Today a well-known concept of the use of a synchronous generator with permanent magnet excitation in the power generating system with variable frequency is based on the implementation of voltage control due to the high reactance of the generator. This paper describes an analytical method of calculating the parameters of the generator and voltage quality in the power supply system with variable frequency, which takes into account real parameters of the system required, such as value of the short-circuit current. The analysis of the energy characteristics and power quality of the system in a wide speed range of the generator shaft is presented. Some results of the physical experiments are included to confirm the basic principles of operation of such system.

The paper presents an analysis of a brushless dc motor (BLDC) design solution to be used in the hybrid drive for an unmanned aerial vehicle (UAV), where the designed machine can be operated as the combustion engine starter, generator, and motor. Solutions with external rotor are preferred due to necessity of minimization of the machine weight. Relatively low value of the supply voltage requires that parallel connections within each of the motor phases should be adopted. When selecting optimum pole-arcs of permanent magnets, the relevant analysis concerns not only their influence on the generated cogging torque, electromagnetic torque, and induced voltage, but also circulating currents resulting from the assumed configuration of stator windings. Waveforms of currents, voltages, and the electromagnetic torque are determined for a selected motor working point. Finally, conclusions concerning the analyzed motor are presented.

This paper presents a finite control set model predictive control strategy for the speed control of brushed permanent magnet DC machine. Main objective is to introduce and compare basic cost functions regarding speed control. Full order Kalman filter is used for the observation of the non-measured load torque and reduction of speed measurement noise. Influence of the proposed cost functions on the control quality is demonstrated by simulations. The performance of the best cost function is shown through experimental verification with a 250 W machine and laboratory prototype of H-bridge controlled by RT-LAB control platform.

This paper describes a new circuit to harvest energy from a Peltier elements system using a Switched Capacitors-Boost Converter (SC-BC). The Peltier system produces a high-impedance, low output voltage (4-15 V), that has to be elevetaed, about one order of magnitude (40-150 V) to supply certain applications. Full converter description and operation both, at open-loop and closed-loop using Sliding-mode control (SMC) are aboarded in this work. Experimental and simulated results of a 40W prototype will be given in the paper.

This paper discusses the risks of ignition sources which may appear due to the utilisation of electrical drives in areas at risk of explosive atmospheres. The main goal is to present the traditional approach to mitigation of those risks, as well as to identify its disadvantages. The option to introduce technical diagnostics in the field of explosion protection presents the central part of this paper which discusses the use of technical diagnostics based on the voltage pulse response analysis and cage rotor bars conductivity measurement on induction motor as a reliable tool for detection of ignition sources. Detection of faults which cannot be identified using the traditional approach tools was analysed. Based on the research results the new approach is suggested which allows for the overall and reliable assessment of the explosion protection properties of the motor during its longtime service. Recognition of the need to timely identify induction motor faults in electrical drives, as potential sources of ignition of explosive atmosphere, is the essential conclusion and contribution of this research.

The subject of the paper is focused on the analysis of a 30kW switched reluctance machine for propulsion of electrical vehicle propulsion (EV). The paper details the fundamental steps when developing such an electrical machine, and validates the structure using co-simulation procedures, coupling finite element analysis software (Cedrat Flux2D) with software used to implement the controller (Matlab/Simulink). As the advantages of the SRM are already known, the torque ripples are its main disadvantages. These are reduced as much as possible using a dedicated control strategy, the torque sharing functions (TSF). The solution offered by the paper highlights the possibility of using a cheap, reliable and robust electrical machine for propulsion unit.

The paper is aimed at the analysis of operation of a five-phase induction machine with one phase winding open. It shows different properties of a machine in emergency operation with the stator winding in star, pentagon and pentacle configurations. The currents and torques are determined by means of a developed numerical model. In the paper, the properties of a five-phase machine and a three-phase machine are compared. The optimal way of connecting the stator winding with a feeding source is proposed, so that the machine can continue in emergency operation with a minimal reduction of its power output compared to the operation before a fault.

The paper presents a laboratory robot arm with projection-based safe collision avoidance system which is intended for physical human-robot interaction. This system with new GUI provides also additional functions like movements and individual motors parameters display, so that the man is also informed about the state and activities of the robot arm. This system was designed for teaching, so we have used MATLAB, with which our students have experience.
