Summary: Within this project a software packages for numerical calculation of electromagnetic fields were developed. The aim is to utilize the packages in procedures for development and design of electromagnetic devices for generation, distribution and conversion of electrical energy, in order to increase quality of electromagnetic design and to decrease the time of development cycle. The software packages are based on application of finite element method and were applied in next areas: - numerical calculation of magnetic field and torques in switched reluctance motor, - numerical calculations of leakage fields in electrical machines, - numerical field calculations and development of new type of low-voltage circuit breaker, - calculation of integral parameters of synchronous permanent magnet motor, - numerical calculation of electric cable parameters, - electromagnetic field influence on living beings. The results of the calculation were compared with measurements on models which proved the applicability of the packages. The application of package "SPLT" result in patent for new type of current limiter.

Keywords: electromagnetic fields, numerical field calculation, development and computer aided design, electric motors, current limiter circuit breaker, electromagnetic influence

Research goals: Utilization of complex mathematical models and numerical analysis of electromagnetic fields in development and design of electrical machines and apparatus is a prerequisite for implementation of new technologies and shortening of development cycle. The most widely spread method for computation of electromagnetic fields is the finite element method due to its flexibility and possibility of development of user-oriented programming packages aimed for utilization by non-specialists users. The main goal of the project is development of programme packages for electromagnetic field calculation which can be applied in various areas of electrical engineering. The applicability of programming packages was examined on examples: - computation of torques and forces in switched reluctance motor, - calculation of leakage fluxes in electrical machines, - calculation and development of the new type of low-voltage current-limiting circuit breakers, - calculation of integral parameters of synchronous permanent magnet motor - calculation of electric cable parameters, - calculation of electromagnetic field influence. The results of calculations were compared with measurements.
