Summary: The properties of electrical machines supplied by static converters (rectifier power supply and inverter power supply) for DC machines and induction machines are analysed. For that the researches of the parasitic phenomena (additional losses, parasitic torques, noise and vibrations) are carried out. The results of computations of main electrical, mechanical and thermal values, at sinusoidal voltage supply and inverteter power supply of induction machines, are compared with results of measurements. Optimal modes of control of electrical machines for some torque-speed characteristics are analysed. Researches of some special measuring methods and automation of standard measring methods of electrical machines are carried out. The influences of stresses, which occurs at heavy working conditions, on deformations of mechanicl elements of machines are analysed.

Keywords: Electrical machines, static converters supply, parasitic phenomena, additional losses, oscilating torques, noise, vibrations, commutation, temperature rise, control of electrical machines, automatic testing, stresses and deformations.

Research goals: - To clarify the phenomena that occurs in electrical machines supplied from static converters; to determine their influence in designing of electrical machines and on choice of materials for their construction - To make basis for mathematical model development, which enables more accurate determination of behaviour of electrical machines in electromotor drives - To develope measuring methods and to automate the measurements for testing the characteristics of electrical machines The application of research results will enable better using materials in construction of electrical machines, increase the reliability of machines, enable energy saving during exploitation of machines, and reduce adverse effects on human environment (noise and vibrations).
