Electric motor with a thermal switch positioned at a distance from a stator for household appliances
Patent number: 10186928Abstract: The present invention relates to an electric motor used in household appliances such as washing machines, comprising a rotor, a stator, more than one winding the diameter and coil number of which are determined according to the desired power and the number of revolutions, more than one terminal to which the winding ends are connected, a connector wherein the terminals are situated, fixed on the stator and which provides the electrical connection between the windings and the external power source and a thermal switch connected in series to the windings, which cuts off the electric current passing therethrough and stops the operation of the electric motor by detecting the increase in the current that occurs due to reasons such as excessive load and mains voltage variability.Type: GrantFiled: December 21, 2012Date of Patent: January 22, 2019Assignee: ARCELIK ANONIM SIRKETIInventors: Asuman Firat, Cihad Ekin, Huseyin Orhan, Emin Gultekin Sonmez, Yakup Imat -
