| description |
Purpose. The purpose of the article is to determine the influence of the initial displacement of the windings on the indicators of an electromechanical induction accelerator of a cylindrical configuration with pulsed excitation from a capacitive energy storage and with short-term excitation from an alternating voltage source. Methodology. To take into account the interrelated electrical, magnetic, mechanical and thermal processes, as well as a number of nonlinear dependencies, we use the lumped parameters of the windings, and the solutions of the equations describing these processes are presented in a recurrent form. The mathematical model of the accelerator takes into account the variable magnetic coupling between the windings during the excitation of the inductor winding. When calculating the parameters and characteristics of the accelerator, a cyclic algorithm is used. Results. At a frequency of an alternating voltage source of 50 Hz, the current amplitude in the armature winding is less than in the inductor winding. With an increase in the source frequency to 250 Hz, the phase shift between the winding currents decreases. The current in the inductor winding decreases, and in the armature winding it increases. The accelerating components of the force increase, and the braking ones decrease. With an increase in the source frequency to 500 Hz, the current density in the armature winding exceeds that in the inductor winding. In this case, the phase shift between the windings is further reduced. Originality. When a cylindrical accelerator is excited, the largest amplitude of the current density in the inductor winding occurs at the maximum initial displacement of the windings, but the amplitude of the current density in the armature winding is the smallest. The largest value of the current density in the armature winding occurs in the absence of an initial displacement. When excited from a capacitive energy storage, the electrodynamic force between the windings has an initial accelerating and subsequent braking components. As a result, the speed of the armature initially increases to a maximum value, but decreases towards the end of the electromagnetic process. When a cylindrical accelerator is excited from an alternating voltage source, a phase shift occurs between the currents in the windings, which leads to the appearance of alternating accelerating and decelerating components of electrodynamic forces. The accelerating components of the force prevail over the braking components, which ensures the movement of the armature. Practical value. At a frequency of an alternating voltage source of 50 Hz, the highest speed at the output of the accelerator vzf=0.5 m/s is realized at an initial displacement of the windings z0=6.2 mm, at a frequency of 250 Hz, the highest speed vzf=2.4 m/s is realized at z0=3.1 mm, and at a frequency of 500 Hz the highest speed vzf=2.29 m/s is realized at z0=2.3 mm. |

В електромеханічному індукційному прискорювачі циліндричної конфігурації найбільша амплітуда струму в обмотці індуктора виникає при максимальному початковому зсуві, але амплітуда струму в обмотці якоря при цьому найменша. Найбільша величина струму в обмотці якоря виникає при відсутності початкового зсуву. При збудженні від ємнісного накопичувача енергії електродинамічна сила між обмотками має початкову прискорювальну і подальшу гальмівну складові. Внаслідок цього швидкість якоря спочатку зростає до максимально величини, але потім зменшується до моменту закінчення електромагнітного процесу. При збудженні прискорювача від джерела змінної напруги (ДЗН) між струмами в обмотках виникає фазовий зсув, що призводить до почергової зміни прискорювальних і гальмівних складових електродинамічної сили. Прискорювальні складові сили переважають над гальмівними складовими, що забезпечує переміщення якоря. При частоті ДЗН 50 Гц амплітуда струму в обмотці якоря менше, ніж в обмотці індуктора. Зі збільшенням частоти ДЗН фазовий зсув між струмами обмоток зменшується, струм в обмотці індуктора зменшується, а в обмотці якоря збільшується. Прискорювальні складові сили збільшуються, а гальмівні – зменшуються. При підвищенні частоти ДЗН до 500 Гц щільність струму в обмотці якоря перевищує аналогічну величину в обмотці індуктора.
