Masliennikov A. Methods of specific torque amplification for the rolling rotor engine with a discrete switched mode power supply.

Object of study - the electromagnetic processes in electromechanical energy conversion in the motor with a rolling rotor. The purpose of this study is increase the specific torque of the motor with a rolling rotor at discrete pulse supply. The research methods is finite element method, which is used for calculate the two-dimensional and three-dimensional picture of the magnetic field in the motor with a rolling rotor. To calculate the force of magnetic attraction Maxwell's equations have been used. During the study of the rotor movement process basic principles of the oscillations theory with the Lagrange solution is used. Theoretical and practical results - method of calculating the power of unilateral magnetic attraction and the motor with a rolling rotor torque at discrete pulse supply is developed. The factors affecting to the motor torque and the necessity of the number of stator coils for creation maximum torque of motor with a rolling rotor at discrete pulse supply are defined. Based on theoretical researches designed, manufactured and tested a sample of the motor that compliance with the essential specifications for the single-turn electric machinery. Novelty - first developed a mathematical description of the motion of the rotor in the vicinity of the balance point, determine the required number of coils, maximizing the value of unilateral force of magnetic attraction and for the first time obtained and analyzed the three-dimensional picture of the distribution of the magnetic field in the motor with a rolling rotor at discrete pulse power. The degree of implementation - Department of electrical machines NTU "KhPI", Zmiyevskaya TPS (Komsomolsk, Kharkiv), Rivne Nuclear Power Plant (Kuznetsovsk). Scope of use - pipeline armature energy sector and energy facilities, electric machine building.
