Abstract

Inventia se refera la o metoda de reducere a perturbatiilor radioelectrice produse de aparatele si instalatiile electrice-actionate de motoare electrice, ca de exemplu, masini de spalat rufe, vesela si alte instalatii electrice, conform inventiei, în scopul filtrarii curentilor perturbatori produsi de contactele electrice ale unui programator sau alt element de comanda care asigura actionarea repetata a motorului electric, consta în folosirea inductivitatilor proprii ale unor parti ale înfasurarilor statorice si ca elemente ale unui filtru de antiparazitare, prin intercalarea acestor contacte electrice între înfasurarile statorice separate, apoi conectarea la bornele motorului a unui filtru de antiparazitare, astfel încît inductivitatile proprii ale înfasurarilor statorice sa înlocuiasca sau sa completeze inductivitatile proprii ale filtrului de antiparazitare.The invention refers to a method of reducing radio-electric disturbances produced by electrical devices and installations driven by electric motors, such as washing machines, dishes and other electrical installations, according to the invention, in order to filter the disturbing currents produced by electrical contacts of a programmer or other control element that ensures the repeated operation of the electric motor, consists in using the inductances of some parts of the stator windings and as elements of an anti-interference filter, by interposing these electrical contacts between the separate stator windings, then connecting to the terminals the motor of an anti-interference filter, so that the self-inductances of the stator windings replace or complement the self-inductances of the anti-interference filter.
