Description

Technical Field

[0001] The utility model relates to the technical field related to stepper motors, in particular to a hybrid stepper motor simulation device for teaching. Background Art

[0002] The hybrid stepper motor is a stepper motor designed by combining the advantages of permanent magnet and reactive stepper motors. Its working principle mainly relies on the change of electromagnetic field to achieve the purpose of rotation. The structure of the hybrid stepper motor includes two parts: stator and rotor. The stator part is usually composed of coils and magnets, while the rotor part is composed of magnets. The working mechanism of the hybrid stepper motor can be divided into two modes: single-phase drive and two-phase drive. In the single-phase drive mode, only one stator coil is energized, and the magnetic field generated by the coil interacts with the magnet on the rotor, causing the rotor to rotate. In the two-phase drive mode, the two stator coils are energized at the same time, and the two magnetic fields generated are superimposed and act on the rotor, which can provide a more stable magnetic field, thereby improving the rotation stability and smoothness of the rotor.

[0003] Some university courses involve hybrid stepper motors. Teachers need to explain the working principle of hybrid stepper motors to students. However, students do not receive knowledge well through theoretical explanations alone. In order to let students understand hybrid stepper motors more closely, some lecturers will disassemble hybrid stepper motors to explain. However, due to the complex internal structure of hybrid stepper motors, students cannot learn and understand the working principle of reactive stepper motors more intuitively and clearly.

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is a hybrid stepping motor simulation device for teaching, comprising a base 1 and a support platform 2 fixedly arranged on the top of the base 1, a stator simulation structure 3 is fixedly arranged on the top of the support platform 2, and a rotor simulation structure 4 is arranged inside the stator simulation structure 3;

[0022] The rotor simulation structure 4 includes a rotating shaft 41 and a strong magnet 42 fixedly arranged at the bottom of the rotating shaft 41. Silicon steel sheets 43 are arranged at the top and bottom of the strong magnet 42 on the rotating shaft 41. A plurality of salient poles 44 are arranged equidistantly on the outer side of the silicon steel sheet 43 along the circumferential direction, and the salient poles 44 on the two silicon steel sheets 43 are arranged alternately.

[0023] Among them, the stator simulation structure 3 includes two mounting seats 1 31 and 32 which are annular in the vertical direction. The mounting seat 1 31 and the mounting seat 2 32 are fixedly connected by the cooperation of a screw and a nut, and the screw is fixedly connected to the support platform 2. There are four screws and they are equidistantly distributed along the circumferential direction. The screws are connected with the mounting seat 1 31 and the mounting seat 2 32 through an interlaced connection, and then a limiting fixing nut is set on the outside of the screw to achieve fixed connection between the mounting seat 1 31 and the mounting seat 2 32.

[0024] Among them, four groups of coils 33 are equidistantly arranged at the top of the mounting seat 31 in the circumferential direction, and two yokes 34 are arranged on the inner side of each group of coils 33. A cavity 35 is formed between the two yokes 34. When the coils 33 are energized, the two yokes 34 will generate a magnetic field, while no magnetic field will be generated in the cavity 35.

[0025] Among them, four controllers 36 are equidistantly arranged at the top of the second mounting seat 32 along the circumferential direction. The four controllers 36 are respectively arranged corresponding to the four coils 33, and the power supply of the coils 33 is controlled by the controllers 36.

[0026] Among them, the outer diameter of the silicon steel sheet 43 is larger than the outer diameter of the strong magnet 42. A crossbeam 45 is rotatably arranged on the top of the rotating shaft 41 through a bearing. A column 46 is fixedly arranged at one end of the crossbeam 45. One end of the column 46 is fixedly connected to the support platform 2. Through the cooperation between the crossbeam 45 and the column 46, the silicon steel sheet 43 can be rotatably arranged on the inner side of the four coils 33.

[0027] Working principle: The strong magnet 42 is annular, and the upper part of the strong magnet 42 is an S pole, and the lower part is an N pole. There are 9 salient poles 44. Then the 9 salient poles 44 on the upper silicon steel sheet 43 are all S poles horizontally facing outward, and the 9 salient poles 44 on the lower silicon steel sheet 43 are all N poles horizontally facing outward. There are four stator coils 33 outside, one group up and one group left and right.

[0028] First, energize the upper and lower groups, with the polarity of upper N and lower S. At this time, the magnetic field generated by the upper and lower coils 33 after being energized just attracts the rotor as shown in Figure 4;

[0029] The second time, the left and right coils 33 are energized in the manner of left N and right S. At this time, the salient poles 44 are attracted by the magnetic force and drive the shaft 41 to rotate a certain angle.

[0030] The third time, the upper and lower coils 33 are energized with opposite polarity to the first time, so that they generate a magnetic pattern of N at the bottom and S at the top. At this time, the salient pole 44 is attracted by the magnetic force and drives the shaft 41 to rotate a certain angle again.

[0031] The fourth time, the left and right coils 33 are energized with opposite polarities to the second time, so that they generate a magnetic pattern of right N and left S. At this time, the salient pole 44 is attracted by the magnetic force and drives the shaft 41 to rotate a certain angle again.

[0032] By repeating this process over and over again, the working principle of the hybrid stepper motor can be simulated, and the entire plate structure of the simulation device is made of acrylic transparent plate, which allows students to see the working principle of the hybrid stepper motor more intuitively.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
