Abstract

Relejni prekidač za monofazne elektromotore, koji koristi zavisnost napona na krajevima pomoćne faze (2) od brzine okretanja rotora monofaznog elektromotora sa rotorom u kratkom spoju u funkciji uključenja i isključenja kondenzatora u električno kolo radi dobijanja velikog polaznog momenta, ima za novost to što je kalem (4) preko svojih izvoda (0-IV) povezan za krajeve pomoćne faze (2) i u zavisnosti od napona na kalemu (4) povlači se kotva (8) zajedno sa kontaktnom pločicom (10) čemu se suprostavlja opruga (5).[Reley switch for the monophase electromotor, using the dependence of voltage at the end of auxilliaryphase (2) from the rotation speed of the rotor of monophase electromotors with a rotor in the short circuit in the function of switching on and off the condenser in the electric circuit for the purpose of obtaining great initial momentum, characterized by novelty that the coil (4), by means of its extensions (0-VI) is attached to the end of the auxilliary phase (2), and in the dependence of voltage on the coil (4), anchor (8) is pulled along with the contact plate (10) that is confronted by a spring (5).
