    An improved rotor assembly for a dynamoelectric machine having poles which are provided with slots that form channels to receive a retaining cover or wedge to retain field windings located in a recess between adjacent poles. The slots cooperate with lips on each end of the retaining wedge to prevent the wedge from deforming and separating from the rotor as a result of centrifugal forces developed during high speed rotation.

    专利说明:

    The invention relates to electric machines, in particular to pole-mounted rotors of electric machines. A rotor of an electric machine is known, comprising a magnetic magnetic conductor laminated from a plate with a carrier coil of an excitation winding cores and pole pieces and inter-pole wedges holding the coils of the excitation winding from centrifugal movements. However, the interpolar wedge in this design has the necessary strength and rigidity, which are provided by the thickness and shape of the wedge, which has a considerable mass and is difficult to manufacture. A rotor of an electric machine is also known, which contains a pole-pole magnetic circuit with a carrier coil and an excitation winding with cores and pole tips and an interpole wedge made of plates and made in the form of curved plates fixed under the flanges of the pole pieces. At the same time, the wedge surface and its mass are significantly reduced, but under the action of a distributed centrifugal load from the excitation winding held, bending deformation of the wedge is possible, which can weaken the wedge anchorage on the inner surfaces of the poles of the pole ends, which reduces the reliability of the winding fastening. The purpose of the invention is to increase the reliability of the fastening of the winding. The goal is achieved by the fact that on the side surfaces of the core plates there are protrusions adjacent to the lower parts of the ends of the interpolar wedges, and the wedges have thickenings included in the grooves formed by the magnetic core plates on the lower part of the pole pieces. 1 shows the proposed rotor of an electric machine; in FIG. 2, the magnetic rotor of an electric machine in the zone of fixing the interpolar wedge under the pole piece, the cross section 1e. Electric rotor The meilines contain a pole-type laminated magnetic circuit with pole cores 1 and pole pieces 2, coils 3 of the field winding and inter-pole wedge 4, made in
    a curved plate with rectangular bulges 5 at the ends that fit into the grooves 6 on the inner surfaces of the pole pieces 2.
    When the electric machine is operating, the centrifugal force from the excitation winding 3 acts on the plate of the wedge 4 in the interpolar space. This force can lead to bending deformation of the wedge plate 4 and the output of the bulges 5 from the grooves on the inner surfaces of the pole tips 2
    To prevent the bulges 5 from escaping from the grooves of the pole tip 2 on the side surfaces of the pole cores 1, protrusions 7 are made adjacent to the bottom surfaces of the ends of the wedge 4.
    This design minimizes the deflection of the wedges under the action of centrifugal forces. The dimensions of the protrusion and the shape of the groove and the thickening of the wedge are chosen so that the wedge can easily fit into the groove during assembly.
    Thus, the fastening reliability of the rotor winding increases with a minimum thickness of the wedge plate, which is especially important for highly used electric machines, such as aircraft.
