Nanii V. The development of the theory and creating the effective design versions of electric motors with the rolling rotor

3. Research object: electromagnetic, thermal, mechanical processes, modes of operation and field of application motors with rolling rotor. Goal of research: development of the theory and creation of effective design-structural performances of the motor with rolling rotor for direct-drive, determination of applications. Research methods: the theory of electro-magnetic field, theory of thermal processes, strength theory, theory of electric machines. Applied numerical solution of field problems using the finite element method in two - and three-dimensional setting with the help of modern software systems. Experimental studies confirmed by tests at the test station OJSC SKB "Ukrelectromash" ( Kharkiv) and re-source tests. Theoretical and practical results are the establishment of the influence of magnetic flux scattering on еlec-tromechanical energy conversion in the motor, the range of existence of the loading angle, the values of the mechanical losses in the zone of contact of the rotor with the stator, the nature of the modes and the creation of motors, adapted to the requirements of the operation of the actuator valves. Scientific novelty consists in obtaining the full equations of mo-tion of the motor with the rolling rotor, its mechanical characteristics and the effect of friction on the processes in the machine. Degree of implementation: drive horizontal continuous casting machine (JSC "Energoprom", Kharkiv, Ukraine); scientific research Magdeburg University. Otto von Guericke (Germany); electric regulating valve unit pump-ing NP 15.04 (JSC Mechanical plant "Kalyazin", RF, Kalyazin); educational process of NTU "KhPI". Scope: direct drive with low speed and drive rare use of valves and other automatic systems fuel and energy, machine-building, chemical complexes and communal services, the educational process.
