摘要

Drive system for elevators, escalators, walkways and wind turbines of the type which has mechanical drive by means of electric motor with a stator and a rotor constituu00ecdo and, in the case of elevators.A system of emergency when power outage occurs and a traction system has an induction motor with rotor in the form of a cage with low starting current and high performance and an asynchronous motor to work in the said drive system, it is possible to measure the power and The speed of operation.By varying the frequency and oltagem entry for between 2 and 2000 kW of power in different designs of engines, depending on its size and physical connection, and the speed proportional to the frequency programmed.
