Technical Field

[0001] This utility model relates to the field of education, specifically a portable teaching and demonstration box for electric motors. Background Technology

[0002] In teaching electrical machinery, traditional teaching aids are typically motor models. These models may have transparent shells to allow observation of the internal structure, or be designed as cross-sections to enable students to intuitively understand the structure and working principles of motors. However, these teaching aids have some limitations, such as the inability to demonstrate the dynamic separation process of the stator and rotor, a lack of connection with the knowledge of motor design itself, and a lack of integration with stepper motor knowledge. Furthermore, existing motor models lack digital elements, which limits their application in modern education. Utility Model Content

[0003] In order to overcome the above-mentioned defects and deficiencies in the existing technology, this utility model provides a portable teaching and demonstration box for motors. It can not only display the structure and principle of motors, but also dynamically demonstrate the separation process of stator and rotor. Furthermore, it can be combined with motor design knowledge and stepper motor knowledge, and also has digital functions.

[0033] Preferably, the moving component includes a transparent housing 41, a stator 42, and a winding 43. The winding 43 is placed inside the transparent housing 41. The winding 43 and the transparent housing 41 are fixed to the single-axis motion module. The stator 42 is fixedly connected to the stator support clamp 44 through a bearing that passes through the stator support clamp 44. The bottom of the stator support clamp 44 is fixedly connected to the base. The base is fixed to the upper panel 2.

[0034] Preferably, the single-axis motion module includes a stepper motor 31 consisting of a driver and a motor body, a ball screw 32, a coupling 33, a slider 34, and a linear slide rail 35. The motor body of the stepper motor 31 is connected to the ball screw 32 via the coupling 33, and the motor body of the stepper motor 31 is fixedly connected to the base. The ball screw 32 passes through the slider 34, which is fixedly connected to the bottom of the winding 43. The slider 34 is slidably connected to the linear slide rail 35 fixed on the base, and the slider 34 is fixedly connected to the transparent shell 41 and the winding 43 in the moving parts. The driver is used to drive and control the motor body of the electric stepper motor 31. The linear slide rail 35 is fixedly connected to the base.

[0035] Preferably, the fixing member includes a rotor 61 and a rotating shaft 62, the rotating shaft 62 passing through the rotor 61 in its entirety, and the rotating shaft 62 is fixed to the stator support clamp 44.

[0036] Preferably, the control components within the control and communication unit include a power supply, a controller, a release button, a reset button, a limit switch, and a USB connector.

[0037] The control power supply is used to power the controller and the driver;

[0038] The controller is used to receive commands from the release button and the reset button, control the operation of the stepper motor 31 through the driver, and provide feedback on the position of the moving parts through the limit switch. The controller also communicates with the host computer through a USB connector.

[0039] The separation button is used to execute the separation command between the stator 42 and the winding 43 in the model motor;

[0040] The reset button is used to execute the reset command for the stator 42 and winding 43 in the model motor that are in a separated state;

[0042] Example 1: As Figure 2 and Figure 3 As shown, during the movement of the model motor in this utility model, the model motor is displayed in the form of a separate stator 42 and winding 43. The winding 43 and the transparent shell 41 are fixed on the single-axis motion module. The single-axis motion module pulls the ball screw 32 to move the slider 34 by rotating the stepper motor 31.

The control power supply powers the controller and driver. The release button and reset button are connected to the controller, as are the limit switches. The controller connects to a host computer via a USB connector. When the computer presses the display button, it controls the stepper motor 31 to rotate via USB for display. Reaching the end triggers the limit switch, which in turn triggers a voltage signal, stopping the stepper motor 31. Similarly, when the computer presses the reset button, it controls the stepper motor 31 to rotate via USB for display. Reaching the end triggers the limit switch, which in turn triggers a voltage signal, stopping the stepper motor 31. In use, the power is turned on, the controller is connected to the host computer via USB, the serial port is selected, and then the serial port is opened to perform display, reset, and forward / reverse rotation.

[0044] In this third embodiment: After the control power supply is connected to the instrument box, three buttons (power switch, disconnect button, and reset button) are used to switch the power supply. After the power output from the instrument box is plugged into the stepper motor 31, the stepper motor 31 will rotate. Work process: An external AC220 power supply is used to power the instrument box through a three-prong plug. After pressing the start and forward rotation buttons, the instrument box outputs a positive voltage, activating the stepper motor 31, which then rotates in the forward direction. After pressing the start and reverse rotation buttons, the instrument box outputs a reverse voltage, activating the stepper motor 31, which then rotates in the reverse direction.
