner wall of the motor housing being slidably connected to a stator body, an inner wall of the stator body being fixedly connected to a stator core, a plurality of first limit plates being slidably connected to the inner wall of the stator core, one end of the first limit plate being fixedly connected to a fixing frame, an outer surface of the motor housing being threadedly connected to a shell cover, an inner wall of the shell cover being rotatably connected to an extrusion plate, a side of the extrusion plate close to the motor housing being fixedly connected to a plurality of fixing blocks, and an inner wall of each of the fixing blocks being plugged into a corresponding first limit plate.

[0008] Furthermore, a plurality of second limiting plates are fixedly connected to the inner wall of the motor housing, a plurality of sliding grooves are provided on the outer surface of the stator body, and the outer surface of each second limiting plate is plugged into the corresponding sliding groove.

[0009] Furthermore, a plurality of screws are inserted into the interior of the housing cover, and the outer surface of each screw is threadedly connected to the motor housing.

[0010] Furthermore, a plurality of plug-in plates are fixedly connected to one side of the extrusion plate close to the motor housing, and a plurality of slots are provided on one side of the stator body close to the plug-in plates, and an inner wall of each slot is plugged into a corresponding plug-in plate.

[0011] Furthermore, a plurality of stepped grooves are provided on one side of the stator body close to the inserting plate, and a connecting rod is slidably connected to the inner wall of each stepped groove.

[0012] Furthermore, the outer surface of each connecting rod is fixedly connected to a limiting ring, the outer surface of each limiting ring is slidably connected to the corresponding step groove, and the end of each connecting rod away from the stator body is fixedly connected to a pull block, and the outer surface of each pull block is clamped with the stator body.

[0013] Furthermore, a spring is sleeved on the outer surface of each connecting rod, and one end of each spring close to the corresponding limiting ring is fixedly connected to the corresponding limiting ring, and the other end is fixedly connected to the corresponding stepped groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model is provided with components such as a stator body, a motor housing, a stator core, a first limiting plate, a fixing block, a shell cover, a fixing frame, and an extrusion plate. The stator core is installed in the stator body, and the first limiting plate is then inserted along the stator core until the fixing frame contacts the motor housing. At this time, the shell cover is installed with the motor housing. During this process, the fixing block will be plugged into the corresponding first limiting plate, so that the first limiting plate can be supported and fixed by the fixing block, thereby achieving the effect that the device can support the stator core through the first limiting plate to prevent it from deflecting during use.

[0016] 2. The utility model is provided with components such as a spring, a connecting rod, a pull block, a limit ring, a stepped groove, a shell cover, and an extrusion plate. During the installation of the shell cover, the extrusion plate will squeeze the pull block. At this time, the pull block will push the corresponding connecting rod to slide along the corresponding stepped groove. At this time, the limit ring will follow the corresponding connecting rod to slide along the corresponding stepped groove. The spring begins to compress. Then, when the shell cover is removed, the spring will push the corresponding pull block to pop out under the action of its rebound force, thereby achieving the effect that the device can quickly remove the stator body by pulling the pull block.
