The feed of electric motor comes true from the system of power supply of alternating three-phase current with nominal tension 115/120 V and by permanent frequency 400 Hertzs. Cooling method - from the ventilator of cooling of brake of wheel, that is set on the billow of electric motor on an object, and convention. In the aluminium corps of electric motor incorporated: - stator; - squirrel-cage rotor; - annunciator of rotation of the rotor consisting of a stator and rotor; - two-channel tachogenerator consisting also of stator and rotor. Connecting of electric motor to the power supply and signaling circuits is realized through plug electrical connector. Tachogenerator made on the basis of the annular permanent magnet mounted on the rotor. Cores of rotor and stator of the tachogenerator have a scalloped shape and contain 132 teeth each. Work of the tachogenerator is that when the rotor of the ttachogenerator changes the conductivity of the magnetic system, Consequently, the output coils on the stator of the tachogenerator induced electro driving force sinusoidal form. Frequency signal proportional to the rotational speed of the rotor. During one turnover of the rotor ttachogenerator 132 outputs a pulse. Work of the annunciator of rotation of the rotor based on the fact that a rotating magnetic field of the permanent magnet mounted on the motor shaft, induces in the stator winding of the indicator electro driving force proportional to the rotational speed of the rotor. Annunciator is designed for determination of the ability to work of an electric motor Product Description popup.authors Лиховченко Дмитро Віталійович popup.nrat_date 2020-04-02 Close
