    ASYNCHRONOUS MOTOR WITH A HOLLOW PERFORATED ROTOR by A. N. Annenkov, S. V. Sizikov, A. I. Shiyanov

    Published 2018-04-01
    “…With the rotation speed increase, due to the presence of the windows on one end face of the rotor and to the impact of the bottom of the barrel on the other one, the elementary currents of the rotor within the active length of the machine boring would be directed mainly in the axial direction, including the cases of comparatively small slippage that corresponds to the small frequency of the alternating magnetization of the rotor material. I. e. a certain part of the active surface of the rotor on the end that is opposite to the bottom of its barrel would not function as the frontal part of the winding while reducing the frequency of currents in the rotor material. …”
