Information × Registration Number 0200U003297, 0197U001921 , R & D reports Title Development of improved multilevel mathematical models providing optimal choice of parameters of electric machines at their designing with the purpose of rise of energy metrics. popup.stage_title Head Novikov Yu. D., Registration Date 18-04-2000 Organization The Kharkov state polytechnical university popup.description2 The common mathematical relations taking into account. nonlinearity of the characteristics f magnet systems, main and commutating poles, volt-ampere characteristics of brush contact, effect of a transversal armature reaction, eddy current in massive units, currents of switched sections, change of parameters of the computer are obtained during transient. The general purpose relation for the registration of the enumerated factors is obtained. The analytical technique of the registration of effect of upper harmonics of a magnetic induction on of effect of upper harmonics of a magnetic induction on characteristics of induction motors designed. The new key diagram of a welding generator is offered. The practical circuit scheme of calculation of the characteristics of the new generator with the combined system of energization designed.
