The three-phase asynchronous motor model is YD100L-6/4/2, the number of poles is 6/4/2, the rated power is 0.75KW1.3KW1.8KW, the rated voltage is 380 (V), the rated speed is 960/1400/2800 (rpm), the motor is installed on a steel plate trolley, equipped with four universal wheels, with a special motor connection cable, and 1 electromagnetic brake motor.
4. M*ntenance of electrical and electronic motors and professional qualification tr*ning and assessment simulation software
This software is in apk format and can be used on PC or mobile terminals. This software can set faults manually or automatically. This software selects the manual setting of fault points through the green box in the circuit diagram (up to 39 fault points can be set), and can also be set by the system automatically for random 1 fault point setting, random 2 fault points setting, random 3 fault points setting, random 4 fault points setting, random 5 fault points setting. This software has toolbox, component library, magnifying glass, circuit diagram and other functions. You can select a multimeter for detection through the toolbox, select appropriate components through the component library, and use a magnifying glass to clearly understand each component and circuit. This software sets the fault of the motor star-delta starting control circuit and, after various investigations, allows students to understand the working principle and circuit structure of the motor star-delta starting control circuit.
5. Virtual spectrum analyzer, logic analyzer, oscilloscope, three-meter simulation software:
This software is in apk format and can be used on PC or mobile. The functions of this software include: resistance measurement, AC voltage measurement (measuring transformer, if the transformer burns out the multimeter, black smoke will be emitted and the multimeter can be reset), transistor polarity judgment, DC voltage measurement (the light is on when the ammeter is turned on), DC current measurement, and judgment of the quality of capacitors. This software can drag the red and black pen heads at will. When the two pen heads are dragged to the object to be measured, a red circle will be displayed. If the positioning is not accurate, no red circle will be displayed. When an incorrect operation is performed (such as the selected range is wrong, the measured data is wrong, etc.), the instrument pointer will not respond, prompting an error to re-measure, etc. This multimeter can select AC voltage, DC voltage, resistance, current, resistance adjustment 0, and can enlarge the displayed data, so that the size of the measured data can be clearly viewed. Students can learn the correct use of the multimeter through this software.
6. Single-chip microcomputer , PLC programmable design and control virtual simulation software (copyright certificate and demonstration video are required):
1) This software is developed based on Unity3D, with built-in experimental steps, experimental instructions, circuit diagrams, component lists, connection lines, power on, circuit diagrams, scene reset, return and other buttons. After the connection and code are correct, the three-dimensional machine tool model can be operated through the start/stop, forward movement, and reverse movement buttons . When the line is connected, the three-dimensional machine tool model can be enlarged/reduced and translated.
2) Relay control: Read the experimental instructions and enter the experiment. By reading the circuit diagram, select relays, thermal relays, switches and other components in the component list and drag and drop them to the electrical cabinet. The limiter is placed on the three-dimensional machine tool model. You can choose to cover the lid. Some component names can be renamed. Then click the connection line button to connect the terminals to the terminals. After the machine tool circuit is successfully connected, choose to turn on the power and operate. If the component or line connection is wrong, an error box will pop up. The scene can be reset at any time.
3) PLCControl: The experiment is the same as relay control, with the addition of PLC control function. After the connection is completed, enter the program writing interface through the PLC coding button, write two programs, forward and reverse, with a total of 12 ladder diagram symbols. After the writing is completed, select Submit for program verification. After successful verification, turn on the power to operate. Components, line connections, and code errors will pop up prompt error boxes, and the scene can be reset at any time.
4) Single-chip microcomputer control: The experiment is the same as relay control, with the addition of single-chip microcomputer control function. After the connection is completed, enter the programming interface through the C coding button, enter the correct C language code, and submit after successful verification, turn on the power to operate. Components, line connections, and code errors will pop up prompt error boxes, and the scene can be reset at any time.
