Description

Technical Field

[0001] The utility model relates to the technical field of stepping motors, in particular to a two-phase stepping motor. Background Art

[0002] Two-phase stepper motors usually refer to two-phase hybrid stepper motors, which are a type of hybrid motor. Two-phase hybrid stepper motors consist of two parts: a stator and a rotor. Common stators have eight or four poles, with a certain number of small teeth evenly distributed on the pole surface. The coil on the pole can be energized in two directions. Its rotor is also composed of two tooth plates with a certain number of small teeth evenly distributed on the circumference. The two tooth plates are staggered by half a tooth pitch, and an axially magnetized annular permanent magnet is sandwiched between the two tooth plates. All teeth on the same rotor plate have the same polarity, while the polarities of the two rotor plates in different sections are opposite.

[0003] The two-phase stepper motor is a high-precision motor that has been widely used in the field of automated production. The speed of the two-phase stepper motor is adjustable and has strong adaptability. The response speed of the two-phase stepper motor is very fast. In automated control, the operation can be executed immediately after the signal is input, and the reaction speed is very short. It can be widely used in some high-demand scenarios.

[0004] But at the same time, the two-phase stepper motor in the prior art will generate a certain amount of heat when working. If the heat cannot be dissipated in time, it may affect the performance and life of the motor, especially in the scenario of partial high-load operation. The heat dissipation of the two-phase stepper motor will increase sharply, causing damage to the motor and even damage to the equipment or endangering personal safety. Utility Model Content

[0039] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0040] like Figure 1 to Figure 4As shown, this embodiment proposes a two-phase stepper motor, including a motor body 1, and also includes a mounting base 2, a cooling mechanism, a cooling tube 3, an air cooling mechanism, a fan 4 and a support assembly. The mounting base 2 is fixedly connected to the motor body 1, the cooling mechanism is installed on the motor body 1, the cooling tube 3 is slidably connected to the cooling mechanism, and the air cooling mechanism is installed at the tail end of the motor body 1, wherein the air cooling mechanism includes the fan 4, and the support assembly is installed on the motor body 1. When the two-phase stepper motor is in normal use, the air cooling mechanism is started, and the heat on the surface of the motor body 1 is blown away by the fan 4 to prevent the heat generated by the motor from not being dissipated in time and affecting the performance and life of the motor body 1. When the external temperature is high or the motor body 1 works for a long time and is under heavy burden, the heat of the motor body 1 can be taken away by water cooling by starting the cooling mechanism to ensure that the temperature of the motor body 1 does not exceed the standard.

[0041] Among them, the cooling mechanism includes a mounting frame 5, a mounting plate 6, and a matching buckle 7. The mounting frame 5 is fixedly connected to the mounting seat 2, the mounting plate 6 is fixedly connected to the mounting frame 5, the cooling pipe 3 is slidably connected to the mounting plate 6, the fan 4 is fixedly connected to the mounting plate 6, and a plurality of matching buckles 7 are provided. The plurality of matching buckles 7 are fixedly connected to the mounting seat 2, and the cooling pipe 3 is inserted into the groove of the matching buckle 7. When the cooling mechanism is started, the cooling pipe 3 is pushed into the matching buckle 7 and locked, and then cold water is introduced to quickly absorb the heat emitted by the motor body 1.

[0042] Secondly, the air cooling mechanism includes a folding plate 8, a rotating shaft 9 and a guide groove 10. There are four folding plates 8, one end of the four folding plates 8 is fixedly connected to the mounting seat 2, and the other end of the four folding plates 8 is fixedly connected to the cooling tube 3. There are multiple rotating shafts 9, and multiple rotating shafts 9 are rotatably connected to the folding plate 8. There are four guide grooves 10, and the four guide grooves 10 are opened at the four corners of the motor body 1. When the air cooling mechanism is started, the cooling tube 3 is removed from the matching buckle 7, and then the cooling tube 3 is pulled, thereby driving the folding plate 8 to spread out to form a wind-blocking cavity. When the fan 4 is started, wind will flow into the wind-blocking cavity to help the fan 4 body dissipate heat, thereby preventing the motor body 1 from poorly dissipating heat and affecting the life of the motor body 1. Among them, the guide groove 10 plays the role of guiding the wind flow, so that the wind flow directly flows through the motor body 1, and the heat dissipation effect is better.

[0043] Again, the support assembly includes a sliding plate 11, a support plate 12, a limiting hole 13 and a bolt 14. The sliding plate 11 is fixedly connected to the bottom end of the motor body 1, and the support plate 12 is slidably connected to the sliding plate 11. There are multiple limiting holes 13, and multiple limiting holes 13 are opened on the sliding plate 11. The bolt 14 is rotatably connected to the support plate 12. The bolt 14 cooperates with the limiting hole 13. The support assembly is used to support the use of the motor body 1 and provide stability. According to the use position, the bolt 14 is adjusted to which limiting hole 13 is screwed, thereby adjusting the height of the motor body 1 for easy use and installation.

[0044] The output end of the fan 4 and the fan body are on the same axis, and a heat dissipation cavity is formed between the output end of the fan 4 and the guide groove 10, so that the wind blown by the fan 4 can fit the motor body 1 better and improve the heat dissipation effect.

[0045] Finally, the cooling tube 3 is wound around the four sides of the motor body 1 , and a plurality of through holes are provided on the mounting plate 6 for the cooling tube 3 to slide.

[0046] In this embodiment, during the operation of the two-phase stepper motor, the motor body 1 is cooled by the air cooling mechanism. If the motor has been working for a long time and the surface is hot, the cooling tube 3 can be pushed and the cooling tube 3 can be clamped on the matching buckle 7. The input and output ends of the cooling tube 3 are connected, and cold water is passed into the cooling tube 3 to efficiently absorb the heat dissipated by the motor body 1, which has a better heat dissipation effect than the air cooling mechanism. After the motor body 1 stops working, the air cooling mechanism can be switched back to dissipate heat to avoid wasting resources.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
