  • Patent number: 10199892
    Abstract: The present invention relates to a spoke-type permanent magnet rotor (1) used in brushless direct current electric motors (12), forming the rotating part inside the stator (13) that forms the stationary part thereof and having an air gap (14) between the inner surface of the stator (13) and itself, comprising a cylindrical core (2) produced from ferromagnetic laminations or ferromagnetic powder metal, a shaft (3) fixed to the core (2) and forming the rotational axis of the rotor (1), a hub (5) disposed at the center of the core (2) and having a shaft hole (4) that bears the shaft (3), more than one pole segment (6) disposed all around the hub (5), more than one magnet slot (7) disposed between the pole segments (6), more than one magnet (8) tangentially magnetized, placed in the magnet slots (7) and extending outwards in the radial direction, and two end rings (9) produced from non-magnetic materials such as aluminum and plastic and fixed on the front and rear planar surfaces of the core (2) by the injection

  • Patent number: 10186928
    Abstract: 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.
