FIELD: hoisting devices.
SUBSTANCE: invention refers to electric drives of machineries of various purpose. Device consists of asynchronous electric motor with squirrel-cage rotor, traction sheave and brake system. Asynchronous electric motor is made with electric reduction that is formed by the fact that stator winding consists of "i" separate two-layered windings designed for overall supply voltage, and galvanic unconnected and isolated from each other, and each of them occupies "1/i" part of stator circle. External sides of sections of each winding, which comprise its extreme poles, are put together with external sides of sections of neighbouring windings into common stator slots. Poles of neighbouring windings at the joint of windings are of opposite sign. At that, i - integral number not less than 2.
EFFECT: increasing reliability of asynchronous electric motor of special configuration.
