Показаны принципы автоматизированного формирования геометрической и физической моделей трехфазных асинхронных двигателей на алгоритмическом языке Lua для расчета их магнитных полей и параметров в программной среде пакета FEMM. Представлены теоретические основы, алгоритм и текст программы с подробными комментариями, файл исходных данных, а также краткая инструкция для работы со скриптом Lua и примеры получаемых результатов. Возможности составленного скрипта Lua демонстрируются на примере реального четырехполюсного асинхронного двигателя мощностью 15 кВт.
Attention to the popular FEMM (Finite Element Method Magnetics) program, effective in the numerical calculations of the magnetic fields in electrical machines is attended. The main problem of its using – high time costs on the formation of a graphical model, representing the construction and on the formation of a physical model, representing materials properties and machines winding currents, is solved. Principles of an automated formation of such models on the three-phase induction motor example are developed and presented for this purpose. A program written in an algorithmic language Lua which integrated into the package FEMM realize this task. The program is universal from the standpoint of varying the geometry and dimensions of the designed three-phase induction motor. It uses a minimum of input information in a digital form, representing the design of the whole three-phase induction motor and its fragments. A general structure of the Lua script is given, significant parts of its text, the graphic results of work's phases, as well as explanations of the program and instructions for its use are provided. Performance capabilities of the compiled Lua script on the example of the real 15 kW three-phase induction motor are presented.
