[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0033] like Figure 1-Figure 3 As shown, the present application provides an anti-interference rotary transformer installation structure, the rotary transformer is installed inside the motor to control the operation of the motor. Generally, the motor has a motor shaft, and the rotary transformer has a stator 3, and the stator 3 is installed on the motor shaft;
[0034] At the same time, multiple groups of fixing blocks 31 are fixedly installed on the outer side of the stator 3, and fixing holes 32 are opened inside the multiple groups of fixing blocks 31. Bolts can be installed inside the fixing holes 32, so that the stator 3 can be connected to the motor by passing the bolts through the fixing holes 32, so that the stator 3 can be fixed inside the motor;
[0035] Due to the different motor models, the installation position of the stator 3 and different motors will change, so it is necessary to change the installation position inside the motor. In order to adapt to different motors:
[0036] The stator 3 is provided with a plurality of slots 33. A first frame 4 is installed on the upper portion of the stator 3, and a second frame 5 is installed on the lower portion of the stator 3.
[0037] At the same time, a first clamping frame 42 is fixedly installed near the bottom of the first frame 4 near the slot 33, and the first clamping frame 42 is adapted to the inside of the slot 33, so that the first frame 4 can be clamped to the inside of the slot 33 through the first clamping frame 42, so that the first frame 4 can be assembled and installed on the upper part of the stator 3;
[0038] A second clamping frame 51 is fixedly installed on the upper part of the second frame 5 near the slot 33. The second clamping frame 51 is adapted to the inside of the slot 33, so that the second frame 5 can be clamped in the slot 33 through the second clamping frame 51, so that the second frame 5 can be assembled and installed at the lower part of the stator 3.
[0039] At the same time, a power block 7 is fixedly installed at one end of the second skeleton 5, and a copper pin 8 is installed inside the power block 7. At the same time, the power block 7 is used to connect external wires, and the copper pin 8 is used to achieve continuous transmission of current or signal;
[0040] The slot 33 can be installed at the first card frame 42 and the second card frame 51 at different positions respectively. After the slot 33 is installed, it will not affect the center position of the stator 3. As the stator 3 can be installed between the first card frame 42 and the protrusion 52 at will, the position of the fixing block 31 will be offset along with the center point of the stator 3, so that the fixing block 31 can touch the installation position of different motors, so that the stator 3 can be suitable for different motor models, and the power block 7 is arranged at one end of the second skeleton 5, so that when the stator 3 is adjusted to the required position, it will not affect the power block 7, so that the power block 7 can be used normally;
[0041] like Figure 3-Figure 4 As shown, a clamping block 41 is fixedly installed on the inner wall of the first frame 4, and a protrusion 52 is fixedly installed on the inner wall of the second frame 5. When the stator 3 is assembled and installed between the first frame 4 and the second frame 5, respectively, as the second clamping frame 51 and the first clamping frame 42 enter the relative slot 33 positions, the clamping block 41 and the protrusion 52 together with the inner wall of the stator 3 will form a whole, and a gap will be formed between the two clamping blocks 41, so that the coil can be wound around the clamping block 41 and the protrusion 52 through the gap;
[0042] like Figure 1-Figure 2 As shown, the first protective cover 1 is clamped on the upper part of the first frame 4, and the second protective cover 2 is clamped on the lower part of the second frame 5. The second protective cover 2 is located close to the motor, so that the first frame 4 and the second frame 5 can be sealed and protected by the first protective cover 1 and the second protective cover 2.
[0043] At the same time, a buckle 11 is fixedly installed at one end of the first protective cover 1, and a slot 43 is opened at one end of the first frame 4, so that when the first protective cover 1 is installed on the first frame 4, the buckle 11 can be snapped into the inside of the slot 43, so as to further improve the installation effect between the first protective cover 1 and the first frame 4, and the second protective cover 2 and the second frame 5 are installed with the same structure corresponding to the first protective cover 1 and the first frame 4;
[0044] Usually there is an electromagnetic field outdoors. In order to prevent the external electromagnetic field from interfering with the operation of the motor, the following are done:
[0045] like Figure 5 As shown, a shielding ring 6 is installed inside the second protective cover 2, and the shielding ring 6 is made of copper. Generally, copper has good magnetic conductivity and can absorb the external magnetic field to a certain extent, so that the external magnetic field can reduce the interference to the rotary transformer through the shielding ring 6.
[0046] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
