The paper presents the results of the calculations of the magnetic field for the both shielded and non-shielded 3-phase MR 250 busbar manufactured by Elektromontaż 2 in Katowice, Poland. The busbar magnetic field has been determined by the following methods: analytical method for non–shielded busbar without taking into account the skin and proximity effects, analytical–numerical method based on integral equations, twodimensional method of finite elements with the use of the commercial FEMM software, measurement method on a test stand. The measurements were performed with the use of a special non-directional magnetic field meter. A satisfactory compliance of the calculations has been obtained.

The paper deals with analyses of multiphase fractional slot permanent magnet synchronous machines with concentrated windings. The advantages of studied machines have been discussed. Studied in the paper multiphase machines contain the number of phases in multiple of 3, facilitating the application of commonly used 3–phase intelligent power modules to build the multiphase supply system. The coding convention, an algorithm and software for synthesis and analysis of multiphase fractional slot concentrated windings have been developed. To verify presented algorithm the field approach has been employed. The professional FEM package Maxwell has been used to determine functional parameters of the test machine with different types of windings. Selected results of simulations of studied multiphase machines with different phase number and winding layouts have been presented and analyzed.

In this paper, a reference is made to the subject of remote control of certain parts of a residential building via Bluetooth using the mobile device. In the first place, the wireless data transmission via Bluetooth is described. Then, the paper deals with the design of the building and the electronic system based on a microcontroller from the ATmega family that communicates with mobile devices via Bluetooth wireless data transmission. The design includes lightning system, roller blinds, a fan and a garage door. The control is based on the system consisting of a triac and an opto–triac. In addition to this, a control application for Android system is created to enable the remote control by means of a mobile device.
