Linear Motor Of The Computer-aided Design And Simulation

The computer Aided Design of linear motor, is one of the practical application of CAD(Computer Aided Design) technique in the field of electrical machine's design. The CAD technique can fall together the computer's speediness, precision, intuitionist and the designers logical thinking, integrated analytical ability, design's experience. So it accelerates the design's process of production, shortens the design's cycle, improve the automatization of production design. Now, along with the popularization of microcomputer, the rapid development of computer and peripheral equipment, the CAD of electrical machine has occurred distinct changes in content and method. Not only its application is science compute, but also it offers to users by the multifuncti onal integration software system's form. The paper mostly aims at the CAD of linear motor. It builds the development platform of linear machine software by fashionable Visual Basic. It combines the second development of AutoCAD2000 about Visual Basic. Not only it builds the database management system in the Microsoft Access platform, but also it develops the alternating linear machine CAD software system having good user interface. The software system has the characteristic of man-machine conversation. Owing to the Cl is very friend]y, users can know well all kinds of manipulation of the software rapidly not having to compute knowledge. The paper combines the function of computer drawing in the whole CAD system, so the whole electrical machine CAD software integrates the functions of the electrical machine design, the electrical database management system and automatic plotting. The software is so intellectualized that it automatically controls the whole design flow and data transfer. It lightens the designer's burden, and makes them design the electrical machine expediently~ Besides, the paper uses the simulation of the long stator synchronization linear motor in the MAGLEV as an example and introduces the simulation of the linear motor. At present, the software applies in the practical item. The first application is the design of cylindrical linear induction motor in the elevator driven by linear motor. The second application is the simulation of long stator synchronization linear motor in the MAGLEV. Facts have proved that the software completed the tasks successfully. It is obvious that the linear electrical machine CAD software has definite practical value.
