Technical Field
[0001] This utility model relates to the field of servo motor accessories technology, and in particular to a stator wheel structure for a servo motor. Background Technology
[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor with indirect speed change. Servo motors can control speed and have very accurate positioning. They can convert voltage signals into torque and speed to drive the controlled object.
[0003] The installation process of components such as rotor and stator inside existing servo motors is relatively inconvenient. Due to the unreasonable distribution of the number of magnetic poles, it will cause problems such as high power consumption and insufficient power output. In order to address this technical problem, this application proposes a stator wheel structure for servo motors. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a stator wheel structure for a servo motor. By inserting two clips on the right side of the fixing cover into the sleeve and using fixing bolts, the fixing cover can be installed on the left end of the motor stator. This provides guidance and limit for the subsequent installation of the motor rotor, making the installation more accurate and convenient. At the same time, multiple heat dissipation holes are provided on the left end of the fixing cover to allow air circulation and prevent the heat dissipation holes from affecting the normal heat dissipation of the structure.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A stator wheel structure for a servo motor includes a motor stator, with sleeves fixedly connected to both the front and rear ends of the motor stator. A fixing cover is clamped to the left end of the motor stator, and multiple heat dissipation holes are opened on the left end of the fixing cover. Clamping blocks are fixedly connected to both the front and rear sides of the right end of the fixing cover, and a motor rotor is provided on the inner wall of the fixing cover.
[0007] Furthermore, the outer walls of the card blocks are all snapped into the inner walls of the sleeves, and the card blocks and sleeves are connected by bolts.
[0008] Furthermore, the inner wall of the motor stator is provided with multiple stator slots, and the outer wall of each stator slot is wound with an excitation coil.
[0009] Furthermore, a sleeve is fixedly connected to the right side of the outer wall of the motor rotor, and multiple commutators are fixedly connected to the inner wall of the sleeve. An armature is fixedly connected to one end of each commutator.
[0010] Furthermore, a high-carbon steel is fixedly connected to the middle of the outer wall of the motor rotor, and multiple slots are opened on the outer wall of the high-carbon steel, with the outer wall of the armature all set on the inner wall of the slots.
[0011] This utility model has the following beneficial effects:
[0012] 1. In this utility model, the two clips on the right side of the fixing cover are inserted into the sleeve and fixed with the fixing bolts to install the fixing cover on the left end of the motor stator. This provides guidance and limit for the subsequent installation of the motor rotor, making the installation more accurate and convenient. At the same time, the left end of the fixing cover has multiple heat dissipation holes to allow gas to flow and prevent the heat dissipation holes from affecting the normal heat dissipation of the structure.
[0013] 2. In this utility model, the excitation coil inside the motor stator and the armature inside the high-carbon steel are both uniformly distributed in a ring, so that the motor rotor is subjected to balanced magnetic force inside the motor stator, which makes it more stable during rotation. At the same time, the high-carbon steel fixed on the outer wall of the motor rotor can strengthen the magnetic field generated by the armature, thereby improving the rotation efficiency of the structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figure 1-3 An embodiment of this utility model is provided: a stator wheel structure for a servo motor, including a motor stator 1, with sleeves 5 fixedly connected to both the front and rear ends of the motor stator 1, a fixing cover 2 clamped to the left end of the motor stator 1, and multiple heat dissipation holes 3 opened on the left end of the fixing cover 2, with locking blocks 9 fixedly connected to both the front and rear sides of the right end of the fixing cover 2, the outer walls of the locking blocks 9 being clamped to the inner walls of the sleeves 5, and the locking blocks 9 and the sleeves 5 being connected by bolts;
[0023] Specifically, first, align the two locking blocks 9 on the right side of the fixing cover 2 with the two retaining sleeves 5 on the outer wall of the motor stator 1. Then, insert the locking blocks 9 into the retaining sleeves 5 and rotate the fixing bolts with the tool to connect the locking blocks 9 to the retaining sleeves 5. Install the fixing cover 2 on the left end of the motor stator 1. Next, insert the motor rotor 4 into the motor stator 1 until its left end touches the inner wall of the fixing cover 2. At this time, the left and right ends of the armature 8 on the motor rotor 4 will be flush with the left and right ends of the motor stator 1, which plays a guiding and limiting role in the installation of the motor rotor 4 and prevents one end of the motor rotor 4 from protruding into the motor stator 1 after installation, which would affect subsequent rotation. The left end of the fixing cover 2 has multiple heat dissipation holes 3 to allow air circulation and prevent the heat dissipation holes 3 from affecting the normal heat dissipation of the structure.
[0024] Multiple stator slots 10 are provided on the inner wall of the motor stator 1, and excitation coils 6 are wound on the outer wall of each stator slot 10. The motor rotor 4 is provided on the inner wall of the fixed cover 2. A sleeve 11 is fixedly connected to the right side of the outer wall of the motor rotor 4. Multiple commutators 12 are fixedly connected to the inner wall of the sleeve 11. An armature 8 is fixedly connected to one end of each commutator 12. A high carbon steel 7 is fixedly connected to the middle of the outer wall of the motor rotor 4. Multiple slots are provided on the outer wall of the high carbon steel 7, and the outer wall of the armature 8 is located on the inner wall of each slot.
[0025] Specifically, the excitation coil 6 inside the motor stator 1 and the armature 8 inside the high-carbon steel 7 are both uniformly distributed in a ring, so that the motor rotor 4 is subjected to balanced magnetic force inside the motor stator 1, which makes it more stable during rotation. By energizing the excitation coil 6 wound on the outer wall of the stator slot wedge 10, a magnetic field is generated inside the motor stator 1. Then, the brushes energize the commutator 12 on the sleeve 11. At this time, the commutator 12 will generate a magnetic field after being energized, and rotate under the action of the magnetic field inside the motor stator 1, thereby driving the motor rotor 4 to rotate.
[0026] Working principle: In actual use, first align the two locking blocks 9 on the right side of the fixing cover 2 with the two retaining sleeves 5 on the outer wall of the motor stator 1. Then, insert the locking blocks 9 into the retaining sleeves 5 and rotate the fixing bolt with the tool to connect the locking blocks 9 to the retaining sleeves 5. Install the fixing cover 2 on the left end of the motor stator 1. Next, insert the motor rotor 4 into the motor stator 1 until its left end touches the inner wall of the fixing cover 2. At this time, the left and right ends of the armature 8 on the motor rotor 4 will be flush with the left and right ends of the motor stator 1. Then, energize the excitation coil 6 wound on the outer wall of the stator slot wedge 10 to make the motor stator... A magnetic field is generated inside the stator 11, and then the commutator 12 on the sleeve 11 is energized by the brushes. When the commutator 12 is energized, it will generate a magnetic field and rotate under the force of the magnetic field inside the stator 1, thereby driving the rotor 4 to rotate. The excitation coil 6 inside the stator 1 and the armature 8 inside the high carbon steel 7 are both uniformly distributed in a ring, so that the rotor 4 is subjected to a balanced magnetic force inside the stator 1, which makes it more stable during rotation. At the same time, the high carbon steel 7 fixed on the outer wall of the rotor 4 can strengthen the magnetic field generated by the armature 8, thereby improving the rotation efficiency of the structure.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
